Hi all,
Does anyone have an idea to upgrade to the triple glazed window? I have 2 windows (1.8x1.8m and 1.8x1.2m) that I want to have triple glazed. Appreciate all of your advice.
P.S. I'm building with PD
Browse Forums Windows & Doors Re: Cost of triple glazed window 6Jul 08, 2014 8:11 pm I've not heard of triple glazing being used for sound insulation; doesn't mean there's not a point, just that it's usually mentioned for stupidly cold places. It should be possible to research whether there's a point, gut-feel says it wouldn't be worth doing over double glazing but frankly I gots no idea. The cost is going tombe verynhigh, due to such low demand here. You may even have to import. Re: Cost of triple glazed window 7Jul 08, 2014 9:03 pm You need to speak to professionals as it's not just windows that are the things that let the noise in, also double and triple glazed windows designed for thermal resistance are not as good for the same type of window designed for sound suppression Sent from my iPhone using ones and zeros and 4G Re: Cost of triple glazed window 9Jul 08, 2014 9:49 pm Who is the window manufacturer for PD? A&L do most of them or Stegbar, you can call either of them, A&L will even do an assessment to see what is needed. If you Google for soundproof windows you will get some local Vic companies that do retro fitting to existing windows and also do double glaze and claim 70% reductions in noise but no idea on the price. There is a window guy on here as well that do DG but not sure if for sound or thermal Sent from my iPhone using ones and zeros and 4G Re: Cost of triple glazed window 10Jul 09, 2014 2:33 am Double glazing with maximum gap possible in your frame in between is sufficient. Ideally 50mm at minimum. Make sure you have sound insulation and also upgraded gyprock if budget allows as noise will still come in through the weakest link. Re: Cost of triple glazed window 11Jul 09, 2014 9:58 am We had to upgrade the thickness of our glass as part of the "estate rules" due to a proposed new road. Not sure of the effectiveness yet as we're only at brickwork stage lol. First time build-Commodore Homes- Brabham WA KEYS 12/12/14.

They cant just go in any window - they need special frames with larger glazing pockets (as your looking at an incredibly thick glass unit) Look at alternatives like Laminates (which are the best for sound reduction) Source: I'm an estimator for a construction company in the window sector Re: Cost of triple glazed window 13Jul 09, 2014 11:31 am I live on a busy street now and I'm building on the same street. Next door in fact! I've gone for VLam Hush glass (http://www.viridianglass.com.au/Product ... =Specifier) on my master bedroom windows. I'll see how that goes. If it's disastrous, I'll be putting roller shutter on the windows too. They don't look very friendly, but they are super effective. My parents have roller shutters on every window and they are great and killing the noise from the street. You could double glaze with laminate if it's not too cost prohibitive, but triple glazing seems exorbitant and will be very expensive. My two cents!

You should post this question in the Window and Door Section... viewforum.php?f=23 Someone like Ed from Ecoclassic windows or one of the others would be able to give you a pro's opinion or at least add to the info already supplied by LaceyM. Stewie Re: Cost of triple glazed window 15Jul 10, 2014 12:13 pm I'm curious about this too, as I'm also building on a busy road, but haven't planned on any sound-proofing. All we're doing is putting the living area and master at the back of the house. I'm not sure if this will be enough. All we have at the front is the garage and a guest bedroom. Next in are the studies, and then the more frequently used rooms. Re: Cost of triple glazed window 16Jul 10, 2014 2:19 pm The thicker the glass (overall), the better the sound stopping power. Windows are rated according to the number of decibels they stop (for any given glazing specification). Our window with standard glazing rates Rw 34.5, so it stops 34.5 decibels (4/12/4) Double and triple glazing make little difference, it's all about the glass mass... Laminated glass adds another decibel. 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: Cost of triple glazed window 17Jul 10, 2014 3:17 pm Hello All, With Kommerling pvc windows we offer, we can easily make triple glazed windows. The triple glazed system is compliant with 44Rw and there are acoustic test reports certiying this level of performance, offering jointly a high level of acoustic comfort while being virtually a perfect insulator (if compared to single glazed ordinary aluminium windows). For our return customers only who are very senstitive to cold, we regularly upgrade them to triple glazing free of charge in bedrooms or south facing areas, and we haven't had anyone reject this offer. First time customers can normally upgrade to triple glazing for an extra $50-100 per window depending on size (note we do not offer single glazing, so the cost difference refers to double to triple rather than single to triple). However, in most cases, double glazing with thick, heavy acoustic laminated glass will generally offer a better performance/ per $ spent value for money than triple glazing. The thinnest acoustic glass we offer is 6.38 lam and the thickest is 19.76 lam. The 10.38/20 air or argon or krypton or xenon/6.38 combination is very effective and is rated 42Rw in our most popular tilt & turn window, while for customers who are even more senstive we offer 12.38/24air or argon or krypton or xenon /8.38 rated 45Rw and even thicker glass combinations are available upto 54mm total thickness of double glazed unit. It is all about working out the best value for money (the thicker the glass, the more expensive the window, but at the same time thicker glass performs better) Our customers with triple glazed windows in Sydney and Canberra enjoy very energy efficient homes, with some customers reporting surprisingly low electricity bills compared to their neighbours/families. Triple glazing has been very effective at reducing heat GAIN on the west facing windows. We have used 4mm tough low-e/ air gap of choice/ 5mm tinted/ air gap of choice/ 4mm clear glass with fantastic feedback. The greenhouse effect does not have time to kick in, because heat gain is reduced so much that by the time there is transfer of heat to the third pane, it is night time. So where it is not possible to have an outside form of shading, targeted triple glazing is not a bad idea, and may prove very useful.

Any window (almost) can take thicker glass. Ours rates Rw39 with 8.76/9/4 (tested), and more with thicker glass. The most energy efficient air gap is 12mm... for air and argon, it is 6mm for krypton. Gaps above 16mm show a deterioration in heat insulation due to eddy currents. Your ear can differentiate a noticeable change only of 10 decibels or more... and in any case your building fabric, roof, ceiling and walls will let sound through. Buy only as much as you need, and to do that, in existing windows, I suggest you plug your window with a doona with a backboard, and see if that stops the unwanted sound, if not, you are wasting your money because the sound is entering from elsewhere 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.

Many manufacturers/ window suppliers only offer one gap so naturally the only air gap they offer becomes the best gap. There are a couple of published papers that suggest that the benefits of reduced thermal transfer keep accumulating, albeit at a decreased RATE, from 16mm of air gap upto 20mm.

Except the air gap... the study was done by Berkley and published in the ASHRAE Handbook 2001... 12mm is optimum gap for air and argon... so less is worse and more is worse...
