We had discussions with most Melbourne project home builders before deciding on our house. For many of the sales staff it was the first time anyone had asked about double glazed windows. At first most of them quoted ridiculous prices ... but when our final shortlist actually went back to the office and checked it usually came in at $2000-$5000 extra for a 22-28sq house (aluminium). Our extra glazing cost came to around $5000 (27sq living area) by the time the windows were changed from single-glazed sliding aluminium to double-glazed aluminium awning and we upgraded the glass in sliding doors to a 6mm laminate. When making the cost/function compromise the WERS site is your friend! http://www.wers.net I'm hoping that the 25-50% improvement in thermal performance is going to justify the initial cost many years down the track! Lyn. Re: Double Glazing 28Jun 10, 2007 8:04 pm Hi newbie Lyn,
My target is a Uw, which is a whole window rating, of less than 3 W/m2.K. As long as get this window rating I will be happy. Oh, and the cost is reasonable and it looks nice. I guess this means double glazing, low-e and a decent frame.

Welcome Lyn this feels like Déjà vu apologies for not welcoming you earlier. Quote: We had discussions with most Melbourne project home builders before deciding on our house.

You are right , most people don't know much about double glazing, including people in sales in the building industry. In fact I was looking at 2 identical homes for sale in Stockland’s Hidden Grove development in Keysborough the other day, both homes facing the lake, both for sale. One was 100% double glazed (4mm or 6mm air gap) the other single glazed. Not a mention in either sales flyer not a mention by the sales guy . And it was not easy to spot with black spacers as the gap between the panes was very narrow. So I do concur - sales people are not au fait with double glazing. And to take your point futher, unfortunately many sales people (and others) are unfamiliar with the improved framing available. e.g. uPVC and thermally broken aluminium . There is much written much about uPVC elsewhere in this forum but suffice to say it is the future in windows in Australia, 2 out of 3 people who visit EcoClassic's showroom in Hallam prefer uPVC (and EcoClassic sells aluminium AND thermally broken aluminium AND uPVC ) . But taking your point even further, I will make sure EcoClassic commences immediately to educate their builders' sales teams... thanks. Oh and uPVC is no different to any other material - you have to be careful what you buy and where. I have heard of glass falling out of rubber glazed aluminium windows in an occupied home when the screws holding a sash together sheared due to incorrect torque during assembly (this is exacerbated by the weight of the glass and this was only single glazed in a small sash ) - not a problem with uPVC which is mostly welded nor a problem with a silicon glazed aluminium window as in the case of EcoClassic's aluminium window. Quote: Our extra glazing cost came to around $5000 (27sq living area) by the time the windows were changed from single-glazed sliding aluminium to double-glazed aluminium awning and we upgraded the glass in sliding doors to a 6mm laminate. Great idea, I think the prices quoted would be of great value if you can provide a list of your windows and doors saying which are double glazed and single glazed and laminated. A before and after price would be good. I can ask EcoClassic to list theirs alongside Perhaps other like minded people on the forum can obtain comparable quotes and we can all get an idea of market prices. Oh, and to know your window supplier would be good too... Quote: When making the cost/function compromise the WERS site is your friend! http://www.wers.net As you know these systems take time to update... EcoClassic's results have been available for some time now and will soon appear in WERS, FirstRate, BASIX etc... In the mean time anyone can email EcoClassic for a PDF copy of the Energy Rating for a window. Quote: I'm hoping that the 25-50% improvement in thermal performance is going to justify the initial cost many years down the track! my prediction. In 2 years, double glazing will be the majority glazing... and uPVC in 5 years - And in 15 years triple glazing In any race there are leaders and followers but if you are not leading or following, then you are not even in the race. I expect many manufacturers who want to survive will follow EcoClassic's lead I know some started even earlier - Trend Windows moved into uPVC recently. Again, welcome Lyn and if you are in Melbourne – please drop into EcoClassic’s showroom you will be made very welcome. Looking forward to hearing from you again… Thanks Ed If I write "I" please read "We"! Be good. Re: Double Glazing 31Jun 11, 2007 9:31 am It is simular here in NZ,
Real estate sales people don't even mention the double glazing. Builders and architects try to ignore demands for double glazing. In some cases the customers need to get very firm with them in order to get the double glazing in. Not to mention thermally broken frames, most so called "builders" would not have heard about it. Whether it is AUS or NZ, the building industry is still run by a majority of narrow minded, backwards thinking ignorants with very low understanding of basic physics and "true" economy. But there is hope here in NZ as double glazing will be compulary from 2008 but there is still a lot of work to do with the frames and the hardware. Re: Double Glazing 32Jun 11, 2007 10:24 am Ed, good to see someone passionate about windows. Between you and windowexpert and others we are learning a lot. Thanks for sharing your expertise and experience. I think when it comes to double glazing many consumers are naive and retails’ eyes light up when a consumer asks for double glazing. I'm now learning that double glazing doesn't have to be frightfully expensive and more people should consider it. It's a decent one-off cost that gives you better thermal comfort and lower energy bills FOREVER.
Hopefully other window experts will join and continue the education of the masses. I know I still want to learn more. It’s more than academic. I'm designing my own house and all my windows will be double glazed. I like slim, clean lines and ultra low maintenance items at a reasonable price with a Uw rating of less than 3 W/m2.K. I'm also after two large (4 m x floor-to-ceiling) sliding doors that will live side by side (at a 120 degree angle) up one storey that look out onto a view. I'm after a 2 m fixed pane and a 2 m sliding door. Same requirement as for the windows plus flush floor between inside and the balcony. The balcony is covered so rain should never reach the door itself. I've rambled on as usual, but these days all I'm thinking about is my new house design and I've turned into a knowledge sponge.

Re: Double Glazing 35Jun 12, 2007 10:12 am It really depends on the number and size of windows & doors and style.
Tell me: - (Refer to our website for standard sizes) 1. Number and size of windows by configuration and glass type (obscure, toughened, tinted, Low-E) 2. Number and size of sliding doors, 3. Number and size of of French doors 4. Number and size of bifold doors (great product - well below market price) 5. Colour required (outside, white inside) 6. Number of flyscreens 7. Type of construction (brick veneer, weatherboard, lightweight, foam etc.). KD hardwood reveals are standard if required. I will PM you a firm quote but feel free to publish on the forum if you like. Delivery would be a small issue from Melbourne - but I think you will be happy with the overall cost.

Tel. 1800 326 326 Re: Double Glazing 37Jun 12, 2007 11:16 am Hi Bud977... Low-E is low emissivity
ie From http://www.glassonline.com/infoserv/dictionary/584.html Commonly known as "low-E" glass and often used in double and triple glazing units, this window glass has a special thin-film metallic or oxide coating which allows the passage of short-wave solar energy into a building but prevents long-wave energy produced by heating systems and lighting from escaping outside. Low-E glass thus allows light to enter while also providing thermal insulation. Has been claimed to work in single glazing - but really does not to any worthwhile extent, but is great in double glazing.

It is metal - a thin layer of Silver makes glass totally reflective - we call it a mirror - Low-E is higher tech than that... almost invisible...
