Basement Walk on Glass Rooflights & Lightwells
LARGE WALK ON ROOFLIGHT OVER BASEMENT, LONDON
The walk on rooflight comprises a multi-layered laminated glass assembly bonded with structural interlayers to form a monolithic structural pane. The top layer — the triple-laminated glass — is specifically designed to resist imposed loads and dynamic impact.
Below this, the triple-glazed configuration incorporates two additional glass layers separated by argon-filled cavities. This structure provides exceptional thermal insulation, reducing heat loss through the glazing and preventing cold bridging between the patio and the interior basement environment.
Rooflights in Basement Conversions: Bringing Light Underground
Basement conversions are a popular way to create extra living space, particularly in urban areas where above-ground extensions may be restricted. One of the greatest challenges with below-ground design is overcoming the lack of natural light. This is where rooflights play a vital role — transforming dark basements into bright, welcoming, and energy-efficient spaces.
Why Rooflights Matter in Basement Design?
Natural light has a powerful effect on how a room feels. Without it, basements risk being perceived as enclosed, damp, or purely functional. By introducing rooflights, architects can:
-
Maximise daylight penetration, reducing reliance on artificial lighting.
-
Improve ventilation, particularly with opening rooflight systems.
-
Enhance property value, as brighter basements are more desirable for living or working.
-
Create a sense of connection between underground rooms and outside spaces.

Standard Specification
20 Year Laminate Seal Warranty
Each walk on glass rooflight is constructed from triple-laminated, triple-glazed safety glass, engineered to withstand walk-on loads. The system comprises:
| Top Layer | Triple-laminated structural glass — three sheets of toughened heat-strengthened glass bonded with structural interlayers such as SentryGlas® or PVB for enhanced rigidity and residual strength. |
| Middle & Bottom Layers | A sealed triple-glazed insulating glass unit (IGU) incorporating Low-E coatings, argon gas filling, and warm-edge spacers to ensure optimum energy performance. |
| Support System | A discreet thermally broken frame fabricated from stainless steel or aluminium alloy, fully integrated into the surrounding waterproofing membrane. |
This configuration produces an exceptionally strong yet thermally efficient rooflight capable of achieving U-values as low as 0.9 W/m²·K, while maintaining transparency and optical purity.
Drainage, Sealing & Weatherproofing
A critical aspect of rooflight performance is the integration of effective drainage and waterproofing systems. Walk-on units are typically installed flush with surrounding paving on a recessed support frame incorporating:
-
Perimeter drainage channels to manage runoff and prevent water pooling.
-
EPDM or butyl compression seals ensuring long-term air and water tightness.
-
Thermally broken upstands to prevent cold bridging between structural layers.
The frame interfaces with the roof’s waterproof membrane, creating a continuous, weatherproof envelope between patio and interior. Periodic maintenance ensures drainage outlets remain free from debris.
Multi panel Walk on Glass Rooflights
WALK ON GLASS ROOFLIGHT ON BALCONY – OPAQUE GLASS – MULTIPLE PANEL CONFIGURATION
Glass units are delivered pre-fabricated and lifted into position using vacuum lifting equipment to avoid edge damage. The joints between units are sealed using UV-resistant structural silicone, producing a seamless appearance that allows the glass to visually merge with surrounding hard landscaping.
Walk On Glass Rooflights on Balconies: Strength, Safety & Light
Balconies are an extension of living spaces, offering outdoor access and natural views. When combined with walk-on rooflights, they provide a dual function: a usable surface above and a source of daylight below. This solution is particularly popular in multi-storey developments, basement extensions, and luxury homes.
I would highly recommend Structural glass design. Many thanks for all your help with my walk on rooflights.

CURVED CLARITY: OVAL SHAPED TRIPLE GLAZED WALK-ON GLASS ROOFLIGHTS FOR SUBTERRANEAN SPACES
As architecture continues to embrace light as a building material, innovations in structural glazing have allowed designers to merge daylight, form, and function in remarkable ways. One such innovation is the oval-shaped triple-glazed walk-on rooflight — an elegant solution that combines advanced engineering with sculptural design.
Installed within patios above sub-ground rooms, these bespoke rooflights introduce daylight into spaces once confined to artificial illumination, without compromising the usability or aesthetic of the surface above. Their oval geometry softens architectural lines, creating a fluid dialogue between landscape and structure.
Professional Installation
Our experienced team will ensure a perfect fit and finish utilising our advanced lifting equipment. We can facilitate road closures and obtain necessary permits if required.
Aftercare and Support
Our comprehensive support includes an impressive 10 year warranty on the laminate seal of your glass, along with a 10 year warranty that covers the other materials utilized.

FEATURED PROJECT: Citadella, Gozo, Malta
UNESCO World Heritage Site
At the Citadella in Gozo, Malta—a designated UNESCO World Heritage Site—a series of walk-on and drive-on structural glass floors and rooflights were installed as part of a sensitive restoration project. The glass installations were designed to integrate seamlessly within the historic stone architecture, allowing visitors to experience the ancient fortifications while preserving the integrity of the original fabric.
Each panel comprised quadruple-laminated, toughened structural glass with a non-slip finish, engineered to support both pedestrian and vehicular loads without compromising transparency or safety. Beneath the walk-on glass, the subterranean exhibition spaces below were visible, enhancing the visitor experience while maintaining controlled internal environments. All fixings and support structures were fabricated in marine-grade stainless steel, ensuring long-term durability in the Mediterranean climate.
The installation represents a precise balance between heritage conservation and contemporary engineering, demonstrating how modern structural glass technology can be employed to celebrate and protect historic environments.
