polebarn ceiling insulation

[jaysonb]

i built a 32 x 40 polebarn with roof trusses on 4 foot centers. i put up a white steel ceiling. there is bubble wrap under the steel roof. what would be my best attic insulation ? does fiberglass insulation come in 4 foot roll widths?

You can blow in fiberglass but make sure the trusses are rated for a hanging load,you can end up with a bit of weight and some are not designed to support it.

I will never use insulation again . We have had fibreglass particles on the kitchen table that have found their way past the ceiling lining . I think they will find in the future that fibreglass in the lungs will be as bad as Asbestos .

We have had bush rats living in the Sarking .

Freinds of ours have Rats making homes in the Wool insulation in their house .

I have removed all my insulation and Sarking and will lay perforated battens over the existing Colorbond corrogated Iron and apply another layer of White Colorbond over the first . I will use a vented ridge cap and vent the ends of the sheets . This will cause air to move between the two sheets via convection and remove radiant heat caught between the two . It will also queiten the sound of heavy rain that keeps me awake and also stop condensation forming on the underside of the roof . Landrover used this method on their early 4X4's to keep the interior cool , it was called a "Safari Roof " .

I built a 90 x 48 pole barn that we later converted to a house. We used blown insulation in the attic. It was the cheapest and easiest insulation to install. It took us I and my wife one night to do the whole house.
My attic is vented via perforated soffit panels and the open crest of the roof. There is a "dam" made of fiberglass reinforced plastic hanged over a wire stretched just above the perimeter wall preventing the insulation entering the soffit and plugging the ventilation.
We heat approximately 3600 sqft by a geothermal floor heating. We live in Iowa so it gets quite cold in the winter and our highest (January) heating bill in past four years was less 100 USD.

Mice infestation was problem first year but sealing the perimeter walls around the barn, keeping the grass moved, keeping the garage of free of spilled dog food and poison bait in the attic and sticky traps in the garage took care of it. I check once a while for sign of mice in the garage and in the attic. So far I found the poison bait untuched and the sticky traps free of mice.

Pressure fit/glue 4x8 sheets of any of the many kinds of foam board available between the joists? You can get the white poly foam in 5" thick pieces.

I'm with redneck in training. Put your soffit baffles in and blow in fiberglass. I used 2" Styrofoam to seal the space below from the attic. I cut it to fit and nailed & silicone'd them beneath the beams, between the posts. You'll want to do everything you can to seal any penetration into the attic area.

my building gets alot of wind, is there any chance that wind thru the soffit could blow the fiberglass toward the opposite side of the attic ?

I really doubt wind will be your issue. What about critters taking the insulation
