At our new place in Saskatchewan we have an unfinished round top quonset that has 4.5" laminate trusses. It's not insulated and has 10'x12' sliding doors front and back. The back portion has 2 nice box stalls, so I will remain as the 'horse area', but I'd like to finish the front 1/2. There is a nice concrete slab in the front 1/2, and plank flooring in the horse section.
I'm wondering what you all think about insulating, vapor barrier-ing, and sheeting the interior of the front half, and building an insulated dividing wall between the front and back. I'm also thinking of putting a nice (and nice sealing) 10'x12' overhead door on the front, and putting in radiant heat.
Is 4.5" of insulation enough, or am I trying to seal up a building that was not ever meant to be used as a nice, sealed, space??
Appreciate your thoughts,
