Rated 5 out of 5Â by JVC600 AIR BRICK VENT
GOT THESE TO MODERNISE A HOUSE WITH OLD CLAY AIR BRICK FITTED.
THEY WORK WELL WITH THE TELESCOPIC UNDER FLOOR VENT.
NO ISSUES AND PRODUCT CORRECT SIZE FOR AIR BRICK , THEY ARE JUST SMALLER THAN THE LENGHT OF A STANDARD BRICK
MADE OF PLASTIC RATHER THAN CLAY I HOPE THEY WILL BE STRONGER AND LAST THE TIME .
THEY DO FEEL STRONG SO SHOULD BE FINE .
ITS A SHAME THEY ONLY DO THEM IN ONE COLUR VARIENT .

The Terracotta Air Bricks 9 x 3" are such value for money @ Â£1.69 it's a no brainer. They're easy to fit too as they are made of plastic they are able to flex slightly if the hole isn't exactly the right size.

I does exactly what you'd expect a product called an air brick to do, unless you were expecting to use it in combination with invisible mortar and build a see through house. It's a plastic brick that allows air through and did the job of providing ventilation to a bricked up chimney perfectly at a perfectly reasonable price.

These let a great deal more air through than clay - something like three or four times more if memory serves. They have downward angled slats to prevent rain getting in, so well designed too. And cheaper!!
