Updated February 21, 2017

Insulating your home is a low-cost way of improving your home's energy efficiency. In addition to saving money, you will also help to keep the temperature in your house at a comfortable level. Many types of insulation methods are available. Knowing about the different types will help you to make the best choice when considering insulation for your home.

The batt and roll method of insulation is common and affordable. Batt and roll insulation can be made from fibreglass, which is made of flexible fibres. They can also be made from plastic fibres, cotton or wool. The continuous rolls can be hand-cut and trimmed for a snug fit. Some manufacturers include facings such as vinyl. The facing acts as a vapour barrier or air barrier. This insulation method is normally used in floors, attic, sidewalls, basement and crawl spaces. It does not require professional installation, but homeowners must take precautions when handling fibreglass. You may also choose to use as certified installer. This type of insulation is among the cheapest.

Rigid Insulation

The insulation product is made by pressing and moulding millions of densely packed air cells into a board-like form. Installation usually requires an HVAC contractor, which can increase the cost. However, it may be possible obtain a higher R-value with rigid insulation than with roll and batt.

Spray-Applied Insulation

Spray-applied insulation is typically used in places that are difficult to reach. This method offers a tight fit around electrical sockets, pipes and sidewalls. It can be used throughout most homes, sealing up the spaces between wall studs. Large spray insulation jobs typically must be done by a professional, which increases the cost of this option.

Reflective Insulation

Reflective insulation is made from aluminium foil. The material that makes the backing is usually made from cardboard, plastic film, Kraft paper and polythene bubbles. This type of insulation can be installed in ceilings, crawl spaces, basements, floor joists and wall studs. It is normally used in the warmer climates to reflect heat away from living spaces. It is best to have a certified insulation installer to do this type of insulation, which adds to its cost.

Foam board Insulation

Foam board insulation can be used in most parts of the house. This method of house insulation can add structural strength to your house, as well as thermal resistance. This type of insulation is properly installed by a certified insulation installer. Costs vary, but professional installation is usually required.
