The Triple H Crew installed brand new insulation in this home in Amagansett, NY. The crew first air sealed all the air leaks that were in the attic to make sure the space is air tight. Then they blew in premium Prowool Rockwool insulation to the optimum R-value (R60). ProWool will not burn, get moldy, or attract pest. Blown insulation fills all gaps and odd shaped voids by filling over framing members, "thermal bridging" is avoided.
