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 angleâabove 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.
