SOL 158 Solar Protection 52%

Sun Protection 52%, Silver Points

SOL 158 solar protection film is designed to be applied to glazing to reduce heat and glare from the sun. It is a real factor in improving comfort and saving energy in the use of air conditioning. Thanks to its micro-dot technology, it is the only film that rejects more heat in summer than in winter.

Composition of heat protection films

Adhesive solar protection films are composed of 2 layers of metallised polyester under vacuum, an adhesive and a protective film to be removed during installation. They are anti-scratch treated.

Solar Factor

The solar factor (G) of a pane is the ratio of the total energy entering a room through the pane to the incident solar energy. This total energy is the sum of the solar energy entering by direct transmission and the energy given off by the glazing to the interior environment as a result of heating by energy absorption.

Greenhouse effect

Solar energy entering a room through glazing is absorbed by the objects and interior walls which, as they heat up, re-emit thermal radiation mainly in the far infrared range (greater than 5 μm). Glazing, even clear glazing, is practically opaque to radiation of wavelengths greater than 5μm. The solar energy entering through the glazing is therefore trapped in the room, which tends to heat up: this is the "greenhouse effect" that can be seen, for example, in a car parked in the sun with the windows closed.
