Hi all,
I have one customer moaning about the Building regs fan flaps keep going thunk at all hours, mostly its when gusting winds create a vortex a suck the flaps open then they shut again on the springs. I cannot think of an answer apart from him taking the flaps off after I have a photo of them installed, but then he will have drafts, any idea's.
Regards Steve
