Browse Forums Windows & Doors Re: Double Glazing costs 41Sep 11, 2010 10:12 pm There is wide variation between manufacturers. Timber cost ~ UPVC cost Follow this link: viewtopic.php?p=288135#p288135 Re: Double Glazing costs 42Sep 14, 2010 3:58 pm We never made any aluminium or wooden windows, only upvc, but on average, for our clients, the biggest contributor to cost of the window is the cost of the IGU (double glazing unit). There are other inputs like profile, hardware, etc. It also depends on how the business is managed: you can have a lean business with productivity improvements passed to the consumer or a mismanaged one where the customers pays more, and ultimately you won't know until you compare the quotes. So in choosing aluminium or timber or upvc framed windows, I recommend you decide on what your priorities are - aesthetics, energy efficiency, security, sound insulation (or even a combination) rather than be motivated by cost. The cost to upgrade to low - e glass is normally a few thousand dollars, but ordinarily people just get it on their sunrooms or one or two sides of the house. Also consider using tinted glass instead of low-e, some of our customers who had both preferred tinted for getting rid of the glare.

For double glazed units to be the major cost in a window means that the d/g units are too dear compared to other cost components.

Re: Double Glazing costs 47Sep 14, 2010 6:43 pm dymonite69 Window quality has a lot to do with frame construction and hardware. Design and quality of manufacture is everything... dymonite69 Do the Shake and rattle test. Windows are already tested under laboratory conditions, just ask for the terrain rating, the test is far more stringent than a shake and rattle. But quality is evident if you know what to look for and you should look at the finished article, not just rely on the test. A certain major manufacturer took a window from a finished home and tested it in a lab, it failed miserably, they decided that it failed because it was "used", so they took a new one from the production line to the lab... it too failed miserably... in spite of the "test" window having passed the original test.

Tel. 1800 326 326 Re: Double Glazing costs 48Sep 15, 2010 1:14 pm This is all a bit complicated. I understand that quality differences affect pricing. However normally there is a sweet-spot with best value for money as opposed to products where you pay premium for branding. I'd think this applies to windows just like every other product...? All builders I looked at had standard glazing without upgrade option listed (and some have extensive option lists). Is this because there is so little demand for double glazing? Is it because the cost is so high that owners abandon the idea? Seems we have a few suppliers here (hi guys ) - would you be able to provide a cost comparison based on a sample house (say 40sq) with typical window configuration? What I'd like to know is the base price for single glazed, sliding windows (the standard?) and the price difference to double glazed uPVC tilt & turn windows with low-e coating on two sides of the home. Lets assume standard window sizes and no fancy extra features. Cheers, Razer Re: Double Glazing costs 49Sep 15, 2010 2:25 pm We don't supply single glazed, or sliding windows so my knowledge of prices there would be a guess. Your question depends on a lot of things like numbers of windows and doors and styles, there is no typical house. If you supply a plan and we will quote it for you and you can publish it here.

Windows and doors installed Re: Double Glazing costs 52Sep 17, 2010 3:21 pm It's very hard to provide a quote based on the parameters of the size of the house, a lot of the homes we supply have 'feature' (large) glazing areas, and the majority of our customers have architect designed homes, limited only by imagination (they can get creative with glass and windows too)! When we tried to apply statistical methods to identifying pricing determination for a 'typical' house, the results were not robust at any reasonable confidence interval. Rather, if you can provide the glazing area of your home it would be a better indicator of the window cost. Also, there is a positive linear relationship between the number of opening items (as opposed to fixed items) and cost. Fixed (non - opening) items are less expensive. Also, with our quoting software, some window styles are cheaper than others, with the most expensive item being bifolds. With upvc frames, bifolds represent a challenge in reliability and smoothness of operation, especially with double glazing adding weight to sashes, and we have found the need to use specialised hardware, which is more expensive than for other window types. If you want double glazing for noise insulation it will probably be dearer, since acoustic engineers generally recommend thick laminated, assymetric glazing, where a secondary system is not an option, and thick glass is more expensive.

Not much choice over here - you get offered aluminium frames and plain float glass, take it or leave it. Current builder wants to tack on ducted refriegerate aircon for $17K. That sort of money should pay for cavity wall insulation and upgrade to double glazing with $ savings over a lifetime due to reduced energy consumption.

Windows and doors installed Thanks Fred for the info and the business... (though I don't know who you are) The Vantage aluminium window is inferior to EcoTech (aluminium) in both strength (N rating) and energy performance - and almost 3x the price... I agree there is no economic reason for choosing the thermally broken product (EcoTherm) with current energy prices... it's main benefit is to have a different colour inside and outside. EcoTherm has the same U value as PVC, so generally the same can be said for PVC (EcoPlus) which has the same energy performance as EcoTherm, (the thermally broken product), both when compared to EcoClassic's EcoTech aluminium, have a small benefit which can't be justified economically under current energy prices. It's a matter of personal choice. Thanks again, Ed "ECOECO" At 'EcoEco', we design windows, we design the best windows, we do it for you, so that when you’re happy we are happy. Tel. 1800 326 326 Re: Double Glazing costs 55Sep 18, 2010 7:07 am Razer So, its about 50% more for double glazing? Ed - how does uPVC compare? 50% is pretty rough, as you can see, one supplier was almost 3x our price - their single glazed product would be perhaps twice the price of our double glazed product. On the price of PVC, I can't specifically say on the above info as it's not quite detailed enough, and I would need Fred's permission to dig out the specifics. I think perhaps add 30% - 50% for PVC (that's our PVC versus our aluminium, brands vary HUGELY in price). I can say that when you move from single to double glazing your benefit is to halve the energy conducted, when you move from aluminium (EcoTech) to PVC (EcoPlus), or thermally broken aluminium (EcoTherm), your benefit is 20% of the improvement you made when you chose double glazing (that is using EcoTech). Some manufacturers' thermally broken windows don't even match the performance of EcoTech which are non-thermally broken windows.

Re: Double Glazing costs 60Oct 06, 2010 11:45 am parawolf Curious one i've heard, but haven't seen written much about is noise insulation through the use of different thickness glass in a DG arrangement. Can this be discussed quickly/disproven/elaborated and costed say per sqm vs standard D/G? We do 4mm float x 9mm air x 8.76mm laminated for an extra $154/m2 (Incl. GST). The difference to the STC/Rw is around 3 compared to say 4/12/4. Plus, since we use silicone glazing, this will add to the security in a huge way, making break-ins almost impossible via a glass panel.
