    What does ‘thermally broken’ mean?


    Thermally broken is a term to describe the insulation of a rooflight’s two metal halves to prevent cold escaping from the house, by combating aluminium’s heat conductive properties.

    The process works by including a high performance insulator material directly within the glazed unit of the rooflight. It is the only proven way to prevent a ‘cold bridge’, which is when humid air touches the cold surface of the aluminium frame and immediately turns into water droplets.

    Sunsquare’s thermal breaks


    Sunsquare’s fixed, walk-on and opening rooflights all feature polyamide insulating sections within the aluminium framework. These act as an effective barrier between internal and external temperatures, and are rolled together to create a strong and durable structure.


    Our rooflight frameworks also fill window cavities with argon gas to further improve internal insulation and reduce condensation. The frameworks are factory glazed with soft-coat low-emissivity insulating glass units which work by reflecting interior heat back into rooms below; helping property owners to reduce energy bills and the size of their carbon footprint.

    Benefits of thermal breaks


    • Reduces condensation and heat loss during colder months
    • Has a significant impact on the overall energy efficiency of the house
    • Ensures new-builds and redeveloped properties meet Part L Building Regulations, regarding fuel and power conservation and the Code for Sustainable Homes


    There are multiple considerations to think about if you want the perfectly performing skylight. However, we guarantee that with a properly installed skylight, the benefits more than pay for themselves! All of Sunsquare’s skylight products feature outstanding thermal performance. Find the rooflight that’s right for your property!
