Masonry Cavity Fill FOAMED-IN-PLACE completely fills the cavity between double walls, fascia walls, utility brick wall systems or cosmetic walls systems, producing excellent sealing around conduit, fixtures, pipe chases and fittings while still allowing the wall to weep as constructed. Core-Fill can provide R-Values comparable to or higher than rigid board insulation, without the potential problems of toxicity and flammability, or the well known difficulties of fitting board seams around obstructions in the wall system (such as masonry ties, pipe chases, windows, etc.) or the failure to properly tape or apply the manufacturers specified adhesives to the rigid board. |
