Window film: a low-cost way to cut summer heat gain, glare and UV fading. It works best on sunny south and west windows in warm climates and can reduce helpful winter sun, so check the NFRC label for solar heat gain (SHGC) and visible light (VT) ratings, and make sure the film is compatible with your glass and window warranty. Makers and installers below are commercial.
