St Andrews Square

Bespoke 5° Mono-Pitch Rooflight | Lonsdale TG50 Glazing System

Rooflights & Atriums Ltd were appointed to deliver a bespoke architectural roof glazing installation at St Andrew Square in the heart of Edinburgh, incorporating a contemporary 5-degree mono-pitched rooflight utilising the Lonsdale TG50 thermally broken aluminium glazing system.

The project involved the design, supply and installation of a low-pitched glazed roof structure, carefully engineered to maximise natural daylight while maintaining a clean, understated architectural appearance sympathetic to its prestigious city-centre surroundings.

The shallow 5-degree roof pitch presented particular technical considerations, requiring careful attention to glazing design, water management, drainage and weatherproofing to ensure reliable long-term performance. The Lonsdale TG50 system provided a versatile solution, combining slimline aluminium glazing profiles with modern thermal performance and architectural detailing.

Particular emphasis was placed on the integration of the rooflight with the surrounding building structure, ensuring that perimeter interfaces, glazing supports and weatherproofing details were carefully coordinated to achieve a robust and visually refined installation.

The completed rooflight provides an elegant overhead glazing solution, introducing natural daylight into the building while complementing its wider architectural design.

The project demonstrates Rooflights & Atriums Ltd's expertise in bespoke low-pitch roof glazing, combining specialist technical design, precision detailing and skilled installation to deliver high-performance architectural glazing solutions in challenging building environments.
