We're building a house and I requested a quote from the builder for double glazing all windows and glass doors (except the window in the garage). The windows are aluminium as we need to meet BAL29 bushfire requirements. The majority of our windows are double hung. To upgrade to double glazing for double hung windows, we needed to go the more premium range of windows. Otherwise would need to change all window styles. I like double hung for the benefits of air flow. Our windows I believe will be 5-6-5mm Argon filled. They will also require toughened glass for bushfire requirements. When compared to the original windows in the house (its a project home design), the additional cost to upgrade over the existing cost of windows will be $25K for 19 windows, 1 sliding door and 1 stacker door. Does this sound reasonable or nuts? Thanks in advance, Re: Thermally Broken Windows - You don't need them!!! 13Jun 20, 2017 2:11 pm Hmm, on the other side my friend yesterday got a quote from YY - US$10K for 23 windows TOTAL, all 5-12A-5 (mostly sliding and chained winder awnings though, but also including 1 sliding and 1 stacker door). This will be around AUD$17K delivered and customs+GST paid. I guess 6 mm is not much of a air space, you would need at least 12 mm to get benefit from double glazing. Re: Thermally Broken Windows - You don't need them!!! 14Jun 20, 2017 2:20 pm Wow that was quick. I guess to get them from the US it would be much cheaper as they are more readily available and used alot more commonly over there (colder weather). I know where I'm from (europe) they are not at all expensive... standard costing. However, due to our building circumstance, they're coming through the builder and the price I've quote is the delta to standard windows. The actual cost is $33K. Just hard to know if its what I should expect here. Based on the wers website, I'm happy that a 5-6-5mm argon will give us sufficient improvement in both comfort and energy benefits. Otherwise the past 4 months of trying to convince my husband has been an utter waste of time! Thanks for the feedback.

To mangle a common saying, premium is in the eye of the beholder. The double-glazed windows in our home are coming in at around $150K. Provided they meet your efficiency and BAL requirements, your windows look like a bargain to me. Re: Thermally Broken Windows - You don't need them!!! 20Jun 21, 2017 11:01 am Thank you arcadelt. Thats an incredible cost for glazing. However, I've seen your pictures and wow - impressive. Thanks for the feedback. I actually looked further into it last night, and based on the WERS website, the benefits of going to a 5-6-5 over the standard range the builder would install normally is a 25-30% improvement on cooling and 20-25% improvement on heating and for Uw values, it reduced from 6.3 to 4.4, SHGC reduced from 0.74 to 0.53. Another important one for me was air flow and that reduced from 4.45 to 0.62. The best benefit I saw was on the sliding doors and stacker doors for up to 40% improvement on heating, and a reduction in Uw value to 3.8. Overall, this will improve the overall efficiency of the house dramatically and improve the comfort of air-flow through the windows both hot and cold. The one thing I can't stand is the breeze I feel in my bedroom at night in winter. (currently single glazed) Where we live we get as high as 47 (this summer) and as low as -2 (3 degrees this morning!). So I needed something to help with both heat and cold. It meant compromising a little, but its a balance. To go to greater argon gaps, only improves the heat and cooling efficiency marginally by a 2-3% (probably not worth the extra cost) and the greatest improvement on cooling efficiency was to tint the windows, which I didn't want to do. As you said, in the eye of the beholder, and I'm confident that we will definitely see the benefits, despite the cost. I have an investment property and tenants moved out recently.
