Double Glazing Two Story House

Hi all we are building a story house are we are required to do few windows and stacker doors double glazed by Basix. The builder charges $5000 to do these job and when I ask they do $10000 to do all windows double glazed. Does it worth double glazing all the house or just where required by Basix? We have 13 Windows and 3 Stacker doors with 3 slides each Please help friends. I have to tell them in 2 days

    I would do double glazed windows in the bedrooms at least, esp. if you are facing the road or a neighbour.

    In living areas you wouldn't really care about noise at night, low-E/comfort glass would do fine.

    How many windows and doors are "few"?

    Not all double glazing is the same. In fact, some is amazing and some is very very poor. Some is better for noise and some better for heat transfer. You need to do some research and find out what you are getting.

    If you can afford it, go for it. We double glazed all the windows in our place years ago. Keeps heat out in summer (for a few days), cold out in winter and also keeps neighbor noise down. As mentioned above do your homework. If you will live in your home for many years then you should save on heating and cooling costs. Others near us run their air con all the time but we don't really need to except for the hottest days a few times a year.

    We just finished a multi year double glazing project. Now that it is finished 100% and every halogen is now an led the house temperature is a lot more stable (ie dont come home to a hot house).

      Hi Friend, Do you have any idea the double glazing cost double than a standard window installation?

      •  

        Rylock Windows & Doors quoted me last year about $2000 a window for old frame removal, and installing new frame and double glazed 4mm/12mm gap/4mm.

        From a materials perspective, double glazing would cost double because the frame has to be twice (or more) as thick and use twice as much glass (though each pane thinner, as normally you'd use 6.38mm for comfort glass and the like).

        Installation should cost the same though, so its possible your builder is overcharging you for double glazed, OR he gets a really good price on single glazed.

          Thank you so much for your response mate so they quote $2000 for a single (2 slides) window?

            @CThomas: The local window place had a standard amount for installation - tiered on size (and if they were sliding doors).

            There is a fair bit involved removing an old window - the old window frames were really heavy (I was able to sell them for $50-$200 each for the wooden ones on Gumtree - the aluminium ones I gave away).

            @CThomas: On average, per double hung window 1.2m across, yes. Not casement windows.

    Our bedroom is west facing so we put in a big glass door onto our balcony so we could open up the bedroom to airflow in the summer evenings. The door is double glazed and eco glass. We were replacing our old weatherboards with colorbond sheets so we took the opportunity to also put in the highest rating insulation in the walls as well. The bedroom is cooler and the noise has been cut down considerably. For our linkover door we just went with the ecoglass.

    Hope these links help.

    Very well worth the money spent to double glaze particularly for summer as double storey will literally be like oven when you come back from work.

    We rented a double storey and hated it..come back home from work and cant even get in the bedroom to relax/change ! Few hours of aircon to just cool down !!

    •  

      Greatly depends on the design of the double storey home and location. We have fantastic airflow in ours, no aircon, ceiling fans only which don't get used a lot, crossflow ventilation in 3 of the 4 upstairs bedrooms. We live within a km of the coast, mid north coast NSW. We also have a whirly bird vent on our roof which I think can make a big difference (as well as insulation in ceiling). Majority of our windows are tinted, single glazed, even south facing windows are tinted (which was a mistake as it makes one downstairs room too dark).

        " within a km of the coast, mid north coast NSW." That explains your experience…unfortunately for people who are inland i think double storey sucks big time but land cost makes them handy.

        •  

          Yeah, that's why I stated that design and location plays a big part and the OP doesnt state their location. A lot of double storey homes can have pokey little bedrooms upstairs, no crossflow, low ceilings, poor insulation etc. Design and location makes a massive difference.

    Direction of windows, proximity to noise, shaded areas.

    MS paint this sheet.
