BDF Exterior film - EXNA40

Exterior Natural 40 Window Film is an exterior film that goes on the outside of the window, unlike traditional films that are applied on the interior side of the window. These films are made of high quality materials that are designed to weather the elements. The Exterior Natural 40 Window Film works to block heat before it even passes through your windows, which helps keep your home much cooler. The Exterior Natural 40 window film utilizes its medium visible light transmittance (40% = Medium) to reduce glare.

Since the film is exposed to the conditions outside, the edges of the installed film should be sealed with silicone window caulking after the film has fully dried.


Keep It Cool

The medium tint of the EXNA40 exterior window film gives it excellent heat rejecting properties that keeps your interior nice and cool while not being too dark, blocking about 56% of the total solar energy coming in from the sun. The number "40" in its name refers to the medium black tint that gives the window that traditional tinted look with lower reflectivity.

Shade with View

The EXNA40 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 EXNA40 provides an excellent view out the window with a mild level of view-shielding. This makes the EXNA40 a great choice if some sunlight exposure is desired and privacy is not the primary concern.

99% UV Rejection

Good for homes and office buildings that are directly exposed to the sun which is the source of UV rays, the EXNA40 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 EXNA40 film rejects about 99% of the UV rays, helping to reduce fading on your precious furniture and pictures.

For Dual Pane

The EXNA40 is the perfect solution for dual pane windows when properly installed on the outside of the window.


The exterior film blocks heat before it passes through your windows, resulting in less heat stored within the window compared to traditional window films that are applied on the inside.
