This photo shows TrueSoft Cellulose Insulation blown into an attic to an R-value of 60. The particle board dam holds back the blown in insulation so this home owner can use his attic for clean storage. We use a different kind of insulation underneath the particle board called SilverGlo. SilverGlo is an innovative rigid foam board that is fused with graphite to increase R-value. Just another one of the proprietary products Home Environment Solutions has in their bag!
