Johns Manville Spider fiberglass insulation – San Francisco Area – storage attic insulation
I’m looking for an insulation for a storage attic in California Zone 3a (Marine influence). It’s a metal roof, with 2×6 rough sawn rafters at 6:12 pitch.
Spray foam (SPF) is certainly an option. But it’s fairly heavy, has to be installed well to avoid toxic problems, and it burns.
What about Spider for this? I’ve read about it, but been unable find any installers or any local examples. Is it still viable?
