Sunlight that comes into the house is phenomenal for fading carpet, drapes and furniture. The heat from it can also damage electronics and digital items and cause wood to warp.
In addition to its blocking power, solar window film can passively reflect and absorb up to 70% of incoming solar heat which keeps it from entering the house. Don’t put up with damage from “natural elements” inside your home. Protect your material items, keep them in excellent shape and make them last longer.
