The appropriate degree of insulation depends on your climate, building construction type, and whether auxiliary heating and/or cooling is to be used. The higher the R value, the higher the level of insulation. How well an insulation product resists heat flow is know as its R value.

Insulation acts as a barrier to heat flow and is essential for keeping your home warm in winter and cool in summer. 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. The first step towards getting a good result from your insulation is to understand how your climate will affect the building.įor insulation to be effective, it should work in conjunction with good passive design. 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). Insulation is used to stop heat inside the home from escaping in winter, and to stop heat outside the home from entering in summer. Insulation is a material that resists or blocks the flow of heat energy. Always follow the manufacturer’s instructions. Some types of insulation should be installed by a professional, while some you can do yourself.They need to be identified and insulated to prevent heat flow and condensation risk. ‘Thermal bridges’ are pathways for heat transfer through components of the floor, walls or roof.All insulation should be installed carefully following the product specifications, to minimise the risk of condensation or fire.Composite insulation combines bulk insulation with a reflective surface. Reflective insulation reflects heat back to where it came from, and if double sided does not re-radiate heat on the opposite side. Bulk insulation uses air pockets within a thick material to slow the flow of heat. There are a wide range of insulation products.The type and R value of insulation that is best suited to your home will depend on your climate and construction type.The ‘total R value’ adds together the R value of the various components of a roof, ceiling, wall or floor, including the insulation.The best orientation for your home is the one that suits your climate zone. Good orientation can significantly improve your comfort and reduce your heating and cooling needs.The performance of any insulation product – how well it resists heat flow – is know as its R value.Insulation is a key part of any passive designed home, helping to keep heat inside the home in winter and outside the home in summer.Insulation is a material that slows or prevents the flow of heat.
