Yes. QwickBuild is specifically designed for low-height and membrane / flat roof applications — one of its biggest advantages over timber. Using the A110 profile as both joist and beam gives a structural depth of just 45mm + 45mm, with supports starting from 3mm above the substrate. The full low-height range is 30–160mm (frame + supports, not including surface). The system is a floating installation that does not penetrate waterproof membranes — essential for balconies and rooftop terraces. It is approved for rooftop use up to 11m.
