Unconditioned basement. Insulate walls or trusses ceiling?
New construction (zone 3 southern Utah), with unconditioned walk out basement. Half concrete walls, half framed walls. One door to backyard, no windows.
Super insulated and well air sealed main house. Basement is storage only. All energy efficiency focus has been on the house, being very comfortable and energy efficient. And it will be.
Need to decide real soon if basement walls or basement trussed ceiling gets insulated. My understanding is that code requires one or the other. No one says it can’t be both. Although I like the idea of both, it can get even more expensive.
Now, at 74 and retired, with this being our first home build, I find myself seeking advice and opinions and welcome all responses. Given this a lot of thought and am still not sure what is best approach to take with our basement’s insulation.
