One from the 'grapevine' - half price loft insulation from Friday 4th Nov. Will be on for a couple of days, maybe more. Should be online and in store.

Good deal if you can't get your energy company to sub the cost - which usually involves a 6 month wait.
If you do double up, just make sure you lay the second layer at a right angle to the first, and check for condensation after you've laid it.
If you have a cold tank in the loft, make sure you insulate it and lag the pipes appropriately, otherwise, BIG costs. Often better to leave directly under the tank uninsulated - if you can't find a suitable solution.

Check with your local council you may be able to get a grant for 75% of the cost ( i used to sell loft insulation and other energy products years ago) buy some paper overalls as this stuff itches like the clappers

break building regs, that made me laugh, even a Victorian house should not be using kingspan or celotex between the floor joists, you should use natural materials, like hemp or lambswool.

any use for basement between the floor joists?

Unless you have a newer house (in which case you shouldn't need more insulation anyway) do not do that with standard insulation.
Causes damp problems. You need to use a specific floor insulation (kingspan is the one I remember but there's a couple), designed for underfloor use, they insulate but don't get anywhere near as bad an issue with damp.
By using inappropriate damp-proofing on main joists you can actually break building regs & invalidate insurance.
I only know this cos my father in law suggested doing it in our victorian house so did some research & found a few horror stories & as such the correct way of doing it.
Unfortunately the correct way is more expensive, but as opposed to potentially causing rot of your floor support joists, not so much in the long term!

can anyone tell me what the recommended depth for loft insulation is? I have just bought an old house and the surveyor mentioned it only has between 50 - 100 mm.
chelseablue to t8m

building regulations state a depth of 270mm, but that is for new build properties, but 200mm will achieve a U value of 0.20W/m2.

Unless you love the external walls look , see about insulating the external walls.Insulating the loft is the cheapest way to go but seen some lovely insulated and rendered walls lately ... http://www.energysavingtrust.org.uk/home-insulation/solid-wall

This is slightly cold if this is the 100mm depth version, which I suspect for the price it is. I've been looking at more loft insulation and would go for the 200mm as I'm sure if you buy five or more with B&q it's costs about £16 per roll.
chelseablue to Iamthebargainhunter008

the 200mm version is £20 a roll if you bought 5 or more, works out at £3.63 a Sq metre,
the 100mm version at £9 a roll works out at £1.08 a Sq metre.
so if you double up the 100mm roll to make it 200mm it only works out at £2.16 a Sq metre.
so not sure on those figures where you got slightly cold from.

Can anyone suggest anyone who does the blown loft insulation under the government scheme?

To find out if eligible for free loft insulation they come and do a survey (well at least British Gas did in July for me). However my old house isn't suitable as the roof construction is not standard so I didn't qualify. This is a great deal though and I have ordered 12 rolls.

Lots of properties are eligible for free loft insulation and EPC. However a hot deal for anyone not eligible.

Really depends where you're insulating, you'll find it anywhere where cold air meets warm humid air, provided you have an air gap that's adequate either on the rafters or the joists you'll be ok, if you're laying it straight on the plaster board that is your ceiling I'd check after a week having had your CH on that there's no significant damp, all comes down to ventilation.

best thing ive done for years was to insulate the loft
as the hoff says CHECK FOR CONDENSATION !! had to have vent tiles fitted condensation was bad.
JohnnyUtah to The_Hoff

Condensation where? On the underside of the felt or underneath the insulation between the insulation and your ceiling?
Might be worth adding not to lay it all the way up to the ends so preventing air circulating from the soffet area.

Don't forget goggles and gloves. This stuff is irritating to say I the least, as is most insulation.

A government run company came and did ours and cavity walls for free. Worth going that route

Double up on the 100mm stuff. Works out at £2.50 per m in total, compared to over £5.00 per m for the 200mm stuff.

looks like if you buy 5 or more you get to pay an extra 6 pound a roll lol

Yep :disappointed: Bit annoying really as it'd be good to stack the up to £30 off £75 to bring it down even more.

200 minimum, get some more down or pay higher heating bills forever.
