The windows are double glazed and in very good condition. However, the house is on the small size and windows tend to condense up.
Loft is insulated. I don't recognise any other insulation in the box room which has the air vent.
Thanks.
Yes, it allows the shutters to slide left and right (open and close). However, the draft through the vent is still quite strong.
I agree that condensation will be an issue since even with the air vent, the windows steam up every now and then.
What are the options in terms of blocking up...
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...
