Question:
Hi We live in an area prone to high winds. We'd like to get some way of allowing incoming gusts into our flat roof carport to escape so as to relieve the airpressure that forces up the roof in high gales eg storm Eunice. The carport is about 7 metres long by about 2.2m wide. We are thinking if we installesd say 6 of these vents, it would allow gusts to escape out of the enclosed space and so assist in reducing the impact of the wind. Any thoughts? MAny thanks Chris Miller, Minehead Somerset
Answer:
Good Morning Chris.
Yes, the OFT2 would help to relieve any air pressure. Please check that it is suitable for the materials on your roof first before placing an order.
