What is the disadvantage of aluminum windows?

There are so many benefits of using aluminium windows however there is one particular area where aluminium windows are at a dissadvantage to the other composite, uPVC and natural Timber eqivelents.

Aluminium windows are durable, strong and ecconomical so its no surprise they are the most popular and first choice material used for windows in Australia and other countries in similair climate zones however…

Thermal Performance

When it comes to thermal performance aluminium being an alloy has a ver high transfer rate compared to the equivelent uPVC or timber variety.

Aluminium is a very good conductor and therefore has a much faster heat and cold transfer from the external environment to the internal enviroment.

When we consider the overall performance of a window, 70% of the transfer between the external and internal enviroment occurs through the glass or glazing, the remaining 30%  is transferred through the frame.

Best Bang For Buck…

So we know that in any build a good bang for buck will be to improove the 70% glass and glazing as it constitutes the largest thermal transfer in a building. Secondly we can now improve the thermal performance through the frame.

How can we turn this disadvantage to an advantage?

Today we have a newly designed domestic and affordable thermally improved window and door system called ComfortEDGE. This window and door suite hides the frame into the wall so little if any heat or cold can transfur through the frame!

The other benefit of this aluminium window and door design is its aesthetic appeal. Architects love the cleaness of the frames, from inside the walls simply flow onto glass with no frame visible – it really has to be seen to be believed.

The other solution is a thermally broken window that is an external aluminium frame and an internal aluminium frame joined together by a non conductive polyamide strip.

The thermally broken design separates the external environment to the internal environment therefore preventing heat loss or heat gain through the frame.

Conclusion…

Considering the advantages and dissadvantages between the different materials used in windows is the best knowledge to carefully detirmine your solution.

As there are many advantages and dissadvantages with every material you will be sure to find the solution that is right for you.
