Inquiry (采购产品): Urethan rigid board insulation Hello, Recently I put an addition onto my house and the joists are not thick enough to support the required R30 instulation. I have read that the Urethan rigid board insulation can deliver an R30 value at 5 1/2" thick, which would fit in my current joists. Is this something I can get from you, and what is the cost. It would be apprx 168 SF. Thank you very much for your time. **** Hidden Message ***** Jeff Charron 02648 Company: self residential E-mail: jeffrey_charron@intuit.com **** Hidden Message ***** jeffrey_charron@intuit.com
