Big-Foot Posted November 2, 2012 Report Share Posted November 2, 2012 Hi guys, long time reader and have searched but could find nothing on this. I am about to put my home on the market and a friend of mine mentioned I might have a problem area to address. The garage is a large 2.5 car unit with an addition off on one side. The walls are thoroughly insulated with fiberglass, but the walls were covered with plywood rather than sheet rock. He said that the fact that it is heated will require sheet rock on the walls. I have had a 100k BTU gas furnace in there in a corner for years and no issues and liked the fact that the walls could take a beating without damage. Plus, it was easy to hang cabinets etc as the plywood is 1/2" thick. What say you guys and gals - do I need to cover the plywood with sheet rock in order to meet any requirements? Other options? The house is in Minneapolis if that matters Link to comment Share on other sites More sharing options...
Big-Foot Posted November 2, 2012 Author Report Share Posted November 2, 2012 This forum software and our ipad do not get along. Tried to edit and add that the house is in Minneapolis MN and also that the ceilings are done in plywood as well. Thanks for any pointers! Link to comment Share on other sites More sharing options...
kurt Posted November 2, 2012 Report Share Posted November 2, 2012 You should have a drywall fire separation between the house and the garage. Link to comment Share on other sites More sharing options...
Marc Posted November 2, 2012 Report Share Posted November 2, 2012 R315.1Wall and ceiling.Wall and ceiling finishes shall have a flame-spread classification of not greater than 200. Check out the flame spread index of soft plywood on the last page of this document: AWC Flame Spread performance of Wood Products. They're all within the acceptable limit set forth in R315.1 Marc Link to comment Share on other sites More sharing options...
Big-Foot Posted November 2, 2012 Author Report Share Posted November 2, 2012 Thans for the replies guys.. Kurt - The Garage is detached and a good 30' from the huse. Does that count? Marc - Good reading you and your link. I have bookmarked it for future reference! Thanks.. Link to comment Share on other sites More sharing options...
kurt Posted November 2, 2012 Report Share Posted November 2, 2012 Yeah, that counts. Forget the drywall. Link to comment Share on other sites More sharing options...
John Kogel Posted November 2, 2012 Report Share Posted November 2, 2012 You are selling your home as is. If someone gripes about the garage, offer to have it jacked up and removed from the property. [] Link to comment Share on other sites More sharing options...
Garet Posted November 2, 2012 Report Share Posted November 2, 2012 I've never heard of heat vs no-heat affecting what surface finish is acceptable. Ask your friend where they got their information. Link to comment Share on other sites More sharing options...
