Best airvents for bedrooms and living area?

[hannie0509]

I'm going to be fitting some air vents into 3 bedrooms and 1 living area this summer and was looking for the ones i need. I found these passive vents and was just asking if these would be OK?

Is it better to fit them high on the wall, or low??

Thanks

Best to explain why you are finding the need to fit the vents.

Not cheap, but you can buy passive air vents that have a flap that opens to let the air out (based on pressure differentials). From memory, when I last looked at one, in excess of 25 years ago, they were about £120.

I want to fit them just to provide a bit more air in the house. We currently have 1 in the bathroom and that's it.

Do you not have weep vents on the windows?

Air flow- yup, a good idea.

"Black hole" vents are good for bedrooms.
Due to the convoluted air path, you get ventilation, but less noise and draughts. A "hit and miss" grill on the inside, can also be used to completely block the vent in bad weather...
