Retain heat in your home

Keep yourself warm and comfortable, and reduce your heating costs at the same time.

The ability to retain heat in your home and reduce your energy consumption is affected by three key factors:

  1. Insulation
  2. Draught proofing
  3. Window design, orientation and coverings

Heat loss without insulation


Insulation is the most effective way to improve the comfort and energy efficiency of your home. A fully insulated home means you will spend less on heating in winter and cooling in summer.

Uninsulated ceilings, walls and even floors can account for significant heat losses.

What is draught proofing

Draught proofing

Draught proofing, or sealing up gaps and cracks, will minimise heat loss from your home and reduce your heating bills.

Draughts and unwanted air leaks not only make your home uncomfortable, but they can also increase your heating costs.

Common sources of draughts include skirting boards and architraves, exhaust fans and vents and external doors.

Window design, orientation and coverings

Windows play a big role in retaining heat in your home.
A single pane of glass can lose almost 10 times as much heat as the same area of insulated wall.

Window design, orientation and coverings all play a part in your window's effectiveness.
Fortunately, there are simple steps you can take to reduce heat loss through your windows.
