I don't know of any deals, but would recommend CCF for bulk purchase.


Thanks for that. They don't show online prices do they?

I've picked up some bottom lay 100mm insulation to start the project. I picked it up from Wickes with a 20 off 100 spend. Possibly more expensive but it means I don't have 50 rolls of stuff knocking around while I clean out the old rubbish.

You'll have to phone/visit branch for prices.
Not the sort of place you go for a couple of rolls or boards, but usually cheaper than merchants on large purchases. Also got trucks with forklifts on if you ordering lots of boards.
Oh and there's Sheffield Insulation They got on-line prices.

air-seal first!


I'm not sure what you mean but you wouldn't seal an old loft. As Graham says, leave ventilation around the edge of the loft and lay a layer of insulation between the ceiling joists, then a layer at 90 on top of that. Put insulation on pipes, leave an uncoverd area under a tank and take care to not cover cabling to avoid overheating issues. The rafters would be ventilated from the gaps in or around the soffits..


I forget how differently our homes were built. By and large we don't have any plumbing in attic spaces.

I meant to air seal the living space from the attic space, the attic space should still be well ventilated, and is often times benefitted by increasing the ventilation. Spray foam, or at least caulking around ceiling panel joints, around the top plate of the house, around any intrusions through the ceiling panel. etc.... that's what I meant by air sealing before putting down the new insulation.

Here's a nice diagram showing the jist of what I'm saying

I need to clean out the old insulation in a loft and insulate it from scratch.

Firstly, I don't suppose anyone is aware of any deals at the moment? You used to be able to pick up loft insulation for a 1 a roll but those deals are long gone. Not being on benefits and having some insulation seems to rule me out of anything I can find.

Secondly, is there anything special I should be looking for? The cheapest options seem to be the recycled glass or plain glass mineral wool.

Prices seem to be 20 for around 5.5 SQM @ 20 cm thick.

They're talking as if the deals are back on, maybe.

Thanks for the link Nick but I still fail on the following "You have existing loft insulation more than 50mm thick, covering more than a third of the loft. "

The good news is the Wickes insulation I mentioned to is now buy 2 rolls for 30 and they currently have a spend 100 get 20 off reusable offer, so I've got another car load at the reduced price and another 40 off. Thankfully I have a roomy gas guzzling 4x4 to get it all in.

hope your vacuum cleaner has a long lead,i found out the hard way that the wrapping on insulation might be ok on your rolls but if one split beforehand it sticks to the outside of the packaging until it meets a car seat.

You haven't seen the car, I use dust covers to keep things clean when I put them in the car, not to keep the car clean.
