Browse Forums Windows & Doors Re: Windows design suggestion 6Sep 11, 2013 10:35 am Double glazed aluminium awning windows are your most cost and energy-efficient option. Timber windows require a lot more maintenance, and the top-hinged awning window has a full seal when closed. PVC are seriously expensive as they tend to be handled by small importers direct to retail, and your result with a double glazed awning window will be excellent. I'm not sure about double glazed sliding doors;double-glazed sliding windows are not a reasonable option as there is no permanent seal on the sliding mechanism except for an industrial level that is prohibitive for residential. Great to see so much care in the choice of windows, as for many Australians this is not an aspect of building new that gets the attention it deserves. Re: Windows design suggestion 7Sep 19, 2013 9:55 am Hi Matergabiae, My post is too late to help with the original question but some advice for the benefit of people reading this thread later... Aluminium window frames are cost effective and low mainenance, but they actually reduce the energy efficiency of glass. Aluminium is a great conductor of heat (think frypans etc). That's why they introduced thermally-broken frames, where there is a section of plastic or other material to separate the inner and outer sections of the aluminium frame. Wooden frames are actually quite energy efficient, but do require regular painting maintenance over the life of the house. uPVC - plastic frames have quite good energy efficiency, but different people have different views on their look and feel. If you want a good energy efficient window, always ensure it has a Low-E coating, and in more challenging environments, go for double glazing with a Low-E. Ensure there is external shading for windows exposed to summer sun & dont be afraid to use different glass for different orientations. Eg having solar control (tint) in the glass for windows facing West for example Hope this helps!

Aluminium is a great conductor of heat (think frypans etc). That's why they introduced thermally-broken frames, where there is a section of plastic or other material to separate the inner and outer sections of the aluminium frame. All frames reduce the energy efficiency of the glass, aluminium is an excellent conductor, so as a material it is a poor insulator. Glass being the ultimate leveller, to achieve an efficient window in aluminium requires good design, not just thermally broken, but good thermal shielding, minimal surface exposure etc.. Viridian Glass If you want a good energy efficient window, always ensure it has a Low-E coating, and in more challenging environments, go for double glazing with a Low-E. Ensure there is external shading for windows exposed to summer sun & dont be afraid to use different glass for different orientations. Eg having solar control (tint) in the glass for windows facing West for example In any environment suffering heat loss through conduction, there is no substitute for double glazing. Low E has its uses and advantages, but for heat loss it cannot replace double glazing with anywhere near the performance of 2 pieces of glass and an air gap. The results in WERS demonstrate that, but they don't show the whole picture, because Low-E is effective only with radiant heat, and double glazing only with conducted heat. I agree with the use of different performance glasses for different orientations.
