Solar Gard window film is ideal for any property where maintaining sunlight while reducing heat is important. Solar Gard Window Films are thin, multi-layered pieces of optically clear film that are retrofitted to the inside surface of glass to help you save significantly on energy costs, maintain a more comfortable and productive environment, reduce interior fading and improve exterior appearance. Manufactured by Bekaert Specialty Films in San Diego, Solar Gard films are sputter-coated with durable, exotic metals such as titanium, stainless steel, copper, gold, silver, aluminum and other alloys. These varying combinations of metals are what gives Solar Gard its exceptional solar performance capabilities and color.
