Insulate Hip Roof By Crawlspace

Place 1 5 in 3 8 cm moisture proof insulation on the exposed parts of your foundation.

Insulate hip roof by crawlspace.

With kraft faced insulation the facing is generally against the subfloor. The sill plate is the first piece of framing lumber and it runs on top of the crawl space wall. This may be done before or after the subfloor has been installed. Cut the insulation to fit the cinder block brick or whatever your foundation is made of.

Make sure they re as tall as your crawl space area and that they re installed tightly against each other use your caulk or foam sealant to seal the seams in between the boards. Cut pieces of insulation just large enough to fit along the rim joist the framing material into which all the floor joists are nailed. For extra insulation repeat the process so that you have a double layer of insulation board. This will limit the moisture that enters your crawlspace through brick or concrete cinderblocks.

With construction adhesive or mechanical fasteners secure your foam insulation boards to the inside of your foundation walls. Then use foundation pins to fasten the insulation to your foundation. When you re using fiberglass batting insulation material run it about 6 inches or so onto the crawl space floor. Use caulk or foam sealant to seal the joint between the top of the crawl space wall and the sill.
