alwitra kerbs for sophisticated daylighting
Put an end to the rooflight’s second role as a thermal bridge! alwitra kerbs for flat roofs provide for sophisticated daylighting and excellent thermal insulation. Made of extruded polyvinyl chloride plastic profiles, alwitra rooflight upstands feature excellent impact-resistance of the frame, an innovative cellular system, and ensure reliable flashing against PVC, bitumen, and high-polymer waterproofing membranes, for new build and refurbishment.
