RetroFoam is a nonflammable, insulation and air barrier material that can be injected into enclosed wall cavities. This effectively seals the cavity against air movement, creating optimal insulation.
RetroFoam is ideal for enhancing old or insufficient insulation in existing properties. This is because, unlike conventional insulation (fiberglass, cellulose, etc.), RetroFoam doesn’t settle, lose its shape, sag or compress. The job of insulation is to keep the indoor temperature consistent without the need of a furnace or AC constantly running.
