Attic ventilation/insulation
Mr9fingerz
| Posted in General Questions on
I have a walk in attic I’m starting to finish and previous owner already replaced the roof and insulated the attic… it has a proper ridge vent but is fully insulated with r11 (faced) and no matter what it’s 100 – 120 Fahrenheit during summer… should the ridge vent be exposed instead of stuffed with r11??? I have no soffit vents either, they are out of the question… thank you in advance

Mr9Fingerz,
Where are you located? That will be helpful as far as offering options for achieving your goals.
Air permeable insulation attached to the roof sheathing can be problematic. Do you know if the previous owner installed rigid insulation on the exterior?
While you're waiting for more input, it probably would be helpful to read https://www.greenbuildingadvisor.com/article/five-cathedral-ceilings-that-work.
I'm in upstate ny (albany area) I have soffit vents in the soffit but I don't think I have the gap between the sheathing and rafters like the diagram shows im supposed to... gonna look when I get home today, I think it's just straight stuffed to the max with the r11 and heat/cold has nowhere to go... up to 120°f during the summer and 50-60°f during winter
So you are in Climate Zone 5a. Ideally, you would have at least R-49 of insulation in the attic.
