Walk-On Rooflight Overview
Whether you’re working on a high end home renovation or a commercial build, walk-on glass offers a smart, architectural solution for introducing light to lower floors.
Our Walk-On Rooflights and Structural Glass Floors are engineered to safely support foot traffic, public use, and even vehicle loads depending on the specification.
They allow daylight to flow into lower levels, transforming underlit basements, stairwells, and voids into bright, usable spaces.

Rooflight Specification
25.5mm Specification
25mm Outer Pane
-
Uniformly Distributed Load (UDL): Maximum of 1.5 kN/m².
-
Concentrated Load: Maximum load of 2.0 kN
-
Maximum Size: The 25mm glass is limited to a maximum length of 2000mm and maximum width of 1000mm. The total surface area must not exceed 1.5m².
-
Use Case: Ideal for applications with light foot traffic and low load-bearing requirements, such as residential spaces or smaller internal walkways.
This thickness offers good strength and thermal efficiency for more lightweight applications but is not suitable for heavier traffic or large-scale commercial areas
33mm Specification
33mm Outer Pane
-
A standard range option, offering enhanced strength for areas subject to more foot traffic.
-
Slightly thicker than 25mm, providing added impact resistance while maintaining clear aesthetics.
-
Suitable for garden terraces, balcony rooflight, glass bridges with light foot traffic or gathering over basements, or smaller walkways.
-
Retains high thermal efficiency and safety standards, ensuring long-term performance.
48mm Specification
48mm Outer Pane
-
Uniformly Distributed Load (UDL): Suitable for up to 5.0 kN/m² and higher, depending on build-up.
-
Concentrated Load: Typically rated to withstand 4.5–5.0 kN
-
Recommended Use: Ideal for public spaces, educational facilities, showrooms, and light vehicle-accessible areas such as maintenance routes or internal courtyards.
-
Application: Engineered for environments with higher footfall, occasional vehicular access, and greater safety requirements. Suitable for structural glazing installations requiring larger spans or additional strength.
82mm Specification
82mm Glass
-
The thickest and most robust option, designed for heavy duty, high-load applications.
-
Ideal for areas where vehicle traffic (such as vans or light trucks) or even heavy machinery may drive over the rooflight or floor.
-
Provides exceptional impact resistance, thermal insulation, and UV protection, ensuring maximum durability and safety even under extreme conditions.
-
Commonly used for driveways, parking areas, or larger commercial projects where strength and longevity are paramount.

Why Choose Walk-On Rooflights or Glass Floors?
Whether you’re converting a basement into a kitchen, covering a swimming pool, or bringing natural light into a dark internal space, walk-on glass provides a clean, modern way to open up your design without compromising on usability or safety.
By replacing solid flooring with structural glazing, you introduce daylight deep into the property, turning underused or light starved spaces into warm, liveable areas. It’s especially effective in new builds where creating flow between upper and lower levels is key to the experience of the home or building.
- Maximise Natural Light
Install above basements, stairwells, or dark rooms to introduce daylight without compromising usable floor space. - Space-Efficient Design
Create multi-level visual flow and connectivity without bulky structures. - Indoor or Outdoor Use
Ideal for roof terraces, internal glass bridges, mezzanine floors, or even garden paths
Frequently asked questions
Do you offer a site survey before installation?
Yes, we provide site surveys for more complex or custom installations to ensure accurate measurements and assess structural conditions. This helps us deliver a perfect fit and smooth installation process.
What information do you need to provide a quote?
To provide an accurate quote, we typically need the approximate dimensions, roof type (flat or pitched), preferred glass specification, and project location. Photos or drawings are helpful too.
What are the lead times for manufacturing and delivery?
Lead times vary depending on the complexity of the rooflight, but standard units typically have a lead time of 3–4 weeks. Custom or oversized units may take slightly longer.
Can you help with planning or structural requirements?
While we don’t manage formal planning applications, our technical team can provide detailed information on glass load, unit weight, and recommended fixing methods. This helps architects, builders, and engineers specify the correct structural support for our rooflights.
