Multi-purpose window supplement

Research subject and fields:

Windows are, from the point of energy, elements of buildings with a great coefficient of heat passage in comparison with walls, the ceiling and the floor. By means of various window supplements the window insulation can be improved with more or less success. The new multi-purpose window supplement has, because of its design and its application, good heat-insulating and darkening properties and can be fitted on already built-in windows, with the outside fittings. The results of investigating the heat-insulating properties of the new multi-purpose window supplement in several variants, including the existing window supplements, are the ground for the new product, the multi-purpose window supplement, which is suitable for serial production, is simple application and gives positive effects.
