That is one of the jokes in the manual of my John Deere LT155. There are pages and pages of warnings, such as don't put your hand in the rotating blades, don't smoke when pouring gasoline, don't touch the hot engine. don't run over your toes when moving the tractor. The only warning that is not in the manual is the one to keep the muffler box clear of debris. This box is a shield around the actual muffler and is under the tractor between the front wheels. It is a perfect place for grass clipping to collect, BUT unless you make it a point to check it is not obvious when debris is in there. The only safety problem I have every had with the tractor, was when the grass in the box caught fire. I was mowing a long when I smelled grass burn. I checked all around the yard but continued a 100 feet before I notice smoke coming from under the tractor. Fortunately I was able to put it our before any damage was done to the tractor.

OBC 9.25.4.2. (6) provides for a coating applied to gypsum board to function as a vapour barrier, thus eliminating the need for any poly barrier. Your designer should have politely pushed this point with the Code officials. There's no more detailing needed for Membrain than 6 mil. It's not a common product, so the sub is looking for a bigger profit. Try another sub. There's lots of competition in a big city.
