Polyisocyanurate and placement for baffle
Hello all, I am finally getting around to adding my insulation and all on the interior of my brick walls(was held up repairing trusses). The plan is to make my own baffles going about 6 to 8 feet up with ridge vent. I am in zone 2 with r11 batt attic insulation with blown in on top of that. Question is, do I run the foam straight up from the wall right into the baffle…or go up and over my top seal(concrete header beam) to the edge of the house, and then up with the baffle. I am designing it with typical soffits at 12 inch overhang(short for extra hurricane protection) Going up and over seems better insulated but I dont know if it will hinder evaporation near the truss heels. They are sitting directly on concrete…no paper or anything.
