SDL Atrium

Its steel-reinforced sections form either a single pitch or apex roof, and built-in roof ventilation maintains a comfortable and pleasant environment.

Atrium is a thermally unbroken roofing system for glass extensions. Combined with turn & slide, bifolding or sliding door systems and a choice of rooflight design, it offers you protection from the elements, forming a glass oasis to open up on sunny days.
