Cutting Insulation

[Munroast]

Just seems to be one uncut roll, what is the best way to cut it? typical hand held cross cut wood saw whilst it is still rolled ?

and also, have the chance of some yellow (fibreglass stuff) that was used in an 1985 comercial property - its going for land fill, didn't know whether to bring some home and add to the 11 inches already in the loft

I use an old bread knife.

The yellow fibreglass sheds irritant dust and fibres. I have a chest complaint and it affects me severely so I will not have it in the house and clear it away using mask, goggles, hat and a canister vac.

The more modern mineral wool treated with Ecose (it is light brown) marked on the packaging does not shed.

Another vote for bread knife.

Yeah, normal wood saw while it's still rolled up, or you can get dedicated insulation saws that look like a wood saw with no teeth. Modern rolls of insulation are often pre-perforated at 400 and 600'ce très and can be cut to those widths just by plunging your fingers into them and ripping them apart, still rolled up

I'd say yes to save the insulation from landfill and add it to your loft, but maybe roll it up outside and cling film/brick wrap it to bring it into the house otherwise it'll shed loads of fibers everywhere
