Insulation for a Finished Walk-Out Basement
I’m finishing my walk out basement in Zone 4 (Northern Virginia). The house was built in 2003, vinyl siding, house wrap and exterior sheathing. Part of basement is below ground, part above. On interior of the poured concrete foundation, what are pros/cons of the following insulation options:
1. Foamular NGX F-250 (or another rigid insulation), then studs, then drywall
2. Foamular NGX F-250, then studs, ROCKWOOL Safe’n’Sound batt insulation then drywall.
3. Mineral wool directly against concrete, studs, safe n’ sound, then drywall
4. Studs (not touching wall), Safe n’ Sound, then drywall.
Looking for products with least mfg and health impacts, and would like to diminish sound from room to room. Thank you in advance.
