From what is Window Film made?

Different polyesters are transformed during the manufacturing process to produce a thin, transparent film that adheres to glass when a pressure sensitive or a CDF (Clear, Distortion Free) adhesive is activated by a mild solution of dishwashing detergent and water.

Window film is micro thin, composed of polyester and metallized coatings bonded by adhesives. It is installed onto glass surfaces to provide significant solar protection. It screens out heat, blocks out 99% of the sun's damaging ultraviolet rays and harsh, uncomfortable glare deflects while allowing glare-controlled sunlight to pass through. By adapting to changes of season, (reflecting the hot sun in the summer, and, with Low E film, reradiating heat in the winter) it helps keep you comfortable all year long.

Do you install window film on the inside or outside of a building?

Window film is typically installed on the interior side of a window. As it is a finished product, is best installed after all other nearby construction is complete. If access to the interior side of the window is difficult to obtain, an exterior application can be performed.

Will my energy costs decrease?

Absolutely! The amount of money saved depends upon the type of film chosen and certain property-specific variables (location, climate, existing energy costs, HVAC system, etc…). After obtaining some basic energy unit costs for a given building (minimum of 5,000 square feet of glass), we will conduct an Energy Audit to estimate the annual dollars saved by different film types.

Will my furniture fade be reduced?

Yes! Furniture and fabric fade is partially caused by the sun’s ultraviolet rays. All SunPro installed window films block out 98% - 99% of UV light.

How do I clean the filmed surface after installation?

Window films may be washed with common washing solutions (including ammonia-based products) thirty days after installation. Abrasive cleaning agents and bristle brushes (that would scratch the film) cannot be used. Synthetic sponges, squeegees, or soft cloths are recommended in addition to the cleaning solution. To maintain your warranty, do not use tape or other adhesive products on the film.
