Will using air-sealing tape on the OBS sheathing joints make my new house walls unable to breathe?
I am building a new home in Eastern Canada. The exterior walls have OBS sheathing on them and will be covered in house wrap and then 1.5 in. Ener air breathable foam. On the inside for insulation I am putting R20 batt insulation with a Vapor barrier. Should I tape the seams on the OBS sheathing or will this make the walls to tight and not able to breath properly?
