Re: Insulating 7 Start + new house 15Jul 12, 2018 1:50 pm alexp79 E.g. I am ordering R1.5 windows (U value of <R0.7) to my house, which will work quite well with my consistent R2.8 wall insulation (without thermal bridging). alexp79 can you share where your windows are coming from, i.e brand and through whom did you order from?

I am ordering Austrian Internorm windows from local distributor (PM me for the details) - tripple glazed KF500 secure profile, alum + PVC, U = 0.67 on average. Quite expensive - costs me approx. A$1.3K per sqm of glazing, but I believe it is really worth it, considering 10 year warranty, quality of the hardware and glazing, etc. You can also consider German Dopfner windows from Laros: http://windows.laros.com.au/, they are a bit cheaper and they have timber + alum options, while U is a bit higher (0.8+).

Thanks for the reply. Will drop you a PM shortly. A$1.3K per sqm is reasonable considering it is triple glazed. Additionally Vitrocsa is about A$2.5K per sqm but that is the premium end of windows.

Be very careful comparing European U-Values, and Australian ones (ie WERS compliant). They are different, with the same window getting a lower rating in Europe than here (Europe assumes a larger window than Aus/US for the test, and so frames are proportionally smaller, and thus contribute less losses) - see http://www.paarhammer.com.au/blog/u-val ... australian Also, when comparing other overseas markets, places like NZ often lists the glazing U value, not the glazing/frame U value (at least in marketing materials) Re: Insulating 7 Start + new house 19Aug 11, 2018 7:32 pm planeguy Be very careful comparing European U-Values, and Australian ones (ie WERS compliant).

E.g. for a frame width of 80 mm, the Australian test window will have only around 7% of more frame when comparing to European test window. For each window, I have U values provided for both glazing and frame+glazing.

Using your assumption of an 80mm frame, the Aus window (by area) is 66% glass, 34% frame. The European window is 78% glass, 22% frame. Now assuming the glass part is like some figures I have found for NZ triple glazed 46mm units (R1.81) that shows the frame is weak spot. Now I am not saying your window choice isn't fantastic, but just be careful not to make a direct comparison of U value when they are not directly comparable. Yes well there solution is to blame everyone else while I a 65yr old woman with major medical problems have to just continue to boil water and wash myself in a bucket… 2 15984 If you make sure all taps inside and out are turned off, what does the water meter show if you leave it for a while. 2 20226 13 6578 |
