Venting a Divided Attic
Hi! New build: single story; slab foundation; 38 x 98 sq ft; 6:12 pitch; 9 ft
walls through out; gable in front as porch; zone 2. Pretty much a long rectangle.
2/3’s of house has 2 HVAC units in attic so it will be insulated as conditioned under the roof with closed cell foam – 4 in. This area is separated with a wall and door in which the wall will also be foamed like the opposing attic wall. Entire space is for the HVAC. Then the next area is right above the garage. This is a 3 car/work bench/storage/man cave/tinkering area (980 sq ft). Framer did not put vented soffits and roofer did not put a ridge vent, in any part of the roof or soffits.
Question is what should we do? We are debating if we should put in soffit vents, baffles, whirly birds or ridge vent on this side (garage) of house only OR use close cell foam on this area too? Interested in best functionality and not esthetics. Also at least one garage door will be opened and closed twice daily. Please advise what would be best for long term and the house!!!
