John Sayers' Recording Studio Design Forum Archive

I see a lot of brand names thrown around here, but not a lot of specific product numbers for other brands. Are the following all the same thing (for our purposes)?

Owens Corning 703

Roxul 40 or AFB

Johns Manville IS 300

Certainteed OEM 300

What other brands (with product numbers) should I be asking about?

YEs they are.

Ask for 3.lb/ft^3 fiberglass or 4lb/ft^3 mineral wool. Don't mention make, hear what they offer. Bob Gold's page is LOADED with this information.
