Expanding Foams

Also known as insulation foam, expanding foam is used for stopping draughts, filling gaps, or insulation and dampening sound both inside and outside. Some expanding fillers and foams need moisture to expand and set, so if applying in dry areas, gently mist first. Once set and cured, most spray-expanding foam can be cut, sanded and painted over.
