Trust Us for All Your Insulation Solutions

Westmont Interior and Contractors Acoustical carry a full line of insulation products for both interior and exterior applications – from commercial buildings and unfinished floors to residential walls, interior/exterior walls, and enclosed spaces. Our fiberglass, cellulose, and mineral wool insulation solutions include: 

  • Batt/roll insulation – made from fiberglass, mineral wool, plastic fibers, or natural fibers. Batt/roll insulation is used on unfinished walls, foundation walls, floors, and ceilings.
  • Rigid foam board insulation – made from polystyrene, polyisocyanurate, and polyurethane. Rigid foam board insulation must be covered with ½ inch of other materials (like gypsum board) or with weatherproof facing.
  • Unfaced insulation – features no moisture barrier and is often used in remodeling, walls, floors, ceilings, basements, attics, and crawlspaces.
  • Rigid fiber insulation – made from fiberglass or mineral wool. Rigid fiber is often used in locations that are subject to high temperatures, such as ducts.
  • Mineral wool insulation – this special type of batt insulation is made from inorganic materials and is naturally fire retardant. It also reduces unwanted noise transfer between rooms, does not deteriorate, can be installed at any temperature, and is resistant to water, mold, and mildew.
