Recognize this insulation?
There are 2 types I’ve found. Is the one covering the attic floor look like blow in cellulose? or vermiculite? And the one that’s like a sandwhich between the roof rafters some kind of old house wrap? That one is wrapped in a kind of tar paper …
Neither are sparkly or shiney, though perhaps that is due to all the dust. It is very fluffy.
Crawling through our knee wall attics in a Cape Cod built sometime between 20’s & 40’s, I bumped into these and wonder if a previous owner did a deeper weatherization or efficiency program that a home auditor had assumed… I’ve also found typical “pink” fiberglass batts and Tyvek but this stuff looks much older. Also found no signs of air sealing (no caulk/sealant, batts that are darker colored, etc.) though there is black tar paper over the board sheathing on exterior walls.
