Insulation is a material that slows or prevents the flow of heat. 

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. 

The performance of any insulation product – how well it resists heat flow – is know as its R value. The higher the R value, the higher the level of insulation. 

Good orientation can significantly improve your comfort and reduce your heating and cooling needs. The best orientation for your home is the one that suits your climate zone. 

The ‘total R value’ adds together the R value of the various components of a roof, ceiling, wall or floor, including the insulation. 

The type and R value of insulation that is best suited to your home will depend on your climate and construction type. 

There are a wide range of insulation products. Bulk insulation uses air pockets within a thick material to slow the flow of heat. Reflective insulation reflects heat back to where it came from, and if double sided does not re-radiate heat on the opposite side. Composite insulation combines bulk insulation with a reflective surface. 

All insulation should be installed carefully following the product specifications, to minimise the risk of condensation or fire. 

‘Thermal bridges’ are pathways for heat transfer through components of the floor, walls or roof. They need to be identified and insulated to prevent heat flow and condensation risk. 

Some types of insulation should be installed by a professional, while some you can do yourself. Always follow the manufacturer’s instructions.
