Can I use this to cover some windows?


Best use shade-cloth roll-ups outside window to reduce heat-gain. Can make airspace w/circulation between glass & Reflectix inside, by mount Reflectix to 1x2 frame, hung on surrounding wall surface inside. Depends if main goal is as a light, or heat block. Or hang as curtain panel hidden by fabric panel.

We do not recommend using Reflectix as a window application. Our product reflects the radiant energy at such a high rate of intensity that it can cause a window to crack or even shatter.
