Why are Sunsquare skylights thermally broken?
As each rooflight is thermally broken, they help properties stay warmer, more energy efficient and, crucially in terms of skylight condensation, drier too . Thermal breaks prevent heat generated internally from transferring to external panes via direct transfer through the skylight’s framework. This allows the inner pane of a rooflight to stay as warm as possible, with minimal influence from the external pane that’s exposed to winter’s worst.
What is the insulation in roof lights?
The framework of our roof lights feature polyamide insulating sections within the aluminium framework which act as thermal breaks between internal and external temperatures – where the condensation could form. Building on this industry-leading innovation, we fill the window cavities with argon gas to ensure that the insulation properties of our skylights are the best that they can be.
