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 is a resistant protective coating for all lime and lime plaster exteriors. The excellent properties of this coating allow a wide range of applications, which provides protection of building structures in both the summer and winter months.
Binder – high-elastic acrylic resin
Filler – ceramic hollow microspheres (containing internal gas inside)
Pigment – white titanium dioxide or other pigments
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 to 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 or 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 the mere consideration of heat conduction.
Using ThermoShield History, not only residential buildings with protection status can be operated economically, but also churches, theaters, castles 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 mold formation, allows for quick and even heat conduction in rooms and allows for 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.
Technical feature overview in the comparative examination with silicate and silicone paints
The research laboratory for monument protection in Polish 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.
ThermoShield History dries the substrate (especially lime sandstone) more gently and carefully than the compared paints.
Frost resistance with changes in moisture
ThermoShield History is more resistant than the compared 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.
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 surface hydroscopy factor in dispersion silicate paint is approximately 50% lower than in silicone resin paint. The factor for ThermoShield History in turn is approximately 25% lower than for dispersion silicate paint.
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 coating.
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 damage. The natural moisture balance of the facade is retained and is not affected by moisture diffusion barriers.
