Just wondering if anyone is getting double glazing windows for enery efficiency and high ceiling (8ft 6in). This is coz they cost approx 5K each, so i am wondering what everyone else has also considered thnx Re: Double glazing windows & high ceiling 3Feb 14, 2009 8:38 pm I asked the sales consultant today about the double glazing windows and he said that they'd cost $10K for the whole house. I had a very long silent moment after what he said Re: Double glazing windows & high ceiling 4Feb 14, 2009 9:06 pm A $5,000 window is called a bifold door...
Builders add large margins to upgrades and window manufacturers who are not used to supplying double glazing - charge high prices. If you are in Melbourne try Burbank Future range - double glazing is standard.

The area of glass open to the outside will severely reduce your energy rating (and make it impossible if you need to go single glazed). The glass will likely need to be site installed with a crane. The only way to minimise the cost and the thickness is to break the expanse up into smaller panes with mullions(vertical piecs of aluminium). But the sheer amount of glass will hamper your energy rating anyway. You may need to look at using Low-E glazing within your double glazing.

We've been solving a similar issue in relation to large windows and double glazing, although nowhere near that large! We have a 3.6m x 2.4m timber framed window facing Nth-NthWest and in order to have it double glazed, it will be set up as 10mm CL TG/14mm air/10.38 ComfortPlus...

I was trying to picture a 17m high floor to ceiling window! That would be impressive!!! By the way...do you think having Low-E glass as the outer pane in a IGU will make a significant difference in terms of reducing heat gain in summer? The particular window we have will have an awning above it to try and shield it as well...but at the moment we've specified ComfortPlus as part of the setup to try and make it more effective...do you think that is a good way to go?

If you're right, Ed, an authoritative reference would be handy as I'll have to ask Stegbar why this was recommended for single glazing units.

Cheers, Casa Hi Casa What that says may well be true... excellent daylight transmission and low reflection, but that has nothing to do with energy efficiency and emissivity. Here's a quote from another source... http://www.greenconsumerguide.com/comme ... &PARENT=19 Quote: \Applications Low-E can be used in double glazing everywhere from the largest office block application to domestic conservatories, windows and doors. Where extra safety or security is required, Low-E toughened or laminated glass can be specified. Low-E is designed for use in double glazing, it is not suitable for single glazing, it can, however, be used as the inner pane in secondary glazing. The coating should, again, face the cavity.

Cheers zeke I can't comment on your specific case Zeke, I would need to see your energy rating and house plan. You windows should be illustrated in WERS on the Stegbar page. I think there is an abundance of "information" on Low-E, Here is a sample... http://www.endibrook.com.au/pdf/LowEGlass_brochure.pdf Quote: LAMINATED AND SINGLE GLAZED (MONOLITHIC) LOW-E* For LAMINATED glass, low-E coatings on surface position (2) or (3) do not produce any improvement in U-Value. The only improvement can be obtained with the coating on surface(4) where it interacts directly with long wave radiation. With this make-up, a 30% U-Value improvement is possible over clear single glazing. I will try to find both pages from Pilkington's site that each recommend 1 - to use it in single glazing & 2 - not to use it in single glazing...
