Roof glazing

Introduce natural light into the core of a building

There is nothing like a glass roof to create a sense of wonder, space, light and an organic connection with the outdoors all inside one building. Using roof glazing throughout a building also can reduce the need for artificial lighting by scattering natural daylight throughout the core of a building, energize work and public spaces, and create a truly unique, bright interior.

How to achieve a glass roof

Depending on the type of building, architects and designers need to consider relevant international and/or local glazing standards relating to roof glazing. These typically address the various building types, classifying them into different load levels and providing guidance on maximum allowable deflections and stresses for overhead glazing. The thickness of the glass and the integrity of the insulating glass unit therefore must be considered. The Guardian Glass team and supplier partners are available to help you navigate these considerations.

The support system for the glass needs to be strong enough to prevent distortion under load. Unlike vertical glazing, maintenance, water and the dead load (the weight of the glass itself as a permanent load) need to be considered. If the glass roof forms part of an accessible area, it must be treated as a glass floor. Laminated safety glass is often recommended for roof glazing, although toughened glass is sufficient for some overhead glazing applications.
