More and more often existing buildings roofs have to be adjusted to current regulations, regarding smoke and heat exhaust ventilation systems (SHEVS). Old and new conception roofs, made with Onda Europa 177/51 curved or flat plate on “Y” beams, made it difficult to insert the smoke and heat exhaust ventilators, since there were no connection bases between the plate and the device.
CAODURO® has designed and built a series of prefabricated glass fibre-reinforced plastic (GFRP) and metallic upstands, both insulated with rigid polyurethane foam panels. Recommended for the higher light output and for the ease and speed of installation, GFRP and metallic upstands are an effective solution to the problem. By means of a targeted operation, the individual plates are replaced with prefabricated upstands which, being finished both internally and externally, do not require any additional treatment.
Another advantage is the possibility of installing on them electric daily ventilation devices, as well as the dual purpose SMOKE OUT®.
