Cheap insulation at Homebase

[marshman]

Apologies if this has been posted elsewhere but Homebase has cheap rolls of "Earthwool" insulation at the moment.

170mm thick  covers 8 sq metres made by Knauf from old glass bottles apparently!.  Not itchy like fibreglass.  Max 12 rolls per customer and the price.......

Was told online it was £3 per roll but I actually paid £2 per roll!  thermal conductivity is 0.044W/msq

There is the direct link priced at £2.00 per roll, so either marked incorredctly or they flogged you a different length / thickness roll possibly marshman!?

Anyhow, good spot!

There is also a mangers hot water tank deal on again at the moment at B&Q

worth trying to slide another one in round the back of my adhoc foam & fibreglass tanked up tank!

Thanks for the hint. Managed to get 9 in the back of a landy and one in the front by removing the seat.

Glad you found some! Just spent the afternoon "fitting" my 8 rolls (all I could get in my Escort Van) so the side extension now has 2 x 170mm + the original 100mm = 440mm.

So much nicer to work with than the old itchy fibreglass stuff.

I was done! Paid £3/roll at B&Q for what looks like the same stuff but only 5m²  Just spent a couple of horrendous days stuffing it between the joists under the caravan. Couldn't decide how to do it and just unrolled the first one and soon realised this was a mistake so put it in the tin shed. Really needed to saw it in in half first and then unroll it. Every time I need to go in the tin shed I have to get the first roll out and it's just getting bigger and bigger and bigger ... 
I'm sure anyone watching will be getting endless hours of entertainment

Good call. Thx.

Just taken ten rolls out of the small trailer, not too sure about the not itchy bit. Was £2  per roll.

Anyone got a good way of cutting the rolls into narrower slices?

The B& Q version is 200mm which is why the coverage is less. Still better value than Wickes who are trying to sell it at about £35 for 5 rolls.

Woodsaw?

Wear some latex gloves & use a pair of largish scissors, best I've found & keep going back to, bit like a haircut, start at the top, cut it open then cut again into the cut to work a pretty straight line down / through.

Hi
A long kitchen knife works a treat, as well as a wood saw working well.

However it does make for additional handling & action that shakes out a lot of small fibres (potentially) which is why I use the Big scissors option (& i'm a left hander so cack at cutting with scissors). I find it so thorough & simple when cutting & bagging (for instance) that you don't need to hack or exert pressure , having placed it upon the ground / sturdy surface, so if you simply grab the fold to be cut & work inward it flexes enough to see exactly where you have cut, allowing you to follow an accurate controlled line.

saws for this type of work tend to make a bit of a mess once you've tried basic large pair of kitchen scissors it's unlikely you'll use anything else, they're very accomplished.

Thanks. I figured a saw would catch on the fibres and just tear a ragged mess. I think I used a breadknife a few years ago but can't remember how well it worked - it must be up in the loft somewhere......... My mother used to have some big dressmaking scissors if I can only find them. Knowing her they got used for cutting hay bale binding at some time.

I went mad and bought 5 rolls of the 170mm from Homebase as a top-up, chortling at the miserly tenner it cost... only to find it got better:
a) in the flat bit of my 'room in the roof' I only needed 2 rolls to cover, and b) from my hatch at one end it rolled itself out over the entire 7m! Whole job done in 5 mins and for 4 quid!

Thanks for the heads-up here!

Cheers,

It just cuts straight through it. On RockWool. A wood saw would not touch the insulation made from plastic bottles!
