1405.0. "Moisture build-up" by MTADMS::DOUGLAS () Wed Dec 26 1990 07:29

    I have searched through the barn keyword and have not found anything
    regarding moisture build-up in a barn.
    
    The woman I bought the barn from mentioned that a door must be open at
    all times in the winter to prevent moisture build-up and so the barn
    can "breath". There are vents along the whole length of the eves of
    the roof.
    
    I have been closing the doors on the very cold (-10 degrees etc..)
    nights and have noticed moisture dripping from the rafters in
    the morning when the sun comes out.
    
    The wood still looks good, however. It is a wooden framed barn with a
    metal roof. Should I be concerned about this? Is there a better way
    to let the barn "breath" other than keeping a door open which creates
    a draft?
    
    Suggestions appreciated!

1405.1Ventilation is criticalMSBCS::A_HARRISWed Dec 26 1990 10:3023
    I'd be more worried about the horses than the condition of the wood
    (although you certainly don't want to rot the timbers.) Everything I've
    ever heard says that a moist barn is unhealthy and leads to respitory
    problems. A cold barn is a healthy barn. If you see dripping then that
    is really moist. Is the open door really creating that much of a draft?
    Especially if it's open to an alleyway that runs between stalls it
    won't be blowing right at the horses. 
    
    My horse developed heaves after living in a closed-up barn with very
    little turn-out for a couple of years. Now that I've built a barn, he's
    free to go in and out 24 hours a day. I'll only close his stall door if
    there is driving rain or snow that would get the stall wet. This is the
    vet's recommendation.
    
    If leaving your doors open isn't an option, you may need a carpenter to
    help you find where to add more vents. It doesn't seem to me that the
    barn was designed right--you shouldn't HAVE to open the doors to get it
    ventilated. That should have been one of the first things added to the
    design.
    
    Be careful--respitory problems are no fun for you or your horse.

1405.2Call a builder for adviceCSCMA::SMITHWed Dec 26 1990 11:0813
    It sounds like you have moisture getting in the barn somehow. You
    probably have dirt floors and if the barn is fairly old your foundation
    may not be deep enough. This allows moisture to travel under the wall
    into the barn.  You may be able to stop this by putting drainage
    around the foundation (a trench with stone and pipe).
    Don't doubt the seriousness of the water on the beams. This can
    cause serious damage in a very short time. I've seen it wear in
    just 2 years time the beams were so dry rotted that you could punch
    a hole through them with a hammer. 
    call a builder in your area, they may be able to give you some
    professional advice.

1405.3moisture build upWJOUSM::GARROWFri Jan 04 1991 08:437
    I just had a carpenter in my attic to see if I had moisture build up
    because I was getting water stains on my cielings.  Luckily I didn't
    but if I did his suggestions was to make larger vents in the upper part
    of the house.  Thye usually only have small vents.  Maybe you need
    vents so the moisture can escape..  It's worth a try !!

1405.4Does the roof have a vapor barrier?DECWET::JDADDAMIOAdmire spirit in horses & women!Fri Nov 15 1991 16:4022
    I just re-read this note because we're planning a new barn. I don't
    know how I missed the METAL roof the first time! This sounds like 
    condensation caused by the barn air hitting the cold metal roof.
    I'm assuming that your roof is installed the typical way: boards on top
    of the rafters which run at right angles to the rafters; spaces between
    the boards; and the metal roofing nailed on top of the boards.
    
    The normal amount of circulation in a closed up horse barn is
    inadequate to prevent condensation on a metal roof. In an open structure 
    like a 3-sided run-in shed, there is no problem. But, close it up and 
    condensation appears like magic. Just the horses' breathing introduces
    enough moisture into the air to cause condensation if it comes into
    direct contact with cold metal.
    
    That's why vapor barriers and/or insulation have become standard in
    metal livestock buildings which will be closed up. Especially true
    here in WA where the winter air has a moisture content near 100% BEFORE
    you add in the horse's breath!
    
    So, you really have 2 choices: Find some way to increase the air
    circulation or install a vapor barrier to prevent the barn air from
    contacting the metal roof.
