Spraying in Closed-Cell Insulation

Bob is joined by Jim Remick of Nickerson -Remick insulation contractors. Remick tells Bob that this NCFI-Honeywell insulation technology is more and more in demand from builders and contractors. When the liquid insulation hits the wall, the two chemicals react causing it to expand. This closed-cell foam is a moisture, vapor, and air barrier that sets up in a matter of seconds. It will be 95 percent cured in 4 hours, and 100 percent cure in just 24 hours. Once cured, it will give an R Value of 21, which is exceptional. It can only be applied in open cavities because it expands away from the exterior wall and would completely blow off existing wall treatments. There is no need for an added moisture barrier with this closed-cell insultaion. It will provide twice the insulation value, or R factor, but cost three to four times as much to install as average insulation. But the heat savings should be 30 to 50 percent over any other insulation product, bringing rapid payback for intitial installation costs. More information
