GFRP monobloc upstands on corrugated roofing sheets GFRP monobloc upstands on corrugated roofing sheets 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. Suitable for pitched metal roofs, their external side is raw, grey coloured and treated with proper waterproofing special compound. The internal side is white painted and smoothed in order to get a better light diffusion. Dimensions Dome clear span A Metal sheet type Just like the other monobloc upstands, the various opening systems can be applied to get, in addition to a great light diffusion, even an optimal daily ventilation or a smoke and heat exhaust ventilation system. In order to avoid any infiltration, this kind of upstand must be installed on pitched roofs, where the slopes are useful to ensure water outflow. For particular requirements we realize upstands on client’s sample. Dimensions in cm. Every upstand can fit to our domes and opening device systems in order to get an excellent natural illumination, a great daily ventilation system and/or a smoke and heat exhaust ventilation system. Ogni basamento prefabbricato può ospitare tutti i modelli di cupola e i vari sistemi di apertura, ottenendo un eccellente illuminazione, una ventilazione giornaliera ottimale e/o un sistema di evacuazione fumo e calore.
