Hi can anybody tell me a good vent to fit, and where to buy,
I've just knocked the hole through the gable end of my semi...the wind howls down in between my house and the neighbours on a windy day and I'd like to buy a decent vent cover that won't either flap about too much (I've heard that some can become like a whistle), it's to fit a 150mm dia duct
and would like one with a mesh to discourage insects getting in
any idea's folks?
I've looked on B & Q website and Wickes...
