Hi,
should I dump the old fiberglass and buy again, or just top up with new rolls?
I have a 10 year old house, and looks like the 4 inch fiberglass insulation is the original insulation.
The question is, would you cover this insulation with another layer of new fiberglass, or just dump the lot and start again?
Originally, it was 4 inch, but it's squashed/torn in places.
The other option is to rip it all, place 100mm between boards then top off with 170mm. I guess this would also require getting a skip to dump the old stuff.
Any opinions on which option to go for?
