Can I use Nansulate® on Windows to control heat transfer?
Nansulate® can be used on glass to help insulate, but we do not recommend it on window glass, because it will cause the appearance to be slightly cloudy after application. It is very effective in daylighting and skylight applications to control heat transfer while still allowing in difused light. When applying to glass, allow at least 30 days before being subject to rain or condensation.
