With glazing becoming a more prominent feature within building work, Surespan are increasingly being asked to provide specialist glazed access and ventilation solutions. One such instance was a recent project at Stratton House in London.
Bespoke Glazed Access
Surespan designed and manufactured a “bird wing” style, double leaf glazed ventilator with concealed operating gear from below. The operation of each leaf ensured maximum air flow into the building below and smoke release in the event of a fire. Measuring 2500 x 2000mm and polyester powder coated white to match existing building roof furniture.
Working closely with F2 Building Services Ltd who chose Surespan due to their expertise in producing bespoke products, the perfect solution to their ventilation requirement was produced.
Surespan is increasingly being asked to custom design access hatches to enable safe and easy access to all types of Biomass plants.
