Opalux® Matt Silver films are used to give two-way privacy without seriously reducing the natural light level, whilst offering maximum heat rejection. It is of particular use in combating severe solar heat gains and glare problems. The combined solar privacy film can also provide additional benefits such as, uniform outside appearance, winter heating savings, and as with most Opalux films up to 99% ultraviolet light (UV) filtering. (For specialist UV filtering in museums etc, see specialist UV Control Film).

The films are applied internally and, in daytime, lend the glass a silver reflective outside appearance, whilst from the inside, the visual effect, is a silver frosted matt.
