3 so any type of insulation you choose will likely require air sealing.
Type 1 spray foam insulation.
The foam has an r value resistance to heat flow of 6 meaning it can trap gases denser than air.

Fiberglass mineral wool spray foam and loose fill cellulose all require air sealing to work properly.
Spray foam insulation or spray polyurethane foam spf is an alternative to traditional building insulation such as fiberglass.
However foam insulation has higher r values and forms an air barrier which can eliminate some of the other costs and tasks associated with weatherizing a home such as caulking applying housewrap and vapor barrier and taping joints.
A two component mixture composed of isocyanate and polyol resin comes together at the tip of a gun and forms an expanding foam that is sprayed onto roof tiles concrete slabs into wall cavities or through holes drilled in into a cavity of a finished wall.
Polyurethane foam including foam rubber is sometimes made using small amounts of blowing agents to give less dense foam better cushioning energy absorption or thermal insulation.
