Are Security Shutters energy efficient?
A. Yes. Independent tests have proven that Enviroblind Rolling Security Shutters reduce energy loss through unprotected glass in windows and doors. In fact, when the Security Blinds are closed they can increase the insulation value of glass in windows and doors from R 2.1 to R 4.5. Translate this R 2.4 increase in insulation efficiency into energy and financial savings, and it becomes clear why more and more schools are including Roll Down Shutters in their energy savings plans.
