Hi,I have a 40x50x12 metal building and I am thinking about insulating the ceiling with spray
foam insulation the following are questions that I would like opinions on.
(1) how thick do I need to put it on.
(2) how much it might cost at the thickness I will need to get decent (r) value
(3) I live near olympia,Washington so it doe,s not get too cold like 10 to 15 degrees
(4) can I just put bat insulation on the walls to help keep the cost down which can do myself
thank,s
I was told that if I put bat insulation up on ceiling I would have problems with condensation on bats,but I was thinking that if I put up thin paneling I could then put bats on top of them and leave some or all of the ends
open for air flow to keep keep condensation to minumin and this will keep the cost down,thank,s
