High performance outside blinds from Signature Blinds and Shutters, mounted to the outside of the glass, effectively regulate solar heat, light (glare) and UV (ultraviolet) to the glazed areas of homes and businesses ensuring a cool, comfortable and enjoyable indoor space. Creating a barrier in front of the glazing our external blinds block up to 97% of the suns solar heat energy, which in turn can reduce interior room temperatures by more than 10 degrees centigrade on even the hottest Summer days, keeping the indoor space naturally cooled and mitigating the use of air conditioning or cooling devices. And even better still when fitted with our exclusive Twilight fabric the view from inside to out is maintained.
