Engineering has required that we frame (2x4 bearing walls and doubled 2x12 floor joists sheeted with doubled 3/4 P.T ply) a room underneath a double garage using all pressure treated lumber. We have never used P.T. in this type of application nor in this quantity. This afternoon we set 10 sticks of 2x12 joist material into the hole that is to be the room under the garage and were overwhelmed with the ammonia type odor off gased from just 10 of 60 of these joists and that was in an open hole. What is this stuff going to smell like upon completion? Will this material off gas in perpetuity? Just what are we smelling? Has anybody ever framed with P.T?
Please let me hear your comments ASAP, and yes we live and work in an area where the engineers rule!! Thanks- Worried Sun Valley, Idaho, Builder
