xpelair - outside cover banging

[Explorer-8]

I've got a new xpelair with a circular air vent through the bricks to the outside. The plastic cover fitted on the outside wall is designed to keep dust, birds and insects out, but when the weather is windy, the plastic flaps make a loud banging noise as they open and close. Is it possible to fit anything on the outside of that cover to act as a wind break? I've had a search on-line, but I can't find anything.

just stick a little rubber stop on the inside of the flap to deaden the sound

I 'weighted' mine down a bit by drilling a hole in it towards the bottom and attaching a large bolt and nut. Works a treat and doesn't look unsightly.

Last year I fitted a new vent for an extractor hood, it had flaps which kept banging when the wind blew. After a few weeks it was really annoying me ... so I fitted one of these ...

Following on from what Williwonker said, I reckon that a strip of the sponge rubber draft excluder material would stop the noise if it was stuck on the outer face of all the flaps so that it supported the bottom edge of the flap above it. In this position on the top of the flap it wouldn't interfere with the air flow or collect any excess dust.

That may be fine in the summer ... wait until the winter winds are blowing through your partially open vent ..!

Thanks for the replies. I'll ask the builder who fitted it to try one of these remedies.
