How much space does this cover?

Also, forgive my thickness here, but is it only suitable for laying flat? I have a wooden shed I wanted to insulate, but down the walls. Would this work, or should I use polystyrene boards?

It appears to be 8m2. With regards to the shed, I'd just be aware that it's 17cm thick, so it would probably be a bit too deep to run down your walls - the 10cm stuff would be better if was available. It would compress down though, so might be worth trying to put it behind some ply cladding on the shed wall for instance - for a fiver you can't go too far wrong!

Pack says 7mtr x1.11mtr 170mm thick compressed for transport.

If using to insulate a wooden shed & its really too thick for that, compressing it looses its insulation value, remember you need a membrane to stop sweating.

Is this a nationwide offer? Do you have a product code?

I spoke to a few local homebase stores regarding insulation products and I was informed they had no plans to bring out promotions like this again...

Go to the page on the web: homebase.co.uk/web…014
and check availability at local store. 7 out of my 9 nearest stores (S & W Yorks) had plenty of stock, on average about 100 rolls each, so I'd imagine it would be nationwide with just the odd store out of stock. A few stores have a facility to reserve as well.

Would this be ok to put in the loft and board on top of?

The stuff i have now comes over the top of the joists so wil have to squash it down to put the boards on, obviously making it less efficient

Just picked up 11 rolls from homebase Swansea......couldnt get any more in the car:roll:

Cheers all. Not sure I can do the ceiling, but will be trying. Not moved in yet, so not sure!

Does the above comment just relate to insulating the walls of a shed or does it apply to normal usage in a loft space (in a dwelling)?? I've checked the manufacturers site and there is no mention of needing a membrane.

this dosnt have a very good insulation rating compared to other options, if i remember right.

its mickey mouse

Not sure if I would trust plastic insulation, in case I leave the chip pan on next time I'm comatosed of a Saturday evening...

Only if your boards are mounted high enough not to compress the insulation. Compress it and it doesn't insulate as well. I fixed some 'stilts' to my joists and boarded ontop of these with the insulation underneath.

That is only for the smaller rolls - these rolls are supposed to be limited to a 100 square metres per customer because they are being subsidised by Eon

Earthwool CarbonZero is a high perfomance glasswool made with recycled bottles with higher thermal performance compared to other loft insulation. (its not made from plastic bottles)
The reason its diy only is because its a subsidised product by E.ON under the Carbon Emissions Reduction Target and its not supposed to be for builders to buy cut price and fit making a hefty profit.

This will work on your shed walls, as long as you sandwich it in place (try not to compress it too much) and it should be more efficient than polystyrene sheeting. However, much better still is a product called Celotex, which is a foil backed foam sheet, more effective than these rolls and easy to fit to ceilings/walls.

You are correct. I have just received an email to that effect. Let us know how you get on - good luck :thumbsup:

I too have a boarded loft. There is a 50mm piece of insulation already under the boards (that's all that the joists will allow) and this is not sufficient to insulated my old Victorian house.

What I am wondering is would it be of any benefit rolling this on top of the boards (I don't use the loft for anything)? Or has the heat already been lost once it has gone through the boards?:oops:

Insulating lofts is 250-300mm thickness quilt no more otherwise condensation can build up in the quilt and decerease its ability to perform when laid butt each one tight to the other to seal all gaps and the next layer is to be laid 90 degrees to the other one below. It should be laid between joists and then over the joists with the next layer. The 170mm roll is designed to be used with 100mm thick to give overall 270mm as within the spec above. If the insulation is compressed in anyway it will not perform. If you want to put a floor in your attic be aware to obtain 250-300 thickness with a floor on top this will have to be spaced up from the existing timber joists and using timber to do this could over load the existing timber joists (Boxed hollow plastic sections is one method to acheive this) . Finally best insulate your shed with 2" thick polystyrene easy to cut and will squeeze fit between the timber frame inside and you may need to put air vents in to remove condensation PS you might need to put a double glazed window in now (Joking)
hope this helps :whistling:

You can roll this over your boards fine. The only downside (like in my loft) is that once you've done it there is no way of knowing where the joists are!

Just picked up 4 in Swansea - it's not on display yet so you have to ask.

The ones on display are 19.99 BOGOF.

now showing as a tenner a roll online

celotex is the daddy,kingspan is dearer (same product) but i prefer celotex as its heavier and feels better imo... its very expensive tho a whole house would cost u 1000's to do right

Great deal this - went into store and picked up 6 packs - 5 quid each and BOGOF. Had to ask for them though as they were in the back of the store.

To recap 6 packs for only 15 quid.

Nice one Mike heat and repped :thumbsup:

I sent an email to Homebase customer services asking if the insulation should have been BOGOF and got this response:

Thank you for your e-mail regarding loft insulation.I am sorry but the … Thank you for your e-mail regarding loft insulation.I am sorry but the buy one get one free offer only applies to Space Blanket loft insulation not Carbon Zero loft insulation. If you would like these instead I would recommend to return the unopened items, along with your proof of purchase, back to store. I am sorry for any inconvenience caused.



Still, I'm not complaining because I'm happy with the price for the amount you get in a roll.

I suspect that the reason it is for DIY use only and that Homebase impose a limit on how much you buy is that it is subsidised by E.-on. It could still be mickey mouse stuff, but I suspect that its a good deal.
