I am putting up a 22x26' detached garage and am at the point of installing aluminum soffits and two roof vents.
I live in a region with extreme weather (ranging from -40 to +40 Centigrade) and would like to be able to hold occasional heat in the garage to work outside in the winter.
The package I purchased has open soffits to be covered with louvered aluminum. What is the standard protocol on venting if I want to retain heat? Should these be covered with OSB, or would I have to sheat the entire ceiling for this?
I am looking for an inexpensive way to do this, without loosing the storage in my trusses.
