Roof opening GFRP

for ventilation

Standard GFRP monobloc upstands are realized with glass fibre-reinforced polyester, white pigmented on the internal side. They are insulated with rigid expanded polyurethane panels, density 35±1 kg/m3. Thanks to their easy and quick installation and because of the great light diffusion given by the shape, prefabricated upstands are particularly suitable as an alternative to traditional concrete support walls, which are expensive and difficult to realize, especially if circular. They are impact resistant, weather resistant, dimensionally stable and designed to collect any condensation water. They are available in the dimensions and heights shown in the tables alongside.
