I'm going to re-insulate my loft. However, the joists are at non-standard spacings (due mainly to additional joists being fitted for a loft conversion), so the pre-cut rolls of fibreglass insulation are no use to me.
It used to be possible to buy uncut rolls of fibreglass insulation, but I can't find them any more.
Can anyone suggest a good source of insulation that I can cut to my chosen width?
I'm going to lay two layers of 100mm thick and will want a considerable quantity as the property is a bungalow.
