LOFT INSULATION "POCKETS"

[SimonHobson]

idea for the bags - use old wine box inners....

Hmm, modest sized house, insulated to 300mm depth ... lets say 10 to 15 thousand litres. That's going to take some time to empty

I'm not sure about this but how about cordura type thin tarp material sewn as long bags? that should be tough enough & for long lifespan? or would the heat kill that type of material even if it had a reflective top layer of foil type material?

I know a place that may help if the material is deemed suitable.
