I have room in upstairs after getting roof replaced I saw that wall open to the roof did not have any insulation at all. So now know why heating it was a
problem just not heat flow that cause problem. Since I have problem handling roll insulation, was thinking of using Super TUFF-Rô Insulation on the studs from inside crawlspace. Should I place foil facing the inside wall or to outside crawlspace / under roof? The two walls to the under roof are only 5' x 18' on each side. The roof makes up the the rest of the room's ceiling.
One other problem is the other room on the that floor is bathroom with drain and water pipes is open to crawlspace too. Thinking off boxing them off and putting insulation too. So they are not open to the cold weather too.
Foil should go to the warm side.
Insulation should go over the pipes. Do not insulate between pipes and heated space. Let heat from house get to pipes to keep them from freezing.
Thanks! I have been lucky, As I had no idea that part was open ..no heat or anything. I plan on building out about 8'' when insulate the box. Make a box out of 2" x 12" x 3' when *marry* it to wall studs. I will use Super TUFF-Rô Insulation on the studs for room and bathrom also from inside crawlspace. Will it be ok to mark where piping and wall plugs are on the board?
