insulating crawl space
 
Hey Guys,

new to the forum - I have a couple of questions regarding insulating our century old church turned house.

The main idea is to keep the crawl space Vented. The house is built on a large slab of rock and instead of insulating the walls to the outside - of course - I was planning on insulating the floor underneath the house in order to keep the heat in and allow the crawl space to vent to the outside.

I am currently adding some in floor tubing to the floor and was planning on creating a sort of 'heating cell' with a rigid thin foam of a corrugated type that woudl allow me to maintain some air space between the foam and the underneath of teh floor wood slabs. and I would then spray foam the underside of this now created 'heat cell'....

I was intending on using something like this:

So - am I heading in the right direction??

Spray foam the band joists (cc SPF is preferred) and cover the joist with rigid foam after you fill the cavity with insulation.

so apply vapor barrier directly to the wood slats underneath the flooring?

It would have to be sone in sections between the large timbers as the house was built on large tree timbers. that are spaced across the length and width of house main flooring.

There is no ducting that runs underneath in the crawl space only a few electrical wiring and of course the septic line.
