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 ...you 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!
