Building insulation refers generally to any material in a building used to stop the transfer of heat cold or sound. While the majority of insulation in buildings is for thermal purposes, the term also applies to acoustic insulation, fire insulation, and impact insulation . Often an insulation material will be chosen for its ability to perform several of these functions at once.

Insulation in buildings will increase the comfort level for the occupants. Insulation reduces heat loss or gain and is a factor in energy conservation in the building. such as: cellulose, glass wool, rock wool, polystyrene, urethane foam, vermiculite, perlite, wood fibre, plant fibre (canabis, flax, cotton, cork, etc.), plant straw, animal fibre (sheep's wool), cement, and earth or soil, but it can also involve a range of designs and techniques to address the main modes of heat transfer - conduction, radiation and convection materials.

2006 saw another increase in the amount of insulation required in new homes in Barrie ON. The new building code now requires a minimum of R-40 in attics and has extended basement wall insulation to within a couple of inches from the floor. Furnaces and air conditioners are also becoming more efficient.

Thermal Imaging has brought about a new method of identifying areas of a home experiencing Thermal Loss. The Building Envelope includes your walls, doors, windows, attic, basement and air infiltration is impossible to see with the human eye. The Barrie Home Inspector www.barrie-home-inspector.com offers Free Thermal Imaging with every inspection.

Did you know that around a third of all the heat lost in an uninsulated home goes through the walls? Heat will always flow from a warm area to a cold one. In winter, the colder it is outside, the faster heat from your home will escape into the surrounding air.

One major cause of heat loss in a home is un-wanted drafts caused by gaps left in doors, windows, attic hatches, wall penetrations and electrical fittings. Proper application of spray foam and caulking can dramatically reduce the heat loss and gain and make your home more energy efficient.
