    |
|
I will be adding onto an existing barn. This will be done in two parts. The first is a 22x11.5' room, all framing will be set on a 5.5x11.5" curb. This will be used to isolate sick cows from the herd. There will also be two 12'x8x27# steel I-beams with trolleys spaced approximately 80" apart to aid in helping up cows if necessary.
Three walls will be exterior and along with the ceiling will need to be insulated to reduce heat loss, (we have looked at both fiberglass and spray foam for this application and are leaning towards spray foam). However, due to the high humidity, and highly acidic barn air involved I will need to use acq treated plywood. I realize all fasteners need to be acq compatible. The fourth wall will be an interior partition/load bearing wall that will not be insulated to permit heat transfer into this room from the rest of the barn. The opposite side of this wall will be an open hall way (with the exception of posts and railing to direct cows) adjoining to the rest of the barn.
I have two questions regarding the construction of this particular room, the first being: Is it possible to sheet both sides of non-treated framing with acq treated plywood without causing moisture problems? Second: would a vapor barrier on one side or the other cause more problems than what it would prevent.
Please excuse the crude drawing, however I hope it helps visualize the layout.
Any suggestions will be greatly appreciated

| The moisture and acid is your biggest enemy. I would highly suggest anything other than wood, even if treated in this addition. Glass board at a minimum on the inside with an exhaust fan attached to a dehumidistat, turning on when humidity gets above a certain level should mitigate the moisture. |
