Insulation

Insulation is a material that resists or blocks the flow of heat energy. Insulation is used to stop heat inside the home from escaping in winter, and to stop heat outside the home from entering in summer.

​

The best type and location of insulation will depend on your local climate, and whether the insulation is mainly needed to keep heat out or in (or both). The first step towards getting a good result from your insulation is to understand how your climate will affect the building.

​

For insulation to be effective, it should work in conjunction with good passive design. For example, if insulation is installed but the house is not properly shaded in summer, built-up heat can be kept inside by the insulation, creating an ‘oven’ effect.
