The UV rays that penetrate your glass windows cause irreversible damage to the interior of your home. All you have to do is reposition your rug, and you'll see the results of fading on your hardwood floors. UV rays cause a chemical reaction in the pigments of floors, upholstery, paintings, and other materials. Replacing your drapes or refinishing your floors every few years becomes very expensive. Instead, invest in UV protection film. The film filters out 99% of damaging UV rays while still allowing beautiful natural light into your space. Installing UV protection film saves you money down the road, because you won't have to refinish your floors or replace your upholstery and artwork every few years due to fading.
