Insulate hip roof by crawlspace.
Install an air and vapor barrier over the floor and tape it to the insulation.
Cut pieces of insulation just large enough to fit along the rim joist the framing material into which all the floor joists are nailed.
This may be done before or after the subfloor has been installed.
The sill plate is the first piece of framing lumber and it runs on top of the crawl space wall.
Place 1 5 in 3 8 cm moisture proof insulation on the exposed parts of your foundation.
The best way to insulate a crawlspace would be to do it from the ground up and consider it just part of the conditioned space as you would with any basement.
Use caulk or foam sealant to seal the joint between the top of the crawl space wall and the sill.
When you re using fiberglass batting insulation material run it about 6 inches or so onto the crawl space floor.
With kraft faced insulation the facing is generally against the subfloor.
With construction adhesive or mechanical fasteners secure your foam insulation boards to the inside of your foundation walls.
In a vented crawl space the underfloor should be insulated similar to how it is in ceilings.
Cut the insulation to fit the cinder block brick or whatever your foundation is made of.
Then use foundation pins to fasten the insulation to your foundation.
