Use old duvets for insulation?

I wouldn't be able to rest Tanith. Some lofts have wiring etc and you only need the odd mouse to chew through it. No,I couldn't advise anyone doing such a thing if I couldn't/wouldn't do it myself. It's flammable material.

If in doubt I would cut a small section off and see how it burns.

There was something on r4 yesterday I think, about using old duvets as built in wall insulation in a specially built house used fir research, attached to a university. Also used rolls of wallpaper/newspaper and old carpets.....it was with a view to reducing landfill by using what we already have.

DH has used old carpet in walls and newspaper to insulate pipes when behind plasterboard etc. It seems to work well.

petra probably a small piece would frizzle but a large duvet near joists could do damage.
I'd be paranoid every time I smelled burning.

It would be unlikely to burn if sandwiched between walls and plasterboard. Plastic insulation will burn.

When I had my loft insulation boosted in my previous house, the material was advertised as a cellulose substance. When I examined the shreds that fluttered down, I realised that it was made out of recycled newspapers which is, indeed, a cellulose substance. Good recycling - about 40 years ago - and it was very effective. I hadn't thought of using old duvets as insulation, except as mattress toppers which is a means of insulation too.

I personally would not use an old duvet except in a place that I walked past every day. It sounds the ideal nesting place for mice, or breeding ground for clothes moths!

If you do decide to use it, please, fire-proof it with BURN BLOCK or the equivalent first.

I wouldnt do it - old duvets go to the recycling plant. I strongly believe in using the right materials for the right job - I wonder what view the insurance companies would take off these unusual insulation materials.

A duvet used as insulation could attract vermin. Great nesting material!!

Old duvets will be received with grateful thanks at animal shelters .
