Xtrm SkyLite Window Film 

The SolarZone Xtra range of window films are special versions of many of our standard SolarZone window films, developed for installation on the exterior of the window, instead of on the interior (room side) of the glass.  Exterior films reject solar energy on the outer pane, keeping the inner pane cool and reducing the energy that penetrates inside even more effectively than a similar interior film.   SolarZone Xtra offers one of the best solutions for keeping interiors cooler in the summer, maximizing savings on energy costs, and upgrading energy efficiency.

We’ve developed our SolarZone Xtra exterior films to bring exceptional energy efficiency to almost all glazing types, and to complement many types of Low-E glass, providing summertime cooling without affecting the wintertime insulation efficiency of Low-E coatings.
