Vented and unvented attic space
We are currently considering foam insulation during the framing phase.
Basically the trusses span over our patio area, approximately 15′ with glulam at bird’s mouth.
When looking at foam they will create a ‘rake wall’ with foam to enclose the attic from top plate to roof decking.
Do we need some sort of venting in this section of the attic (outdoor patio)? It will be an unconditioned space.
