BDF Black Natural film - NA35

Buy Decorative Film's Natural 35 Sun Control and Heat Rejection window film not only gives your window a tinted look but also provides excellent heat rejection. With a mildly dark, black tint, the Natural 35 heat rejection film still adds a decent amount of shade to your window, but it lets in a good amount of visible light. If you want an excellent combination of heat rejection and light exposure, Natural 35 will make a great choice. Buy Decorative Film's Natural Window Films are available in 5% (Very Dark), 20% (Dark), 35% (Medium), and 50% (Light).


BDF NA35 provides various functions such as heat control, and blocking UV rays while letting in a good amount of light. The medium black tint of the NA35 helps reduce glare. The number "35" in its name refers to the fact that it is rated to transmit about 45% of visible light. The NA35's black-tone nature gives it a good heat-rejecting rate of up to 42% that keeps the interior of your home nice and cool. 


The NA35 achieves reduction of incoming heat with a balance between letting light in and having some shade. Because of the medium shade that allows more light to pass through than other darker films, the NA35 provides an excellent view out the window with a mild level of view-shielding. This makes the NA35 a great choice if some sunlight exposure is desired and privacy is not the primary concern.


The effect of any daytime privacy window film will greatly depend on the lighting conditions, because the side exposed to more light will become more reflective and harder to see through. This is why the privacy effect works so well during the day, since the sun usually makes the exterior of your building much, much brighter than the interior. The use of curtains or blinds will be needed for nighttime privacy.


Good for homes and office buildings that are directly exposed to the sun which is the source of UV rays, the NA35 window film provides an excellent UV blocking barrier. Being exposed to UV rays can cause skin problems such as premature aging skin and signs of wrinkles as well as eye problems. The NA35 film rejects about 99% of the UV rays, helping to reduce fading on your precious furniture and pictures.
