Trust Capitol Building Supply for All Your Insulation Solutions

We 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.
• Loose-fill and blown-in insulation – made from cellulose, fiberglass, or mineral wool. Loose-fill insulation is most useful for hard-to-reach places, enclosed existing walls, open wall cavities and unfinished attic floors.
• 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.
