    Outstanding
    Thermal Performance

    As pioneers in the UK rooflight industry, Sunsquare products are designed and manufactured to provide outstanding thermal performance alongside their stunning aesthetic qualities. Our roof windows are made from our extruded aluminium profile which is thermally broken using multiple polyamide insulating sections. It’s therefore easy to understand why our entire BSI Kitemarked product range surpasses Building Regulations with ease, keeping homes and workplaces at comfortable temperatures, day and night.

    Laminated
    Inner Panes

    Sunsquare rooflights are regularly specified due to their outstanding levels of performance and safety that comfortably surpass Building Regulations. With laminated inner panes as standard, our technical partners know that in the unlikely event of product damage, the broken glass will be fully contained within the laminate, protecting those enjoying abundant natural light below.
