We apply polycell sealant on all top plate and bottom plate penetrations as well as all floor and ceiling penetrations. This seals all gaps and air holes that if left unsealed, create drafts and inefficient homes. Spray-applied cellulose insulation is used on all walls (R-20), all attics (R-38) and in all mid-floor truss systems (R-20). Cellulose cavity insulation is also used on all interior bathroom walls, utility room walls, media room walls and master bedroom walls for noise suppression. Combined, these insulation technologies result in the most energy efficient and acoustically isolated homes available.
