Get three rolls of DIY loft insulation for £3 at B&Q this weekend only, from Fri 27 - Mon 30 Aug.

The insulation is glass wool and approximately 200mm thick. B&Q says it has over 20,000 rolls available at this price. Not only is loft insulation good for the environment but it can cut your energy bills by about £150/year too.

The offer's in store only in the majority of B&Q branches nationwide.

How many rolls do you need?

B&Q has a nifty online calculator which will tell you how many rolls you need based on the square foot area of your loft.

According to the Energy Saving Trust 270mm is the recommended depth for wool insulation to get the maximum amount of heat insulation, though other materials differ. More info at the Energy Savings Trust.

Free loft insulation?

Anyone aged over 70, plus others in receipt of certain benefits, can get grants to help pay loft insulation costs, or even get it for free. Full details in the Energy Grants Guide.

#8
Good stuff. House is much warmer now. Had 170mm to start with and topped it up with 200mm insulation.
Paid £5 a roll last year.

No.
#10
Also guys, dont forget not to lay this right up to the eaves - you need to allow some gap for ventilation.

Of coarse you can. As long as you are not planing to walk on it or stack stuff ontop.
#13
Could i use this stuff to insulate my garden shed as last winter most of the food and drink i keep in the shed was frozen.
#14
well worth doing, did mine last winter to 270mm, made a massive difference.
you can lay on top of boards, like markvirgo says, just can't walk on the boards afterwards

well worth it - hot

Exactly, course you can lay on top of the boards. Infact the board will act as insulation first! You wouldn't then walk on the insulation or use as storage.

Best thing to do is lay 100mm then cross layer with 170mm - this gives you the recommeded 270mm. If you want to use an area as storage then lay with 100mm then either board with poly type and board or double layer the spaceblanket board and or place board on top.
#21
OK my apologies, was being a tad thick.

What I should have said is that you shouldnt put it UNDER boards.

In any event, putting it on top of boards seems silly, as it prevents the use of the boards - guess its horses for courses though.
#22
I'm about to have this done for me. I currently have a very thin layer of insulation, about 80mm. I am having new joists laid at 90 degree angles to the current ones over the top, adding 200mm in height. This will then be filled with insulation and boarded over, meaning I'll have the right level of insulation but still have a floor usable for storage. Not that I plan on going up there too much, but I do need it as storage space.
#23
If it were me, i would insulate with 100mm between the ceiling joists and then use these rolls over the top, rolled out in the opposite direction to make up the 270mm thickness. Anywhere that was boarded out i would insulate underneath and leave it at 100mm, or box out the boarding so it was effectively 170mm higher than it was previously so you can still get the full 270mm underneath.

Perfect way to sort it, probably a bit too much work for a lot of people, especially if the roof space is already boarded out.

Your limited to 100m2 coverage. Trade/Tradepoint customers are not allowed to buy.
#27
is there any harm in going over 270 mm ? I think I have 170 already .... novice question probably
#28
Great price but with only 20,000 rolls available nationwide I can see most stores selling out in about 5 minutes

No the more the better really. The regulations only require you to add more and more as they improve energy savings standards. I work in an architects practice and we now specify 350mm insulation to get the required 'U' Value

When this deal was last on, I managed to get 45 packs for my new build house. I kept the pacaging in case it came up again as I still need another few packs! The size of the packs last time was as follows:
Length 4900mm
Width 3 x 370mm
Area 5.4 metre squared per pack
Thickness: 200mm
So: Each individual roll covers 1.813 metre squared and each pack of three rolls covers 5.4metre squared
It's good stuff - made by Knauf and last time there was a limit of 15 packs per customer. You'll need a big van though as three of us went last time in three vans to pick it up for me!
Hope this helps!

That helps a lot. Thanks :-)

So at £3 for 5.4 square meters it looks like I will be able to do my loft for £21. Great.

Managed to pick up a few in Reading. I had to make 2 trips! I think they were running out quickly.
#38
Cheers OP got a load from Rochdale, only got 6x3 as thats all I could get in the Xtrail. 8)
#39
This has saved me hundreds of pounds. Best deal ever. Previous best price for this (locally) was £15 per roll. I managed to buy 24 rolls today, saving nearly £280.

I'm gonna be itching for weeks though. :(

Thanks for the heads up. :)

You sound a bit confused. Why shouldn't you put insulation under boards?
