Window and Door Weatherseals for Efficient Homes from Cowdroy

Designing energy efficient homes with minimal power bills.

Energy usage and sustainability is a growing concern in Australia, with home energy consumption a significant contributor to greenhouse gas emissions.

The size and characteristics of Australian homes greatly impacts on household energy use, with the amount of floor space affecting the amount of energy needed to heat or cool a dwelling. The size of homes are increasing, but household sizes in Australia are decreasing.

Between 1994 and 2008, the number of homes with four or more bedrooms rose from 21 per cent to 29 per cent, while the number of one, two and three bedroom homes all decreased. The 2.6 people per household in 2001 is projected to decrease to 2.2 and 2.3 people per household in 2026. This means that more space needs to be heated and cooled per person, requiring more energy.

Weather sealing
Even if your home is well-insulated, heated or cooled air can leak in and out through gaps and cracks. Air leakage accounts for 15-25 per cent of winter heat loss in buildings. Sealing your home against air leaks is one of the simplest upgrades you can undertake to increase your comfort while reducing energy bills and greenhouse gas emissions.

Weather sealing your home is an easy and cheap way of reducing your energy bills. It can save you up to 25 per cent on your heating and cooling bills and is easy and affordable to implement - even for renters.
