Duplus Walk On Rooflights

Our walk on rooflights are designed to be flush with surrounding flooring, typically on roof terraces with decking. An ideal ‘walkable’ solution to allow natural light to flow into the room below, without sacrificing the useable space above.

Duplus walk-on skylights have incredible load-bearing properties satisfying the latest Part Q building regulation requirements, anti-slip options and a layer of toughened laminated glass up to 33.5mm thick to withstand foot traffic.

Combine these great features with a contemporary aesthetic, powder-coated matt black frame, exceptional build quality in our UK factory and a 10 year guarantee to ensure complete satisfaction in your purchase.

Building Regulations & Compliance

Part Q (Secure by Design) compliant as standard. Walk-on glass rooflights are suitable for flat roof residential properties. They have been designed to meet the imposed load requirements of BS EN 1991 Subcategories A1, A2, A3 and A5. This means that they are capable of withstanding a uniform distributed load (UDL) of 2.5kN/m² and a concentrated load of 2.0kN. Note, for new projects started after 1st

Note: October 2013, walk on rooflights stating only compliance to the lower loads defined by BS6399 (1.5kN/m² UDL and 1.4kN concentrated load) should be avoided.

Secure by Design (Part Q) enhanced security compliant as standard.

Advanced Features

The extruded aluminium perimeter frame is powder-coated RAL 9005 black matt as standard. Other RAL colour options are available upon request.

Avant-Garde or sandblasted anti-slip external glass treatments to BS7976-2 are available upon request, to reduce the risk of slippage.

Delivered FULLY ASSEMBLED. No need for time-consuming assembly on-site, lowering your overall costs. Significantly higher security compared to kit systems.



The maximum size for our walk-on rooflights is 1.1m x 3m external kerb size.

Yes, we provide a glass option with etching on the surface of the glass to reduce slip. There is an additional cost for this feature. This is calculated on the size of the rooflight required.

No, our walk-on rooflights are single, individual units with a single opening and a maximum size of 1.1m x 3m.

Unfortunately we are unable to provide connected walk-on rooflights or a kit to achieve this.



A builders kerb is required for installation. The roofight should be fitted first, with the surrounding flooring completed afterward enabling an overall flush finish to be achieved. It is essential that the correct loading standards are considered, reference should be made to Eurocodes BS EN 1991.

Material Specifications & U-Value

Following extensive structural glass calculations, our rooflights incorporate an external pane of toughened laminated glass. This varies between 25.5mm and 33.5mm thick, depending on the size of the walk-on unit selected.

Duplus rooflights achieve outstanding thermal performance. True U-value and Ud-value available upon request.
