In Ontario building code, "membrane" and "sheathing" are used thousands of times. When we are saying membrane in every day life, it means a thin sheet, like paper or wrapping sheet, while in OBC, a sheet of "gypsum board" can be called "gypsum board membrane", see OBC SB-2 2.3.4.(1).
My questions:
1. how does building code, use OBC for example, define the meaning of "membrane"?
2. sheathing is another word having similar meaning to "membrane", how does building code, again for example in OBC, define the use of "sheathing"?
