3M™ Sun Control Window Film Prestige 40 Exterior Series

3M™ Sun Control Window Film Prestige 40 Exterior series (hereafter referred to as ‘3M Prestige 40 Exterior’) is a multilayer, metal free, spectrally selective, solar control film with a durable scratch resistant surface and a weather stable acrylic adhesive. 3M Prestige 40 Exterior is intended for exterior application on flat  glass substrates.

The film series provide the best balance between maximum light transmission and heat rejection. The nanotechnology significantly reduces heat while leaving the window appearance virtually unchanged. The films are designed for exterior use and they block up to 99.9% of damaging ultraviolet (UV) rays to reduce fading in interiors and furnishings. They keep homes and office buildings cool and comfortable in summer whilst ensuring minimal heat loss during the winter months. Their performance accelerates as the sun’s angle increases, which means the need for greater protection and comfort is met as required.

The film rejects up to 97% of the sun’s infrared light, up to 60% of the heat coming through your windows, and helps to provide energy savings by reducing the use of air conditioning. The films are free of metals and corrosion, and won’t interfere with mobile phone, GPS and satellite radio reception.
