Having problems from the sun shining through our front windows and heating the house we called Pelican Roller Shutters. Andy recommended we install shutters because of the thermal insulation properties they supplied. We were pleasantly surprised at the amount of heat they actually cut out.
My husband Rob is a shift worker so it is important that the bedroom remains dark and quiet thought the daytime. After we had shutters installed from Pelican Roller Shutters the bedroom is pitch dark, cool in summer, warm in winter and quiet despite the traffic.
