These upstands are realized with Onda Europa profile 177/51 cm pitch.
The easy installation and the limited intervention area make them particularly suitable to be placed in corrugated roofing sheets.
They are realized with a 20 or 25 cm height and their structure is very similar to standard GFRP upstands.
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.
