Insulating a suspended wooden floor

[BobbyBrown]

Hi everyone,

I'm renovating my front room (see my other posts) and I was recently under the crawlspace installing some electrics (1930's detached).

We've had one winter in the house and to be honest it was f****** cold. The front room is north facing and there are 5, large, airbricks for this room alone that supply air into the void beneath the floor. My oak floor simply lies on the joists and there is no other insulation stopping the cold air rising from the crawlspace.

Is there anything that can be done to insulate between the joists and still ensure the floor gets the required ventilation?

The air bricks are there to provide venting to the void, some would also escape up to help provide the air for an open coal fire. I presume you no longer have an open coal fire, so go ahead and insulate, and if your worried about venting the joists/floorboards once the insulation's in place, use a mineral insulation held in place from the underside with cheap garden neting stapled to the joist bottoms...pinenot

Thanks ill look into it. There's no longer an open fire but a wood burner is going to be installed next week (5kw). Do you know if it will make that much of a difference to insulate? It's quite a big and messy job and I'd like to know if its worth it before I start.

No not as far as the insulation goes, but I would check out the wood burner requirements. It should have a balanced flue which means it will draw its own air from outside and vent the exhaust gasses via the flue...pinenot
