The US building industry speaks loud and clear: There is no better choice than InsulBloc® for insulating exterior walls, masonry cavity walls, and roof decks. InsulBloc is a 2-pound density, spray-in-place, closed-cell foam that forms a fully adhered and seamless insulating, damp-proofing, and air-blocking membrane. InsulBloc offers higher R-values per unit thickness than can be achieved with other types of commercial insulation.
