SOLAR PROTECTION GLASS PACKETS

The sunbeams not only provide light, but also a major part of the heat energy (solar energy). For buildings with large areas of glass on the south side, it is recommended to use special glazing that will trap solar heat in warm weather and reduce indoor heat loss in cold weather.
