 Our Environment



A well insulated home can reduce your heating and cooling bills and help you to be healthier and more comfortable all year round.


What is insulation?

Insulation acts as a barrier to heat loss and heat gain, particularly in ceilings, roofs, walls and floors.


There are two main types of insulation:

  • Bulk insulation helps keep heat in or out by stopping heat from escaping or entering.
  • Reflective insulation helps keep your home cool in summer by deflecting radiant heat.


Benefits of Insulation

Insulation helps to:

  • reduce the need to use your mechanical heating and cooling systems, saving money on your energy bills
  • improve weatherproofing of your home
  • reduce moisture problems like condensation
  • some types of insulation can also make your home more soundproof.


What to insulate

Ceilings: If your ceiling isn't insulated, you could lose 35 per cent of your winter heating via the roof.


Walls: Uninsulated walls can increase heat loss in winter by 10 to 20 per cent.


Floors: Some types of floors can also lose heat unnecessarily up to 20 per cent of your winter heat.


Verandah & Garages: Verandah roofs and garages might benefit from insulation if you spend a lot of time in these areas, especially if you are heating or cooling them.
