High Density Closed Cell Spray Foam
Spray foam can be used as an insulating and air sealing product.

Spray foam is very versitile and can be used in almost every insulation application. Applied at 2" or more spray foam also acts as an air seal and a vapor barrier.
The insulation is sprayed, via special equipment, into wall cavities and expands to fill all the nooks and crannies in a wall cavity. When necessary excess foam is scraped off the framing to form a uniform wall cavity. Spray foam insulation makes it easy to completely fill wall cavities with insulation and to perform air sealing in the same step.
By acting as a wind and air barrier, it often eliminates the need for separate air-tightness detailing which can increase energy efficiency and allow downsizing of the heating and cooling system equipment. Sprayed foam insulation does not shrink, sag, settle, or biodegrade.
The advantages of closed-cell foam compared to open-cell foam include its strength, higher R-value, and its greater resistance to the leakage of air or water vapor.
