Can i block and insulate an air vent?
This is my first winter in my new house and discovered a vent in the kitchen blocked off by the cupboards. The cold air coming in actually froze the cold water pipe. As it has already been blocked off (with what looks like a couple of tiles) is it safe to properly block and insulate it? There is a gas hob in there but no heating. Thanks
Air vents are installed for a reason. Often in older properties where condensation with single glazed windows were an issue, especially in kitchens and bathrooms, these provided the necessary ventilation.
These days double glazed units offer less vulnerability to condensation, however should have trickle vents ( a small manually operated vent at the top of a unit.)
As your vent has been blocked already, it should cause no real problem, however, do monitor condensation levels in the room as mould and fungus may result if improperly ventilated. Also consider the cheap solution of lagging the pipework in question, an easy DIY fix, available in all DIY stores.
Most importantly, if in doubt where gas appliances and ventilation are concerned, ask a qualified Gas Safe engineer every time.
Hope this helps
