thisplace.com.au - Energy Saving for Windows

Correctly chosen, well positioned and protected windows will save you money and increase the comfort of your home all year round.

Windows are the critical to the overall energy efficiency of a home - as much as 40% of heat entering in summer and 30% of heat lost in winter occurs through the window.

Windows:
The climatic region and the direction windows and other glazed areas face are important factors in determining the appropriate window for your home.

Summer Shading:
It is more effective to block the sun's heat from reaching the glass than to deal with the problem once the heat has entered your home.

Shading north facing windows:
North facing windows should be shaded with devices that provide protection against the summer sun and, where required, allow the sun to enter the house in winter. This requires a degree of flexibility which can be achieved.

Shading east and west facing windows:
Eastern and Western windows should be well shaded from the morning and afternoon summer sun.

Shading for other windows:
Windows facing north-east or north-west are best shaded by adjustable awnings or blinds, combined with horizontal shading such as eaves and pergolas.

Preventing winter heat loss:
Appropriate window protection can reduce heat loss through windows by up to half, reducing your heating bills significantly.

Double glazing:
This type of window consists of two panes of glass separated by a sealed air space, typically between 6mm and 20mm. A minimum air space width of 9m m is recommended.
