What is a walk-on rooflight?

A walk-on rooflight is a glazed rooflight specifically designed to support foot traffic while allowing natural light to pass into the room below. Unlike a standard rooflight, it is engineered with laminated structural glass and a reinforced frame to withstand loads that occur when people walk across it.

Walk-on rooflights are commonly used in roof terraces, basement conversions, courtyard gardens and other areas where glazing needs to form part of the walking surface.

How much weight can a walk-on rooflight support?

Walk-on rooflights are designed to support significantly greater loads than standard rooflights, but the exact load capacity depends on the size of the unit, glass specification, and intended application.

Load capacity is usually expressed as a safe working load per square metre, calculated to account for both foot traffic and any additional imposed loads such as furniture or planters. This figure will vary between manufacturers and products, so it's worth confirming the specific load rating with the supplier or structural engineer before finalising the design.

Are walk-on rooflights slippery when wet?

Walk-on rooflights can be specified with anti-slip finishes to improve grip underfoot, making them safer to use in external applications where the glass may become wet.

The level of slip resistance will depend on the glass finish and intended use. For areas with frequent foot traffic, it's worth specifying a higher slip-resistance rating from the outset.

Can walk-on rooflights be used outdoors as a balcony floor?

Yes, provided they have been specifically designed and specified for walk-on external use. Walk-on rooflights are commonly installed within roof terraces, balconies, and external decks to introduce natural light into the space below while creating a usable walking surface.

For external applications, drainage and slip resistance become particularly important, as the glass will be exposed to the elements year-round. The rooflight should also be designed to suit the structural loads expected for its specific location and use.

How thick is the glass in a walk-on rooflight?

There is no single standard glass thickness for a walk-on rooflight. The specification will vary depending on the size of the rooflight, the required load capacity and where it will be installed.

Most walk-on rooflights use multiple layers of toughened and laminated safety glass to achieve the required structural performance. The final glass build-up is determined by structural calculations and the manufacturer's specification for each individual project.
