I’ve used this on a nice number of occasions, simple to cut and does make a difference. Made from recycled glass bottles apparently.


Its ok as in its cheap but it the worst rockwool i have used will need to use a mask !!


cheers op, the free delivery over £50 swung it for me


This is only a half size roll so shop around before buying you would save some money using encon or Sig.


This is a fibre glass insulation where as celotex is a solid board insulation. Celeotex has a far better 'u value' per m2 but is also a lot more expensive. Normally fit 150mm of celeotex in an average loft compared to around 300mm in fibre glass insulation. Knauf earth wool is generally quite good though,is mainly recycled products and it's is generally less 'itchy' than other products but I would still recommend paper suits and glasses!

Not sure as the PVC may degrade. Perhaps if it is put within tubing and sealed to stop water getting in. Best thing to do is to ask Kenable or even Pro Power who make the cable. There may well be a similar model specifically made for outdoor use in the same way electrical cabling or CAT cabling is within different casings for indoor and outdoor use. Failing all that, Richer Sounds is likely to be helpful.


Would this be suitable for outside?

Poundland used to sell Thinsulate hats and gloves but last time I noticed they had ones with the tag "Thermal". I've been buying Thinsulate products since they appeared in the UK - think I first spotted them in C&A (!) in the mid 1980s.


Love my Thinsulate hat, might get the gloves. If they are as good as the hat, they will be good. Example of how good Thinsulate is - I can't wear my hat long, in slightly warmer times of the year, because my head gets too hot.


£2.47 for the hat now. Nice find bought the Gloves.

Besides putting a carpet and underlay over bare floorboards on the first floor, any possibility of something light under the floorboards for sound and heat insulation? I think I know where my neighbours TV is below me.




I did my loft late last year with this stuff (they had the same offer back then), easy to uses as it is pre cut and wasn't really itchy.


Bought 3 of these, great stuff - only needed 2 though so returned one and got refunded £14.50 - so you can technically get 2 for £29 rather than the usual £32.

Back on - you need to buy 3 or more (any thickness - mix and match) but then the price of each one drops to £14.50. Good value especially on the 200mm.

Blimey, I'm glad I got loads of the Knauf space blanket insulation (covered in mica foil) a few years ago for £5 a roll... those crazy days where energy supplies were subsidising every conceivable green energy saving device, CF lightbulbs for 10p each and such like. This seems like a decent deal though.


Well yeah, thats why I made a general comment, instead of replying to you... :)


probably not for a garden shed :)


Worth remembering... "Some energy providers are lowering the criteria for eligibility as they struggle to meet the targets. This means that most householders are now able to obtain free insulation measures."


sure do you mean behind (say) plywood on battens etc, walls & ceiling? would work well NB also available in the great Homebase sell-off, about £11/ roll

Yeah depends how much you need i guess. Thanks for working that out may help others.


If my calculations are correct, obviously depending on desired quantity: Homebase 200mm rolled = coverage listed as 3.88m2 per roll @ £11.99 = £3.09/m2 Wickes 200mm rolled (3 for 2) = coverage listed as 5.61m2 per roll @ £14.49 (3 for 2) = £2.58/m2 Wickes cheaper by a margin £/m2.

How many American spy drones do we get flying around Britain, and why would they be looking for you ?

No such thing as a standard garage so you'd need the width x the length to get the area, then for building regs you'd need minimum depth of 270mm. If it's a cold roof you'll need to leave 50mm for ventilation. Your joists will not be that big so you'll need to use PIR or fill them with rockwool and then use insulated plaster board.


It's 14.99 at Wickes for the 100mm, minimum is one roll. Not cheaper but if you go on Mondays it's 12.75 any other day 13.39 with discount. But for the bigger thicnkesses this is a good price.


Be careful if external garage might have a problem with damp , see...


Has this item a further discount using the trade card?


Yes, the idea is to fit this in beween the joists from the crawling space and hold tbem with netting.

I didn't say it did.


Doesn't apply to a single person without children.


Doesn't have to be a larger family. The 18k you refer to is actually without children.




Or 42 hours a week on minimum wage. Potentially in a job that is zero hour contract or minimum guarantees hours so that the employer has to make little to no pension contribution. A single parent who works any number of hours in a week to support themselves deserves some help. Anyone who is trying to help themselves should be offered help in heating their home. It's a benefit to them, their families and the environment. At the end of the day anyone who is entitled to benefit and sees this 'deal' is trying to make the little they have go further so surely that deserves some positive reward. They're not at bargain booze or dealers corner spending it on cheap drink and crack. Not all benefit claimers are how they appear to be being portrayed by the mass media.

Half price deal back on again. Just got some instore

Yes, offer finished on Monday.


I was just in store this evening to collect my order from Monday, they had loads of rolls at the entrance but the price was up to £15 when you buy a certain quantity, I think it was 2 or more, so reckon it is £18 for one again now.


Does anyone know if this offer is still on. it's currently showing £18 online just wondering if it's the same instore.


sorry was out fitting it and rewiring etc etc. i think i would have got 6 in my car comfortably without measuring to find out which was best way to put them in. hyundai i30


Right, just ordered 10 rolls. Cheers OP. BTW for anyone else still to order - don't forget to use the 10% off discount code. It didn't work for me to start with - presumably because these are already on offer - but adding a full priced item (a 57p door knob in my case) made the code work and saved me £8.50 off after deducting the door knob cost. Oh and 1.1% TopCashback - every little helps :)

​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.


​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!


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 ...


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.

Not all areas covered (ex. Colchester )... I was called 5 times by different BG customer support in last 6 months and wasted ard 30 mins each (I'm a BG customer but they don't use your details) finally to be told that they don't have any installers in my area and some third party will contact me, which has never happened...


Had two of these surveys done in the three years we have lived in this house. It's a 70's house with built in cavity wall insulation and original loft insulation just reaching the top of the joists. Both surveys claimed we exceeded the minimum amount of loft insulation. More likely there was not enough in it for them already having the cavities filled.


British will do your loft and cavity for free. I think they will even pay for scaffolding if required if they get enough towards their carbon reduction target. You dont have to be a customer either.


Check you may still be able to get it free from Gas/Electric suppliers..and you don't have to be with them
