The purpose of 3M and SolarGard sun protection films is to reduce the heat entering through the glass by raising the glass’s reflectivity (which may not be visibly reflective) and absorbing solar energy in the glass.
Typical tinted films primarily work through increased absorption. Tinted glass absorbs solar energy, reducing its transmission into the room. These films are not as effective at reducing heat as reflective films.
Mirror films are films coated with a metallic layer using precision coating technology. The purpose of metallized films is to increase the reflectivity of solar energy from the glass. The effectiveness of 3M and SolarGard mirror films ranges from moderate to excellent (heat rejection).
All 3M and SolarGard sun protection films are transparent and optically clear. UV protection is present in the adhesive, providing longevity to the film itself and offering protection against fading for homes and office furnishings.
3M and SolarGard window films are protected with a scratch-resistant coating, ensuring long-lasting durability and a well-maintained appearance.
