DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
1. Field of the Invention
The invention relates to a compound thermal insulating system that can be attached to a building wall with a light-absorbent external wall surface, which system include an at least partially transparent insulating material protected externally from the effects of weather.
2. Description of the Prior Art
In compound thermal insulating systems known to the prior art (EP-B 0 123 091), a transparent external coating for the absorption of solar energy is provided on the outside of the insulating material in the form of foils or disks of silicate or acrylic glass, particularly pressed glass. Such application occurs in the form of prefabricated units which resemble windows and which are bound in aluminum frames. These units can hardly be used in the renovation of older structures. In the case of new structures their use must be planned as early as the drafting stage. In addition, it is impossible to avoid partition lines with these panel shaped, brick-shaped, or belt-shaped panes. Production of this kind of external facing is not only very complicated, time-consuming, but expensive. It is also very difficult to give this transparent outer coating the necessary strength and stability to guarantee these properties over long periods of time. In addition, the range of architectural design permitted by this compound thermal insulating system is very limited, particularly when it is employed in geometrically complex parts of a facade. Another problem is the fact that, due to the high transparency, a transmission ratio of 50% and sometime more, results so what shading in the form of blinds, shades, or the like must be provided--which devices must, be set by a regulating device or must be continuously manually adjusted. Due to the water vapor permeability of the employed panes, considerable problems with condensation arise in the case of temperature fluctuations, particularly when outside temperatures drop below the freezing point.
SUMMARY OF THE INVENTION
The present invention is based on the use of a the compound thermal insulating system of the type mentioned in such a way that, in a particularly simple fashion, the insulating material is afforded certain protection against external influences, particularly against the effects of weather, without, however, impeding the desired light absorption effect.
The inventive compound thermal insulating system of the present invention provides the insulating material with a weather-resistant protective coating consisting of a filler that is at least partially transparent and contains a quantity of curing binder sufficient to guarantee a radiation transmission ratio for vertical sunlight of more than 20%, given coating thicknesses between 0.5 mm and 6 mm. The weather-resistant protective coating can be applied like conventional plaster, and required solid bond results automatically. Expensive auxiliary devices for bracing, such as those required to secure glass panes, are not necessary in the production of this protective coating of a plaster-like nature. Aesthetically unattractive joints or frame structures, which restrict the range of design in the renovation of old buildings, are unnecessary. By application of transparent insulating material, which permits the penetration of sunlight up to an opaque layer covered by the insulation, and by the subsequent plaster-like application of the weather-resistant coating containing the indicated transparent filler the building can be enclosed inexpensively, very simply, and in a way that both serves to utilize solar energy and is, at the same time, aesthetically pleasing. The system permits the diffusion of vapor, so problems concerning condensation are avoided. The previously necessary application of panel-like, brick-like, or belt-like panes covering the transparent insulation and providing external protection is eliminated by the application of the plaster-like coating according to the invention Also to be emphasized is the fact that the weather-resistant layer eliminates the u
