Which performs better, soft coat or hard coat? Also, do you know which i still expected to be fully functional after a few decades?
Browse Forums Eco Living Re: Double glazing 21Mar 26, 2009 10:26 pm Jennysmith A basic low-e coating can help to reduce heat loss and at the same time allows the room to be warmed by direct sunshine. There are two types of low-e coatings available, "hard-coat" and "soft-coat". Hard-coat glass is manufactured by applying molten tin to the glass surface as the glass sheets are being manufactured. The tin bonds to the surface of the glass and forms a relatively thick coating. Soft-coat glass uses vacuum deposition to apply a metallic coating to the glass surface as an additional manufacturing step. While the metallic film is very thin compared to the hard coat it does require special handling and storage as the surface is easily damaged. Which performs better, soft coat or hard coat? Also, do you know which i still expected to be fully functional after a few decades?

I think i'll spend that on getting wall insulation and PV system to pay for the electricity the AC uses.

I think i'll spend that on getting wall insulation and PV system to pay for the electricity the AC uses. Wall insulation may not be the best idea as heat will always take the path of least resistance - namely the windows. You also need to find out or work out how much of your energy bill you can save with the improved windows and compare against how big a PV system you need to run the AC. PV systems are not cheap either.

Maybe if we win the lotto I can rip out the windows and replace them later I know the PV sytem isn't cheap...but it's cheaper (marginally) than 37k of windows and we can put it on down the track after the house is finished and we are bleeding less money. We get an awesome breeze where we are so really only expect to use the AC when it's really hot but when it's really hot here you really need the AC Built Liberty 42 - Handover 26th Feb 2010 forum thread: https://forum.homeone.com.au/viewtopic.php?f=31&t=17243 Re: Double glazing 27May 17, 2009 10:00 am Nightshade I had to ditch the dbl glazing...I just couldn't justify such a huge amt of money.

Mind you, $37k is a big price for double glazing - you must have a lot of windows. Our average price would be under $20,000. Have you checked the U value and resultant energy loss for single glazed versus the PV systems energy gain versus cost of each?

Tel. 1800 326 326 Re: Double glazing 28May 17, 2009 10:29 am Not really..I may never get the PV either I tried calling the window company to see how much it'd cost and if it would be feasible to replace the single glazed with double glazed after the house was built. Mustn't be any requests for dbl glazing in BNE as they knew which house it was for straight away and refused to speak to me So completely given up on the whole idea. So only small things for us: - water tank - solar hot water - wall insulation Built Liberty 42 - Handover 26th Feb 2010 forum thread: https://forum.homeone.com.au/viewtopic.php?f=31&t=17243 Re: Double glazing 29May 17, 2009 11:22 am IMO double glazing for Brisbane is not required. Temperture differences are not great enough for long enough top justify the costs. Eaves, louvres, cross flow ventilation, cool gardens and good house design will be far more beneficial. As for PV running the air con - donlt even consider it. Your PV will only generate enough electricity to cover your fridges and minimum daily lighting costs at best. A 1kw PV system will generate around 3.7kw per day. Re: Double glazing 30May 17, 2009 12:44 pm Our energy report hasn't come back yet, but we've been told to expect alot of dbl. glazing. Spoke to the window manufacturer directly (supplier of our builder) and he quoted around $15K extra. He recommended doing the entire house no matter what the energy report states, particularly the up stairs. Some windows can be spared (laundry for example). Having been inside a house in summer with full dbl. glazing I am totally convinced. I too was shocked at the increase, but have come to accept it and no doubt will feel better about it come the first cold/hot day. I'm assuming the $37K increase is due not only to the glass, but the need for entirely new frames?? Re: Double glazing 31May 17, 2009 4:51 pm Yak_chat ... was looking at least a 4KW system + we will have solar hot water which is more than enough in my current house..hoping will be enough in the new one. Bris still gets quite hot and I've been in houses with dbl glazing and the sound insulation was also a major benefit we liked. Norb - Not sure...I couldn't get any more detail out of anyone except 37k. Thought we could do some selective glazing instead but have just given up now. Still think it's pretty steep as an upgrade price. I'm jealous of your 15k quote though...I def would have put them in at that price.
