we passed our framing, electrical and plumbing inspections!
so now we need the northface jacket. most of you are probably saying, huh? what the heck do you mean? well, think about it this way…
on a windy day, you want to wear a windbreaker, right? and a cold day you want to wear a sweater. on a cold windy day, you want to wear both. well, your house needs the same thing.
the envelope – the very outside layer of the house – needs to be sealed up. any cracks between the sheathing, the floor boards, anything like that, are like holes poked in the windbreaker.
after everything is sealed up, ya gotta install insulation – a warm sweater for the house. in all walls, floors and ceilings between unconditioned and conditioned space, like the house and the attic. a lot of houses use batt insulation.
but we’re special. so very special. so we went with spray foam. it’s a combo of sealing and insulating. it’s more expensive, but it works really well in our situation and with how many cracks, gaps and seams there are in the framing and sheathing.
and what about the interior walls? well, the only time you need insulation for interior walls is when you want it to help dampen sound. otherwise, interior insulation is not necessary.
