naturally reduce the heat being absorbed by the window from the exterior, especially during hot, summer days, when sunlight is directly hitting the home fixtures. Thus, you could observe that temperature near the home windows will be significantly reduced if there are window film products. The result: comfort experienced by occupants is greatly bolstered.
Aside from reducing heat, window film products also naturally block entry of excessive light from the outside. It follows that when light entry is reduced, heat is also lessened. The shades and colors you could see are responsible for blocking up to 99% of ultraviolet rays coming from the sun. In effect, light is also regulated, which is preferred by many homeowners, especially those who have eyes sensitive to too much light exposure.
