Load-rated walk-on glass

Daylight below, usable floor above — made for everyday use

Installed flush with your external flooring, our walk-on rooflights turn a terrace or flat roof into a light source for the space beneath, with a frameless internal design that gives a 100% clear opening.

Benefits

Built for terraces and flat rooftops

Designed, fabricated and installed by one team from our Wembley workshop — so the detail you sign off is the detail that gets fitted.

Clear estimated lead time

Walk-on glass rooflights take 3–4 weeks once final measurements, specification and deposit are confirmed.

Rated for real use

Domestic loading of 1.5kN/m² UDL and 2.0kN concentrated; commercial loading of 4.0kN/m² UDL and 3.6kN concentrated.

Nothing in the way from below

The frameless internal design gives a 100% clear opening, so the room beneath sees glass, not frame.

Sits flush with your floor

Installed level with the external flooring, so the terrace stays a terrace with no trip hazard.

Safe underfoot in the wet

Anti-slip and obscured finishes are available for exposed or overlooked positions.

Thermally broken frame

Thermal aluminium frame powder coated Anthracite Grey RAL 7016 as standard.

Lead times and larger bespoke sizes

Standard rooflights: approximately 2–3 weeks. Walk-on glass: approximately 3–4 weeks. Large or jumbo rooflights: approximately 5–6 weeks. Examples of larger bespoke sizes include 3000 × 2000mm, 3000 × 3000mm, 3000 × 5900mm. Large and jumbo rooflights are assessed individually because lead time depends on the overall dimensions, glass specification, weight, number of panels, framing system and installation requirements. Lead times begin once final measurements, specification and deposit are confirmed. We’ll confirm the delivery or installation date with your quotation.
