Carpet over Insulation in attic.

Boooourns

Does this work as an idea? I live in a bungalow and I have insulation laid on the attic floor from years ago and now i have a lot of old carpet now laid on top of it, will this help retain heat in the rooms below?

Between the rafters or over them? If people can't see the rafters they will eventually put a foot through.
Thermally it would probably work better upside down, catching slow moving air in the pile.
I'd forget it and buy more rolls of insulation if the old stuff has gone flat.

I have it over the rafters. If i was to buy new insulation, can i roll it out horizontal across the old vertical insulation to improve it?

If there is any gap between the carpet and the insulation underneath, then adding new insulation on top of the carpet will be of little benefit, if any. Lose the carpet, then do it.

Ah I meant this, I'll remove the carpet and lay more insulation.

Carpet will reduce the airflow through the insulation. Glassfibre / rockwool ?

So if you have a very draughty attic, the carpet will probably be just as good as another layer of glass.
