ventillation cavity - buying a property

Postby stone_arch » Fri Feb 04, 2011 10:01 pm

Hello everyone,

I am planning to purchase a property and have one concern. I am attaching the image of the property. The main rein size. The reception room of the property has a cavity hole on the front where there is ventillation vent installed. The hole runs from the vent to the internal wall of the house and is 6inch * 12inch.

I am worried that because of the hole there will be cold wind blowing in the room and thereby keeping heating bills high. There is a fireplace in the reception room but I dont intend to use it.

My question is can I block the hole with cement or other insulation material. Do i need any planning permission or freeholder approvals for this. All other houses in the road have no such visible vent.

I would appreciate expert opinions on the matter

Simply Build It

U can block the vent as long as fire is under 7KW and manufacturers state it doesn't need ventilation (regardless of whether ur going to use it) if it needs ventilation u should leave it, or change the fire to one that doesn't need ventilation

The vent will be for the fire, block the vent by all means but you will have to have the fire isolated/adapted so it cannot be used.

I have all original vents in my house - fully open. Nearly every other house in my street have had them removed/blocked. They provide fresh air to enter the room, and prevent stale air accumulating. It also prevents condensation, mould, unpleasant odours etc etc.

Fresh air is good for you, in a living area you want about 4 air changes per hour. I don't understand why people don't like fresh air in their homes, A human being needs 3000 cft of fresh air each hour.
