SOL 158 Solar Protection 52%

Sun Protection 52%, Silver Points

SOL 158 solar protection film is engineered for application on windows to reduce sun-induced heat and glare. It significantly contributes to enhancing comfort and energy savings, particularly by decreasing the reliance on air conditioning. Utilizing its micro-dot technology, it stands out as the only film capable of rejecting more heat during summer than in winter.

Composition of Heat Protection Films

Adhesive solar protection films consist of two layers of metallized polyester under vacuum, an adhesive layer, and a protective film that should be removed during installation. They are treated to resist scratches.

Solar Factor

The solar factor (G) of a window pane represents the ratio of the total energy entering a room through the pane to the incident solar energy. This total energy encompasses both the solar energy directly transmitted and the energy emitted by the window due to heat absorption, which contributes to the interior environment.

Greenhouse Effect

Solar energy entering a room through windows gets absorbed by objects and interior walls, which, as they heat up, emit thermal radiation primarily in the far infrared range (wavelengths greater than 5 μm). Glazing, even when it’s clear, is nearly opaque to radiation with wavelengths exceeding 5 μm. Consequently, the solar energy that enters through the window remains trapped within the room, causing it to heat up. This phenomenon is commonly known as the « greenhouse effect, » similar to what occurs in a car parked in the sun with closed windows.
