Solar Gard® Sentinel Outside Weatherable Films
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 OSW films carry a limited warranty, as external applications, by nature, are subject to an array of unpredictable weather and atmospheric conditions.
For more information, contact your local Solar Gard representative.
