Hi All,
We live in a 1930's semi-detached house with 3 bedrooms. The box room has an air vent around 20cm x 20cm with a grille on the outside and a plastic cover purchased from B&Q on the inside.
We are looking to permanently cover this air vent since it makes the room very cold.
What risks are involved if we cover this up? Also, what is the best way to do this? I guess expanding foam probably won't work for an air vent of this size.
Thank you in advance for any advice.
