What are the Types of Insulation?
Rigid Board Insulation, sometimes called foam board is used in confined spaces where it can be cut to fit. Board Insulation is made of fibreglass, polystyrene or polyurethane and can be used below grade when weatherproofed, or inside the house when covered with drywall. Batts or Blankets are pre-cut to a width to match the distance between wall studs or ceiling and floor joists. It comes either “faced” (paper or foil on one side as a vapour barrier) or “unfaced”. They are usually made of fibreglass. Loose-Fill Insulation is usually blown into attic spaces or exterior walls and is made of fibreglass, rock wool, cellulose or other fibres. Spray Foam insulation comes pressurized and it expands quite dramatically when it is exposed to air. It can be applied commercially or in a small can the size of a can of spray paint. It is ideal for filling gaps and holes that are spots for heat loss. Radiant Barrier Insulation is a reflective membrane that is used to reflect heat away in hot climate,
