Re: Replace Fiberglass Insulation with Foam
A bit if a follow-up.
Spoke to another contractor who uses Demilac products.
Anyone use this or heard of this product?
One plan is to remove the old fiberglass batts, spray about one inch of closed-cell foam for the air barrier, then re-install the batts.
Since the existing batts are kraft faced, would there be an issue with re-installing the old kraft batts on top of the foam? Or should non-kraft batts be used?
If new non-kraft batts are necessary, would blown-in insulation be better on top of the foam?
