I am looking for some insulation.
I would like glass fibre/mineral wool. However I don't want it "free" but in a plastic bag or some sort of container. Then you just flatten out the bag and the insulation is in place, and the bag keeps all the fibres sealed in together. Sometimes the bag will have a radiation shield as well.
I have seen this before, especially I think for use in house walls.
But when I search for it on the web, I cannot find any. Does anyone know what this insulation is called ?
TIA.
