So I added an air conditioner to my shop not too long ago and would like to step up the insulation in the walls and ceilings. Currently I have 40+ year old fiberglass that is in rough shape. Would love to have spray foam but it’s just not in my budget. With that said, where is the best place to get 48” or even 60” wide fiberglass bats? Manatee has something like 65ft for $270 or so which seems high to me with it being only 65ft of it. I live in the hot and humid south. I have searched online and not many places advertise their prices on their websites. I really don’t want to have to send out a dozen emails for pricing. With that said, do you guys have a suggestion or two on the best places to check with and what should I expect to pay for 3” thick x 48” wide x 100ft long rolls? What about 6” thick rolls?
