ThermoShield History ist eine anwendungsfertige Fassadenbeschichtung für historische Bauuntergründe, die auf der thermokeramischen Membranfunktion basiert. Oberflächencharakteristik und Entfeuchtung wurden speziell für die Bedürfnisse im Denkmalschutz angepasst.
ThermoShield History is a ready-to-use and highly resistant exterior coating with endothermic properties which will satisfy the specific requirements of historic buildings. ThermoShield History is particularly suitable for the roughcast base finishes of historic buildings.
ThermoShield History = Modern monument protection
The configuration and protection of the building material represents a considerable economic challenge. Unsightly residences are not easy to let, and neglected cultural assets such as castles and towers are certainly not public attractions. There is often a lack of funding rather than a lack of will, particularly where damage symptoms have not inspired further financial commitments, even when so-called materials appropriate for monument protection were used.
ThermoShield History, with its tried and tested protection system, is available for those who wish to be really sure. The system not only clearly lengthens renovation intervals, but also prevents considerable damage.
The protective features of ThermoShield History have been proven to be superior in comparison to silicate coatings of a lime paint nature and silicate modified silicone resin coatings (see Torun test report dated 23/05/2004). The regulating and conserving effects of ThermoShield History protect the historical building materials from the natural fluctuations in temperature and moisture to which all buildings are subjected. Conventional coating systems suffer under these fluctuations - and with them, the valuable building materials. By contrast, ThermoShield History deploys its effects on even the most demanding substrates such as wood or clay, as well as under extreme climatic conditions.
The most effective dehumidification mechanism is capillary drying, where water and salt are transported fo the surface of the building from the interior to the exterior. To do this, however, the exterior coating must allow this evacuation and provide an efficient "pump system" of the sorption motor type.
The long-term effects of ThermoShield History have by now been well documented, as our special coatings have been used for monument protection for 20 years. Comparative laboratory tests confirm the positive results achieved in practice with ThermoShield History. These tests include all test criteria relevant to the application.
Economical restoration and convenient living
Durability, ease of cleaning and the retention of restoration of functionality of the building materials that are worth retaining, result in quick amortisation - a category that is seldom considered in connection with paint work. ThermoShield History shows, however, that an old building with protection status need not necessarily be uneconomical. Where the natural functionality of the building material is restored over a long period of time, the energetic functions are also guaranteed as a result.
 The combined warmth/moisture transport can be used to reduce heating or cooling costs due to the active surface of ThermoShield History. This is because radiation, convection and moisture influence energy consumption considerably more than can be assumed from mere consideration of heat conduction.
Using ThermoShield History, not only residential buildings with protection status can be operated economically, but also churches, theatres, castels and other buildings. Long-term applications have shown considerable energy savings - by expending only the normal economic effort for paint restoration.
Furthermore, the expected energy savings from using ThermoShield History can be calculated by simulation.
ThermoShield History creates a healthy living environment without mould formation, allows for quick, even heat conduction in rooms, and provides airing and heating as required, In this way, ThermoShield History creates modern living convenience in historical buildings. By applying ThermoShield Interior inner coating to interior areas, the positive effects are enhanced.
Scientifically proven:
The properties and means of operation of ThermoShield products have been scientifically examined worldwide in the last 20 years. The following report from the Polish research laboratory for building preservation in Torun dated 25/05/2004 is one of the current examinations:
»Test under various destructive conditions have shown that ThermoShield History distinguishes itself by means of extremely high stability and resistance in the chemical environments that were created. Where ThermoShield was applied, and these areas were exposed to these environments for a long period of time, no loss of hydrophobic qualities or substrate adhesion, nor any changes in colour and/or aesthetic changes were noted. ThermoShield History has proved itself to be extremely resistant in cases of extreme temperature and moisture fluctuations, frost and irrigation. No formation of cracks, peeling or colour changes in the coating could be determined.«
Technical feature overview in the comparative examination with silicate and silicone paints
The research laboratory for monument protection in Torun tested three coatings: ThermoShield History, dispersion silicate paints and silicone resin paints.
Resistance to water, acid and alkaline environments
ThermoShield History is more resistant, particularly to the crystallisation effect of water soluble salts. Dispersion silicate paints and silicone resin paints showed peeling and discolorations.
Drying characteristics
ThermoShield History dries the substrate (especially lime sandstone) more gently and carefully than the comparison paints.
Frost resistance with changes in moisture
ThermoShield History is more resistant than the comparison paints. Silicone resin paint peels and dispersion silicate paint displays discolorations.
Pollution characteristics in outdoor weathering (winter industrial climate)
Pollution can be removed from ThermoShield History by means of water. Deposits (particularly soot) cannot be removed from dispersion silicate paints and silicone resin paints.
Hydrophobic properties
ThermoShield History has proved to be the most waterproof coating. Multiple repetitions of the test provided an unexpected result: dispersion silicate paint was shown to be more waterproof than silicate resin paint. The surfuce hydroscopy factor in dispersion silicate paint is approximately 50% lower than in silicone resin paint. The factor for ThermoShield History is in turn approximately 25% lower than for dispersion silicate paint.
Surface hydroscopy and surface hydroscopy factor
ThermoShield History, the modern protection system for the protection of monuments and buildings, meets even the highest demands. Allow yourself to be quickly and easily convinced by applying a test coat.
Practical experience and laboratory tests confirm: ThermoShield History is a protection system that regenerates the weather-affected substrate of the facade and thus permanently protects it from further weather demage. The natural moisture balance of the facade is retained and is not affected by moisture diffusion barriers.
