The ape Building facts you've never heard about: Did your audacious restoration, renovation, refurbishing, reconstruction, remodeling, improvement, rehabilitation or modernization of your historic building change to a disaster? Have you lost all your money and hope?

Death skeleton Did you insulate your old house, your ancient hut or the new ecological barrack completely by thermal insulation and did you lock it hermetically and airtight? Does the mold fungus / mildew grow at the walls and in the roof? Is your private gas chamber poisoned with insecticide, fungicide, algicide, pesticide, synthetic softener, solvent and fire protection? From the ceiling the water drips and the dry rot grows? Suffer your children of skin disease like dermatosis, seborrheic or atopic dermatitis, psoriasis with blisters, edema, formation of a crust, moist discharge, crusting, scaly papules and plaques, itching, allergy and eczema from the front to the back, from the top to the bottom? Do all have asthma and cough? Are your tearing eyes and thumbs completely blue now?

Had you always found the perfect experts, chartered surveyors, builders, firms, craftsmen, restorers, architects and engineers in your neighbourhood and fabulous consultants in the InterNet Forums? Could you take advantage of the best and cheapest offers of the market to refurbish your worthful and very ancient gem made from wood, stone and mortar with the super modern building materials which can be used so quick as a tempest storm and must not fit to any physical behavior and stylish outfit of your old fashioned construction?

Did your splendid architect get your money for the planning which his industrial friends and producers of building materials gave to him? Free for him but too expensive for you. And so comes up a 'solution' which is neither cheap nor fitting to your low budget? This isn't rare at the rescue of the cultural heritage. However, you don't know it. And have you realised the most expensive perfect nonsense in your house now? I congratulate! But: Perhaps your work may succeed still better, healthier and even many more cheaply? Do you know how?

Building Rehabilitation, Conservation, Preservation, Repair, Maintenance, Restoration, Renovation for Public and Private Use

You are welcome cordially and thank you very much for your visit. This web site waited for a long time just for you. Perhaps it is not too late for you and your historic house? Here you will find free, independent, critical and controversial information for many questions and problems regarding your house. Topics: The repair of old buildings by low price, the restoration of historic monuments and the preservation of valuable works of art, energy efficiency with respect of building construction and heating methods. The information is mostly in German language. Some pages are in other languages (English, Russian, Italian, Danish, Swedish ...) and now first time in your language. Thanks to machine translators ;-) Please: If there are misspellings and grammatical faults in the text, send me the improvement. That will help all visitors. Thank you!

Famous and recommended home repair and advice books from one of the best British authors and the UK's top (and only?) building expert, my dear colleague: Jeff Howell, webmaster of AskJeff.co.uk:

But why this text in your language now? Because also in your country old houses, buildings and historic monuments with their external and internal parts form the foundation to the roof, from the fresco to the furniture must be restored. Many technical and economical problems and other questions we have in common. The errors too. With the same disasters for the historic buildings, the ancient monuments, old houses, medieval castles and renaissance or baroque palaces, for the mansions and city halls, for the churches, monasteries and abbeys, for antique temples, synagogues and mosques, for the winery and brewery, for the villas of the merchants and the mansions of the citizens and craftsmen, for the farmhouses and the huts of the poor people, and for the stables of the horses and cows. Is it magic, ritual and witchcraft in old houses, which blames all your desperate efforts to get them in better shape? Other crafts? The international building industry and your experts don't sleep. This will also cost your money. Do you want to see examples? Click the pictures for further information:

Is this information controversial and unusual? However, the information corresponds to the old one Tradition and art of the skilled crafts. Many years experience at the restoration work are the basis: Historic monuments and ancient buildings from the farmhouse to castles, manor houses, mansions and ecclesiastical buildings like churches and monasteries. Also my father had been architect and did this conservation work since 1958 until his dead 1979, when I started. I could learn much from him. After my studies I had been a scientific volunteer in the office for care of monuments in Munich for two years.

The best specialists of the industry, the famous experts from the handicraft, the very trustworthy engineers, the always dark black dressed architects and also your so friendly friends nearby will have mostly another opinion. Perhaps they will give better advice. But you must decide by yourself whether my information for you is meaningful and useful. However, you also can follow your wise experts on the broad one Street of the success (only for the experts?).

Perhaps you can find no answer to your questions here. Alternative: You will find over 1500 pages to all these topics and more in German language: Restoration, preservation, conservation, technical and historical investigation and survey of buildings, building materials for old houses: Brick, lime, mortar, plaster, brick-work, half-timbered framework, concrete, painting from synthetic resin and potassium silicate, restoration and strengthening of sandy and corroded natural stones, problems with the restoration and renewal of the house and its parts from the foundation to the roof, economy and financing, deceit and corruption at the industry and the planning of houses and restorations. Last, but not least - an adventure: The climatic change - what's true? Here you can find the way in:

- You want to buy a German castle or palace? Do you want to know the selling price? Examples: Palace / Castle / Manor-house / Mansion for Sale.

- Ascending dampness, moistness and rising damp. Here you find, what can be made wrong against dampness, wetness and salpetre salts in the moistured masonry of walls and brick-work, in the cellar and in the foundation, at the front and in the layers of plaster. Ineffective, destructive and very expensive masonry drying methods and salpetre treatment like brutal horizontal isolation by chemical injection in drilled holes (borehole injection), drilled metal plates or foils after masonry sawing, hermetic mortars and paints with synthetic resins and very funny electronic dewatering / electrical damp-proofing by electro-osmosis. Methods, which do not work and make all worse: The largest business for the swindlers and damp proof companies not only in Germany. Also in English language: Rising damp does not exist

The ascending and rising damp in the brick-work and masonry does not exist! The House in the rising water - no ascending and rising dampness! Quai wall in the port - no capillary ascending and rising dampness! No capillary ascending and rising dampness in the brick-work and masonry - not in the laboratory, not at the building in the water, not at all at the brick-work in the harbour. But why? Because the capillary transport from the material with small pores (like brick and natural stone) into the material with large pores (mortars) is impossible! Enlighten yourself! And the capillary transport in the pores of the stones and the mortar joints will not defeat the gravity more than 10 to 20 cm. Only the water-waves and the salty water of the high tide make the walls wet! So it is in good old and modern Germany, should it be possible nevertheless in your so beautiful and mysterious country? Test it yourself in your bathroom, if you don't want to believe this! Don't believe in bad guys and silly theories. Don't believe me too! A colored silk tie neither and a silver shining big car nor a colored web page can improve bad advice! And what will you believe? Hoax and witch work? Enlightenment must be! But if you will do it yourself, you must buy construction material or masonry saw to pick out your experimental unit from a building wall. Then start and try and error!

There are many problems to solve in repairing and modernizing old buildings for new usage. The most money is lost not by bad work, but by bad planning. That's true and not a newly made knowledge. But to find the best way to repair and refurbish, to conservate and to restore and to rehabilitate, you must find out the building's substance, the building's structure and the reason of it's damages by researching and analyzing. Afterwards you have to find and proof the superior alternatives to give the building a new modern and fit for future function and a new (or antiqued?) shape if necessary. This all by economical invest and trustful technique, what means a neutral and independent planning too. What will naturally not exclude the need for best practise craftsman and suppliers in the later coming phase of working out and building all the good ideas after a fair participation in the awarding of contracts. A special challenge is to make an old building accessible for handicapped people. However, with the right partners including a lifts expert or maybe manufacturer and an experienced architect, it should be possible. But please remember the following: Not all modernizing, not all changing, not all destroying may be necessary, useful or allowed to a honest preservational purpose. You must alway consider what's worthful and what's needed and what's a really must be for the good old house. The abdication of exaggerated renewing is perhaps the most important feature of the true lover of historical buildings and best practise maintaining our national heritage.

"Maurice Strong, Al Gore
Creators of carbon credit scheme cashing in on it
By Judi McLeod

There's an elephant in global warming's living room that few in the mainstream media want to talk about: the creators of the carbon credit scheme are the ones cashing in on it.

The two cherub like choirboys singing loudest in the Holier Than Thou Global Warming Cathedral are Maurice Strong and Al Gore.

This duo has done more than anyone else to advance the alarmism of man-made global warming.

With little media monitoring, both Strong and Gore are cashing in on the lucrative cottage industry known as man-made global warming.

Strong is on the board of directors of the Chicago Climate Exchange, Wikipedia-described as "the world's first and North America's only legally binding greenhouse gas emission registry reduction system for emission sources and offset projects in North America and Brazil."

The R-value as thermal barrier without any good effects
This diagram points the consumption of energy to heating rooms with different constructions of their walls. The Rth-value (= k-value) without any sense as benchmark, gauge, norm, touchstone, scale or criterion for thermal barrier and effect I. Research from the Fraunhofer-Institut in the winter 1983. x-axis: k-value of the wall construction; y-axis: Consumed Watt of heat energy in the measured time. Purple and red: Thermal insulation with 23 and 10 cm polystyrene. Green: Only brick.

And here an excerpt of an expert opinion /report / statement done for the owner of a residential apartment in a skyscraper in Southern Germany (Translation by Google, still in improvement):

The swindle with thermal insulation and energy saving

An advisory opinion (excerpts)

Address Lawyer

Address Client, ./. condominium owners of residential apartments regarding the resolution contestation (Beschlussanfechtung)

Short statement to the planned facade repair

1. Client: …

2. Ground of the short statement

The statement is done as argumentation support for the resolution contestation against the planned facade repair in ... with an external thermal insulation composite system (ETICS)/exterior insulation finishing system (EIFS).

3. Building specification

The messuage in ... is a multistoried building with eight floors and 32 living apartments, built in reinforced concrete skeleton construction. It was established approx. 1965.

4. Building construction front

The reinforced concrete construction is up from the 2nd floor coated with asbestos cement panels (Eternit sheets) on thermo-insulating magnesite-bound woodwool boards (Heraklith).

5. “Thermal insulation” of the fronts

5.1 Planned measures

According to planning of architect ... after strapping off the Heraklith panels the fronts will be coated with 14 cm thick expanded polystyrene boards (fabricate ... on base of Neopor®, with graphite added) on adhesive mortar, whereupon a synthetic resin plaster is coated, reinforced by embedded synthetic netas armouring against temperature stresses (temperature extension of polystyrene: 8 mm/m x 100 K, reinforced concrete and cemtent plaster: 1,2 (!) mm/m x 100 K). As surface layer of the so-called extern thermal insulation composite system (ETICS)/External Wall Insulation System (EWIS)/Exterior Insulation Finishing System (EIFS) thereby a coating equipped with pesticides (algicides, fungicides).

The original wooden windows shall be exchanged against airtight and extremely dense plastic framed insulating glass windows.

To what extent the substantial shape change would be acceptable by the planned coating measures with adequate appreciation of the aesthetical interests, is not subject to the evaluation of the signer.

5.2 Evaluation of the polystyrene coating in build-constructional regard

The extern thermal insulation composite system (ETICS) with imbedded graphite powder in order to reduce the penetration of radiant heat through the facade is a lightweight construction system with very small heat storage capacity. In contrast to a solid wall surface the radiation exchange of a lightweight construction with the cold night sky leads to a short time lose of the heat taken up during the day by diffuse and direct solar radiation. While solid surfaces even at longer frost periods very seldom drop under the outside temperature, on the very cooler surfaces of insulating layers condensation will wet up the surface nearly every night and will occasionally freeze and destroy the facade. You can proof this by yourself, only use a IR-Thermometer

Frozen and algae infestated thermal insulation-ETICS / External Wall Insulation System EWIS/ Exterior Insulatin Finishing System EIFS-coating Ice, frost and algae on extern thermal insulation composite system (ETICS) / External Wall Insulation System EWIS/ Exterior Insulatin Finishing System EIFS

Illustration: Frozen and algae infestated / affected ETICS/EWIS/EIFS coating

The temperature reduction of the surface under the temperature of cooling down night air favours the dampf condensing on and in the coating system. Air humidity penetrates behind the diffusion-open coating and condenses in the cooler internal area of the coating system.

A further humidification of the insulating material occurs in connection with the mentioned large temperature strain of the insulating material system. The substantial temperature strains of the system lead after some time despite the constructional counter measures (reinforcing) - according to experience - to cracks in the coating system. The cracks forming in the Coating work capillary-actively and aspirate rain water.

As the coating system does not permit considerable capillary drying process, a substantial risk of drenching and soaking of the system is connected by condensate admission and at longer term unalterable cracking at the surface.

In order to decrease the big risk of the fungi / mold and algae infestation, the synthetic and thus dry-blocking paint for the coating is equipped by added toxic algizides and fungicides (after manufacturer data: A compounded mixture from Carbendazim, Terbutryn and Octylisothiazolinon), which are out washable by spray irrigation after dismantling of the water-rejecting / hydrophobe substances first and so on longer sight their defense effect fades out.

The ETICS blocks substantial parts of the solar radiation into the solid construction behind. The graphite imbedding in the insulating material also increases the need of heat energy in the winter by decreasing the solar radiation into the front.

As result the whole facade system will suck up condensate and will be damped. This wetting effects are connected with more and more damage of the reinforced concrete by corrosion. As the ETICS/EWIS/EIFIS facade construction takes up less solar warmth, this cooling effect will lead to increased heating costs.

A gradual drenching of the entire facade system with the following mold fungus risk in the interiors probably is followed by the planned installation of the new air tight plastic windows.

Altogether in a long-term view the outside changes by coatings with insulants will cause unfavorable consequences not only for the facade system but also for the heating energy consumption and the healthy dwelling.

The inclination of dampness storage and formation of mould in insulating materials is shown also by old mineral wool insulations in roof structures. They show the black-grey discolorations typical for it which starts from the boundary region to the timber construction. Not only condensate from room air is stored, but also the self-dampness from the timber wood.

5.3 Evaluation of the polystyrene coating in energetic regard

5.3.1 Preface

After usual viewpoint a thermal insulation system shall lead to smaller heating costs. This contradicts however the following specified facts.

5.3.2 The Rth-value/heat conduction / thermal conductivity term as hyperbolic function

The Rth-value is a hyperbolic function and is calculated: Rth = 1:1/a i + 1/L + 1/a A (W/m ² K)

From it results:

Thickness of insulating material and the improvement of Rth-value in (W/m²K)

5 cm 0,8

10 cm 0.4 50%

20 cm 0.2 50%

A duplication of the expenditure halved therefore the effect, with rising insulating material thickness decreases the efficiency.

As diagram that shows up as follows, the indicated k-value is identical to the today valid Rth-value:

The hyperbolic function of the R<sub>th</sub>-value

The hyperbolic function of the Rth-value. The efficiency border is with approx. 6-8 cm thickness of insulating material (source: Professor Dr.-Ing. Claus Meier, Richtig Bauen, 4. Edition, expert verlag 2007).

As consequence higher thicknesses of insulating material cannot be realized as in the given case with 14 cm under economic criteria.

5.3.3 Relevance of the heat conduction /thermal conductivity

A substantial result of a critical view on insulating projects in the reality is that the typical insulating materials without heat storing capacity in opposite to the solid construction materials have not a remarkable insulating effect at the front. They shadow the solid wall behind and thus diminish the storing of sun energy by solar radiation.

This corresponds also with the results of measurement the Fraunhofer institute to comparative constructions of different k and/or Rth-values of the external walls (data source: Fraunhofer Institut for building physics, 1983).

The area with allegedly bad k-/Rth-value needs the smallest heating energy for the same ambient temperature according to the result of measurement:

Energy consumption in areas with differently insulated walls ETICS/EWIS/EIFS

The fact that the real thermal behavior of materials does not agree the calculation formulas on basis of the Rth-values, under the conditions of practice with, could be approved by a newer investigation of the federal research institute for agriculture FAL, institut for operating technology and building research under Professor Dr.-Ing. Franz Josef Bockisch over an entire yearly duration at an experimental construction.

Here a result of the measurement in August:

Temperature development at front material in reality and theoretically according to DIN

Red (line curve) the measured values, blue (broken) the standard arithmetic procedures (source: FAL, Dipl.-Ing. Karl William Haake)

The undercooling of the outside inner wall in relation to the external layers and condensation susceptibility by dampness admission from outside air is clearly shown here.

Likewise as result of the FAL research here an excerpt from the February curve with representation of the measured temperature gradients at the different front directions.

The substantial temperatures at the front surfaces (bricks) prevent by heat storing effects the cooling and condensing under the night air temperature (blue: air temperature in accordance withGerman weather service station on testing grounds) and thus the condensate admission :

Temperature development at front material and theoretically according to DIN

The futile insulating attempts at large buildings are shown by Professor Jens Fehrenberg, University Hildesheim, by comparing the energy consumption of neighbouring apartments with approx. 25 dwellings before and after insulating over many years.

In addition the external wall is involved only with 10 to 20% in the loss of energy of buildings, so that improvements made here can have only marginal effect on total energy consumption.

See for this the contribution of Professor Fehrenberg in: Deutsches Nationalkomitte Denkmalschutz (German national committee for monument protection) DNfD (Hrsg.): “Energieeinsparung bei Baudenkmälern (Energy saving at architectural monuments)”, documentation of the conference of the DNfD from 19.3.02 in Bonn, volume 67.

The first diagram which is based on it shows the heating costs of the three blocks of flats at Tollenbrink in Hanover, determined by Professor Fehrenberg.

Energy costs in comparison insulated and not insulated fronts of same buildings

The actual heating costs of the house 6 before and after insulation by an ETICS remain in the same range as the not insulated apartment houses No. 2a and 4:

With the following diagram Professor Fehrenberg shows the influence of the energy consumption at three large's buildings in Hanover only by the average temperature of the heating season. The accomplished thermal insulating measures with ETICS (entry “San.”) have therefore no remarkable influence on heating consumption:

Energy costs by comparison insulated and not insulated fronts of same buildings

Also the investigations of the civil engineers Wichmann/Varsek at the Justus-Knecht-Gymnasium in Bruchsal prove the real conditions of heat consumption of a solid brick masonry wall in winter (February). Therefore temperatures up to 30 °C result in the case of an outside temperature of approx. 8 °C by consumpted solar radiation on the solid surface. By the nocturnal heat emission the temperature of the solid wall drops again, remains however always substantially over the outside temperature and remains condensate-free thereby.

The following illustration shows the result of measurement:

Material temperature development at front in the winter

Source of picture: Rationeller Bauen, February 1983

5.3.4 Economy of an auxiliary insulation of the front

The last yearly consumption of the heating serves as basis of an economic evaluation of the planned energy saving measures by window exchange and auxiliary thermal insulation. Thus the future heating energy consumption of the building and the saving potential as return of investment (ROI) for the building costs can be estimated.

The average annual consumption (2003, 2005, 2006) of 14,03 litres oil/square meter and a fuel oil price of 0,4 EUR/liter will cause yearly costs of 16.524,22 EUR. Assumed a saving of (unrealistic) 40 per cent by the planned energy saving measures, this results in an annual saving of 6.609,69 EUR.

Thus the costs for energy saving measures are limited to maximally 79.316,26 EUR in the case of a usual MNV (Mehrkosten-Nutzen-Verältnis, extra costs/effects relation) of 12. The planned energy saving measures with total costs from far over 400.000 EUR are thereby extremely wasting invest capital.

Also if KfW credits / loans / subsidies for the front repair and the energy saving measures are given and the results for the total costs and energy savings are calculated correctly the whole calculation will never end in an economic solution.

Result: After the vouchers specified here it gives as well as no energy saving by Rth-optimized insulating coatings on solid fronts. Regarding the cost situation the planned energy savings investments will not give a good return and will never be profitable.

6. Fire protection

Despite the insulating materials coming to use are equipped by toxic flame retardants and of low flammability, with reaching of the ignition temperature by external influences they heavily increase the fire risk. An example of an explosive ETICS fire out “Schadensbilde Aktuell / fire damages up-to-date” of the Bavarian Fire insurance chamber may clarify that, also in Berlin in the meantime such cases of fire damage become known:

Explosive flame resistant / retardant heat insulation front/ETICS/polystyrene front in fire

8. Further references

The references and evaluations given here are based on my practical project experiences in the building renovation since 1979 as well as on consulting of relevant project and research documentations.

The references follow the proven methods and not necessarily the industriallaterally affected and not always DIN standards and other alleged rules of the technology applicable for the building renovation.

To the group of topics altogether I recommend supplementing my info pages on www.konrad-fischer-info.de/213baust.htm, ... /7fehrtab.htm, and .../7waefe.htm, in each case with following pages.

The Thermography-Hoax

Thermography - a hoax
Original text under the picture: "A thermal imaging of the front proves large losses of the heat. Measurement at temperature outside 10oC, still wind and unknown temperature in the room. A cause for the visible loss of the heat is that the window is implemented in solid masonry." From the Danish newspaper Byg Tek (Building Technology) 25.10.04 of journalist Michael Rughede.

However, that's only advertisement of the international chemical industry and the manufacturers of non energy conserving but wasting insulating material for dummies. What you must konw: The producers 'can' be connected financially and by splendid gifts with 'some' engineers, architects, craftsmen, scientists, officials of the state, politicians and media. They all want to sell airtight houses and maximum thermal insulation to you to fill their purse with good percentages.

The picture shows only the radiation of the heat from the surface of the solid wall at 12 o'clock. The warmth comes here only from the sun. In the south the wall radiates much and red, in the west radiates the wall only little and blue - green cold.

The hoax of IR scanning by infrared thermography from house inspectors to detect heat losses and heating leaking
Another crazy infrared scanning: Insulated wall blue (could not store the solar energy!), the wooden shutters before (!) are radiating heat instead - like the solid walls of the not insulated parts of the front (Image source: Insulation prop at "www.pr-nord.de/stoo_text155.html" - Notice: The profs use anglizationed terms to fake the huge mass of stupid Germans).

The infrared scanning to detect heating losses from houses and heat leaking is another bad hoax of the so called well, no, better super best reputated 'House Inspectors'. Naturally this famous and totally serious guys are creeping around your house just in the early morning, taking their scans when sundown has happened. Then the thermal insulation has cooled off quickly and the bricks and other solid materials will still radiate the huge amount of solar energy they stored during daylight the whole night. A silly fake and best junk science just for you and your purse. Throw away your money with such jokes, it's yours, not mine. Enlightenment!!! More enlightenment! It's really necessary to conserve real energy ...

Convection heating by hot air - convector The usual convector heater: Hot air heats. Head hot - feet cold.
A dusty typhoon in the room or zero wind? Predominantly heat distribution by desert storm air? Convective heat transfer or radiated heat? Much or little consumption of energy? Asthmatic children, flu in each winter by wrong heating? Condensate and mold fungus at the cold walls - or gentle heat radiation from the surfaces of the room? The energy saving heating with thermal radiation needs little technology. Always dry constructions and houses, healthy, cool and pure room air are the result.
Heat radiation heats - infrared thermal radiation Radiant warmth is heating by infrared thermal radiation.
The room air is a little bit cooler than the surface of the room. No airtight hermetic isolation of the rooms, no senseless thermal insulation from expensively packed air in soaked building materials, no condensate into cold surfaces. Much information about the disadvantages of many kilometers of heating pipes in the floor and behind the plaster in the walls, the problems of baseboard heating, also about the better alternatives. Here one of many examples of the cheap and well preserving heating with radiant heat: Thermal radiation heating in the palace Veitshoechheim Palace with thermal radiation heating (english version)

Glass is not penetratable for IR-radiation / heat radiation Electromagnetic waves and glass
Enlightenment!!! A diagram of Professor Dr.-Ing. habil. Claus Meier: Window pane glass is not permeable for the wavelengths of the shortwave UV radiation (< 0.3 µm) and longwave electromagnetic IR radiation (infrared radiant heat > 2.7 µm). So the biggest heat transfer mechanism through windows is never (!) radiation Only the wavelengths of light can penetrate glass. Therefore you can get sunshine in the room and fire protection from fire resistant glass. The light of the fire is visible, the heat of the fire can not penetrate. Glass is opaque to IR-waves. Therefore lenses for IR-cameras must be made not by glass but by IR-permeable materials like zinc selenide or sapphire.

The electromagnetic waves of the light which come in your room through your windows will be absorbed by the inside materials and emitted in the infrared wavelength. Light can heat your room. X-axis: Wavelength and transparency of the window panes. Y-axis: Intensity of the radiation. The heat is transported predominantly in materials by radiant heat (phonons, migration of the electrons). Two window panes filter more free solar energy than one. Double glazed windows will force condensation in the wall. Sealed windows increase the dampness in the room air. This increases the energy consumption for the heating. Therefore modern windows will increase energy consumption and mold attack. Energy conserving must look to traditional building methods of the historic buildings. Look to your poor neighbour's hut and similiar original buildings in the open air house museum. They show intelligence of experienced craftsman instead of worst practise of nowadays modernists. Enlightenment!

Increase of the temperature under different building materials / insulating materials
'The experiment of Lichtenfels': Increase of the temperature under different building materials / insulating materials (4 cm) after 10 minutes of irradiation with a red light lamp. The materials from above: Mineral wool, polystyrene, foamed glass, clay brick, wood fiber, gypsum cardboard, pine wood. x-axis: Time of the irradiation. y-axis: Temperature in °Celsius.

Note: The Rth-values/U-values (= "U") are not common with the changes of the temperature and the practical effect of the thermal insulation. The crazy joke: Enlightenment!!! The experts of R-values define their results without any regard of the time and amount of heating energy in the proof before they start measuring. Heavy materials suck up and store huge amounts of energy. Therefore they can lose much more energy than air filled insulation. Some experts neglect the free daily energy radiation outside the building from the sun and the surroundings in their dark laboratory and soul too. Think about it, then you will detect the reality even if you are no doctor and only a normal stupid guy.

Porous material like modern light bricks, aerated concrete, industrial or ecological thermal insulation are technically very problematic. Mostly they prevent the capillary drainage of the materials by totally or partly lack of capillary activity and with synthetic coatings, what causes severe problems of wetness and moisture storing: The capillary pores of the materials are densed and sealed / 'insealated' by synthetic coatings. The transport of water in materials by capillarity and by diffusion relates 1000 : 1! So if the capillary activity is blocked, the materials will never get out the dampness and moisture. And in the case of front insulation this materials store every night much water in by condensate: The lightweight materials have not any sufficient storing / store capacity for the daily solar radiation and energy.So they are cooling very quickly by radiation change with the icy heaven after sundown. And start to suck condensate from the cooling air outside during the whole night. Many insulating materials are toxified and threaten the health with terrible poisons such as boron salt, fungicide, pesticide, insecticide, algicide. Mineral wool, PUR (Polyurethane), expanded or extruded polystyrene, poly-icynene (open-cell polyurethane) sprayed-in spongy foam, polyester, fibre glass / fiberglass, foamed glass or wood fiber, cementitious foams, perlite insulation, sheep wool, cotton or cellulose wool, hemp fiber or hemp wool, linen fiber, coco fiber, seaweed, sea-grass, light loam, vermiculite - a naturally occurring mineral that may contain asbestos fibres!, wood wool, newsprint recycling, cellulose flakes blown-in and sprayed cellulose are only some typical products for failed thermal insulation which must be wet after more or less time. Enlightenment!!!They give no better thermal insulation than the traditional solid building materials like wood, brick and natural stone. An additional front insulation will increase the heat consumption: by shadowing the wall behind. And all the poisoning and sealing of the insulating materials will not help against humidity problems. This materials store humidity and condensate. That makes the mold fungi like black mold, dry rot, mildew and mites, also lice, ants and beetles, mice and rats very lucky. As soon as the cruel condensate has defeated the synthetic foils, the parasites will come! Besides fiberglass and similar insulation materials can cause severe itching, inflammation and other harms. The clever homeowner should not trust too much in all the computations of the theoretical thermal conduction / conductivity. Consider the sun power by solar radiation. Enlightenment!

Questions and Answers

Dear Konrad,
I am a first time home buyer with a 1890 Colonial home. My first project will be to finish the attic into a master bedroom/bath with cathedral ceiling.I've been researching insulation online and found your comments very interesting. Right now my leading option is Icynene spray which is air sealed.What do you recommend? Pine boards with no insulation?

Dear X.,
Regarding the questions of insulation a lot of errors are widely spread. The common: lightweight 'insulation products' can insulate or reduce the transport of heat energy through materials. The truth: they can't. Energy transport is a flux of energy, nearly like water. Who would build dams with porous sponge? No one. So, why should we do this building dams against energy flux and losses? It makes no sense despite all the hoax of Rth-values.
Our ancestors knew to build correct: lightweight tents (with perfect airation and drying) for mobile dwellings, stabile and solid buildings of wood, adobe, brick and stone for longer lasting ones. Why shall we look for other ways? Because the industrial lobbies of poorly built lightweight prefab-houses will enforce our administration and the building branche, to overwhelm the traditional building systems. The chemical industries, badly educated planners and craftsmen are their willing partners. That's the only reason.
Back to your question: Yes, solid pine (also gypsum materials) works quite good as insulation against heat losses. But why? The heat will force the huge water content in the wood to transform into damp. This will induce a cooling effect on the heated surface. The amount of water is bigger in wood than in brick. So the cooling effect of damp out of materials is a little bit higher than otherwise the perfect insulating storing effect of the dry masonry. See the graphs of the "Lichtenfelser Experiment" above, more info you can find here (in German).
Insulating bath and bedrooms has two main problems - keeping the heat inside and transporting the damp outside. The second problem is a bigger one. Your construction must solve this. So no dampproof foils, no hermetic and air tight room construction, enough damp storing surfaces. Beneath, solid wood has a certain weight, your beams must stand this. To make a correct order of the construction layers is worth to think about in every case. It depends from statics, durable airing by the windows, vents, radiant and convective heating etc.
If you have understood the complex, there's always a solution. If you'll need some more help, you can take advantage of my consult for a minimal fee (see below). In this case you can send me some pics of your building construction of the attic, and than we'll look for a good construction.
Best regards

The role of the memorial monument preservation theory with the practice monument protection and conservation practices are viewed critically. Do you have a wooden house, or stone house, masonry, steel or framework or half timbered house, a parsonage, a monastery or even a cloister abbey? Is your building, which needs or has behalf of a building renovation or building maintenance, a house renovation, the entire building structure modification and reconstruction really totally damaged? Not always does in private property such as houses, commercial real estate, business houses and store buildings house a complete modernization fulfill all needs in a given budget. Even not at an old City Hall, a historic mill, an abandoned train station, the dreamy water mill, or a villa (Art Nouveau villa). And who owes a family home, a multi-family house and a commercial business house or energy-saving building or passive house and is planning a modernization for the old structure maybe even a castle renovation and wants to save money, on this site are many suggestions for him. Even with an upcoming church repair, rehabilitation, a castle renovation and repair the simple methods may be the best ones. Yes, it may be enough with some maintenance with appropriate repair procedures, and it saves money and the nerves. No one needs everytime an overall total renovation of the building substance to renew or to renovate, and the complete renovation is not always necessary. Then suffice here repairing in an economical sense without fulfilling of all norms and building standards and regulations. Contradictory to usual ways only construction and structure repair, always based on intelligence, and humble design! These questions of planning standard and execution or even a norm-contradicting action arose particularly urgent when half-timbered houses or partitions of it has to be renovated or restorated / restored. And if you will buy to owe a summer resort or a noble palace, perhaps you will find it on my luxury real estate sales offer page. The economic issues will be a priority with the cost-effectiveness calculations and cost-benefit analysis in detail.
