Framed or Frameless Walk On Roof Lights
Our Walk On Roof Lights are available in a range of sizes and configurations to suit your needs. The first choice you have is wether to choose a framed or frameless option. The glass structure is actually the same for both options, the only difference is how you wish to fit the walkon roof light.

Walk On Roof Lights Built For Safety, Style, and Everyday Living
Elevate your space with premium walk on roof lights engineered for strength, thermal performance, and a minimalist aesthetic. Whether you are creating a dramatic glass floor between internal levels or bringing natural daylight into a roof terrace, our walk-on rooflights are designed to perform in real conditions and look beautiful for years. Every unit is crafted from multiple laminated panes for load-bearing safety, with precise edge detailing that delivers a clean, contemporary finish.
Choose from frameless or framed configurations to suit your project and budget. The frameless option gives you that seamless edge-to-edge glass look at the lowest price point, while the framed option provides a classic upstand detail. For external roofs, select our thermally broken build that adds an additional pane and an argon-filled cavity to improve insulation and reduce heat loss. For internal floors and galleries, the non-thermally broken build offers unbeatable value while maintaining excellent clarity and strength.

A walk on rooflight is one of the most effective ways to transform a dark area into a bright, welcoming space. By introducing daylight from above, you reduce reliance on artificial lighting during the day, create a stronger sense of connection between floors, and add a striking architectural feature that feels both luxurious and practical. The result is a more valuable, more enjoyable space that looks great from every angle—above and below.
Installation is straightforward and supported by clear technical literature. The frameless build sits cleanly over your prepared opening, while the framed option uses an upstand detail many contractors know well. Our downloadable specification sheets outline the glass build-up, dimensions, and best-practice installation notes so your team can plan with confidence.

Walk-on rooflight FAQs
Can these really be walked on?
Yes. Every walk-on rooflight uses structurally rated glass tested to load-bearing standards, so it's safe to walk across — ideal for roof terraces, balconies, glass floors and internal walkways.
Frameless or framed — which walk-on should I choose?
Frameless walk-on glass gives the cleanest, most minimal finish flush with the surface. Framed adds a defined, thermally broken edge for the best energy performance. Both are made to measure and fully load-rated.
Do you offer an anti-slip finish?
Yes. We recommend an anti-slip finish for any external terrace or surface that may get wet. Clear and opaque options are also available depending on the privacy and light you need.
Where are walk-on rooflights used?
They're perfect for roof terraces and balconies, glass floors and landings, basement light wells, and anywhere you want to bring daylight down through the floor above.
What sizes can you make?
Made to order to the millimetre, within the structural spans for walk-on glass. Enter your sizes above for an instant price, or call us to check a specific span.
