The sun is the main cause of warming during the summer, which penetrates through glass surfaces excessively warming rooms in which we live, and this facade allows us to prevent that warming or to use it.
The biggest advantage of the double over the single facade is in less energy for cooling or heating of the building.
Main advantages of double-skin to single-skin facades manifest itself in winter time:
Solar energy is used as a natural resource by creating heated insulated layer, which improves thermal insulation of a building. For the best results Feal uses low emission glass (low-e has a thin metal layer which allows solar energy to go in and keeps it inside the facade).
Lower energy costs.
This solution offers longer life of the facade and better use of solar energy. The outer facade layer provides protection from weather conditions and acoustic insulation from external noise.
