How do roller blinds prevent heat loss?

Roller blinds are filled with polyurethane foam, the same insulation material used in refrigerators and freezers. This efficient thermal insulation layer allows roller blinds to prevent up to 90% of the heat from being lost through the windows!

Rolling shutters are installed outside the windows, and when completely closed, they completely cover the glass. This forms an extremely effective insulation layer that prevents hot air from the house heating from escaping through the windows.

By greatly reducing heat loss, roller blinds will help save 30-40% of the energy costs of heating houses. Reducing the use of fuel and natural gas is also a positive step towards a cleaner environment.
