Solar Gard® Sentinel™ Outside Weatherable Films

Solar Gard Window Film keeps heat where you want it.

Low-E glass with outside weatherable film provides protection from heat loss and from solar radiation.

Solar Gard® Sentinel™ is a range of Outside Weatherable (OSW) films that are ideal for buildings that have low-E, laminated or wired glass.

The Solar Gard Sentinel OSW family features the following products:

Silver 20 and 35
Stainless Steel 15, 25, 40, and 45
Solar Bronze 20, 30 and 40
4 Mil Clear

Sentinel OSW films are designed to be an external sentry for buildings, protecting them from high levels of heat, glare, and UV.

For opportunities where the risks of glass breakage and/or seal failure are too high, or where accessibility to the interior is unavailable, OSW films provide the perfect solution.

Solar Gard Sentinel OSW films carry a limited five year vertical and three year horizontal warranty, as external applications, by nature, are subject to an array of unpredictable weather and atmospheric conditions.
