Ever wondered how insulation can carry structural loads without sacrificing thermal performance? In this video, we take a close look at high density reinforced polyurethane foam boards — demonstrating their closed-cell structure, compressive strength, and real-world use in cold store floors, loading docks, and insulated slabs. You'll see how these 30–150 mm panels handle foot traffic, screeds, and racking while keeping heat loss low, plus practical tips on cutting, jointing, and sealing for a reliable build-up. A clear, professional walkthrough for B2B specifiers and contractors.
