A clever piece of equipment but does not cater for unplastered walls as the minimum size it can be reduced to is a 'plastered wail' length to longI got over the problem by angle grinding the plastic air brick in half

I like this product because it's easy to use adjusts to most walls and can always use a hacksaw if need be to trim down

### ⭐⭐⭐⭐ 4.0 out of 5 stars







  
  
    Hopefully will make the house a bit less draughty this winter
  

*by S***S on Reviewed in the United Kingdom on 5 October 2014*

Stops the wind whistling in directly through the air brick - it also stops the light coming in and reduces noise from the road a little. It only gets 4 stars as I fitted it myself and wished afterwards that I'd paid someone else to do it as it involved laying on the floor with a big hammer and a brick bolster chipping bits of brick out so the ventilator would fit.
