Aluminium window construction

If you are looking at good quality aluminium windows and doors it is important to have a general understanding about the product range before you become overwhelmed with industry jargon. What follows is some information about aluminium window construction that will give you a head start.



Window types

There are 5 basic window types:

  1. Sliding
  2. Top-hung
  3. Side-hung
  4. Double-hung
  5. Bi-fold
  6. Louvre

Window and door units are generally called windows by manufacturers in Australia and are available in standard aluminium, architectural profiles (a chunkier profile).

When selecting a window style, consideration should be given to:

  • Which one looks best on the outside when opened
  • Which opening mechanism works best for the situation and is easy to use
  • How important is their fully opened surface area for ventilation
  • The best shape and size considering the wall space
  • How much they are exposed to violent weather, how good is their weather proofing and are they able to meet Bushfire requirements in your local area - level 1,2,3 or flame zone

Wintec energy rated windows & doors

With modern design, utilising quality seals & hardware componentry, Wintec window and door products meet the high demands for energy efficiency and weather performance in today's market. Some key features to consider with regard to energy efficiency include:

Economy: One important and very practical reason to select Wintec high performance windows is to reduce the annual cost of heating and cooling your home. This makes good economic sense and also contributes to the national effort to reduce the environmental impact of non-renewable energy use.

Good Sealing of Sash and Frame: Heat leaves or enters a home through gaps and cracks around sashes and frames. WERS-rated windows must satisfy Australian Standard AS 2047-1999 for air infiltration performance. Wintec windows and doors easily exceed the requirements of the Standard and achieve air leakage rates less than 0.5 litres per second per square metre of window area. Various seal types are used to help achieve these better ratings.

Structural and Water Resistance: The hollow aluminium extrusions used in Wintec windows and doors not only aid in their energy efficiency, but they give superior performance in water penetration resistance and structural rigidity. In addition, Wintec windows and doors incorporate a baffle in the drainage system that allows water to flow out but restricts air flowing through the window or door frame. Therefore reducing the energy loss normally encountered through drain holes. The Difference between a window that just meets AS 2047 (5 L/s.m2 air infiltration) and a Wintec window is approximately half a heating star. The effect on cooling performance is much less.
