    What makes a skylight “fire-rated”? 


    Fire-rated skylights contain glass that has been proven to provide a period of protection against fire during a Fire Resistance Test. The glass must contain a fire within a given period to pass this test. At Sunsquare, we currently offer either 30 or 60-minute ratings.

    Fire-rated glass is a requirement on any rooflight in an area that is part of a fire escape, in line with current building regulations.


     The glass sits on a subframe below the skylight, completely out of sight. You can’t tell the difference to the naked eye, but it ticks all the boxes for building control.

    Installation of a fire-rated skylight

    After deciding that your property needs a fire-rated skylight, the first step is to source a contractor, architect and roof light manufacturer that you feel will suitably protect your home. 

    Your architect should outline where your skylight will be best placed and what regulations must be considered when making changes to your home. For more information on regulations that could influence your project check out our blog post, ‘Roof windows and planning permission: the ins and outs.’ 


    Once you have a detailed plan of your new skylight and decide which rooflight is best for you (you can do this by speaking to one of our team), a contractor can prepare the opening for the skylight for installation. Please note that after our installation of the product, the frame requires fire retardant plasterboard cladding by the contractor.

    What are the options for fire-rated skylights? 

    Alongside our extensive range of sizes and shapes of standard skylights, our fire-rated skylights can also be integrated with a variety of upgrades to level up your home or office building. 

    Walk-on skylights

    Using the very latest glass technology as well as a unique internal fire frame, Sunsquare interior walk-on glass floorlights are designed to fit flush with the floor, so you maintain full function of the floor while the space below is illuminated with natural light.

    Optional anti-slip treatments available


    At Sunsquare we understand that interior glass floors must be both practical and aesthetically pleasing. That’s why we offer clients the option to add an anti-slip treatment to the product. Our floorlights are perfect in busy living areas such as kitchens and bathrooms, where they are more likely to get wet, as our anti-slip specification can provide the ultimate safety and style.

    Available in multiple configurations


    Whether it’s a stock size or made-to-measure multi-pane rooflight, we can provide you with a design to meet your individual requirements. No matter how unique the project, Sunsquare can help you to find the perfect product for you and your budget.

    Outstanding thermal and practical performance


    Sunsquare’s own extruded aluminium profile is thermally broken using two polyamide insulating sections and is factory-glazed with a 24mm argon-filled and soft coast low-E insulating glass unit. All external glass edges are also protected by polyester powder flashings.


    A laminated inner pane is fitted as standard in Sunsquare skylights. This provides a safer and more secure rooflight with the added benefit of filtering out 99% of the sun’s harmful UV rays.

    Why choose Sunsquare for your fire-rated skylight?


    Our interior floorlights are the only internal glass floor panels which surpass the BSI’s rigorous Kitemark standards.
