Re: PVCu Double glazing
Snap Shot, we've been in this house for nearly 8 years now and it still doesn't feel like home to me. Possibly because someone else has lived in it first, always had new houses in the UK.
Have had it painted inside and out, put heat pumps in upstairs, changed the ensuite and laundry, put some new carpet in and it still doesn't feel like my home.
We are limited to what we can afford to do with only having the one income. Considering going back to midwifery after 6 years away from it as I've tried to get on two courses, one as a trainee anaesthetic technician and the other to retrain as a nurse. No wanted, thank you very much. Frustrated and down-hearted are how I'd describe myself.

Re: PVCu Double glazing
Are most of the homes built in the last 10 years now with double glazing?

Re: PVCu Double glazing
All homes built within the last ten years (at least) have to have double glazing to comply with the building code. However double glazing in un-thermally broken aluminium joinery are a waste of time as the aluminium is a fantastic conductor of heat. My new house is single glazed and wooden joinery, much warmer than the massive aluminium doors and double glazing in my old house, and looks better too

Re: PVCu Double glazing
I don't believe double-glazing is a requirement in the housing code, at least not in the North Island and possibly all of New Zealand. Our builder told us back in 2011 that in the Auckland region you can use Low-E single-paned glass. Whether you must use double-glazing or not depends on the overall thermal efficiency of the building and insulation used, the size of the windows in relation to walls, and their aspect. He also told us in his experience the Low E coating is not that long lasting.
Quick Guide Building Code requirements: house insulation - Department of Building and Housing
Having looked at innumerable older homes, renovated homes, and newly built homes, I can say that it's rare to find a house in Auckland with double glazing built before 2009 or so. Even as the new codes were put into place around that time, building consents that were approved just before the new regulations came into effect were of course exempt and those houses were completed a year or two later. Because many were built by developers, they were not inclined to spend just a little more to make the house more comfortable.
When Auckland houses do have double-glazing the great majority are in thermally unbroken aluminium frames, which have an inferior insulation rating to timber frames and bring on condensation to a greater or lesser extent depending on sun and wind exposure.
Because our house is a rimu clad cottage we installed timber windows and sliders with double-glazing. We get no condensation and the house is extremely quiet, also due to the fact that we used the highest rated insulation on walls, roof, and underfloor. The opening on our sliders is very, very wide, as we installed enormous doors. We think it was a better solution than bifolds which don't seal as well, plus our deck need no clearance for the doors to open. Timber framed windows are very thermally efficient, but they do require maintenance.

What are the building requirements for double glazing?
The energy efficiency building requirements of the 3rd Edition of Clause H1 of the New Zealand building code were introduced on 31 October 2007, making double glazing necessary in most new houses to meet the new glazing R-valve of 0.26.
It still may be possible to use single glazing by using a heat loss calculation (Calculation Method - NZS4218:2004) that allows the insulation in one part of a house to be traded against the insulation in another part of the house. You should discuss this with your designer as they will be required to provide calculations demonstrating compliance with NZS4218:2004 with any building consent application.
Note, the new requirements of the 3rd Edition of Clause H1 only apply to building consent applications, applied for on or after 31 October 2007.

Re: PVCu Double glazing
We used Homerit to for the frames all good use German profiles some of our frames had to be strengthened as they are 3m tall and had thicker glass due to being in a high wind zone

Re: PVCu Double glazing
We decided last year we wanted our windows on the cold side of the house double glazing, a total of 5 windows and a front door. The windows that are on that side of the house are original to the house which was built in 1956, they're beautiful wooden ones but they're not too draft proof and the glass is as thin as greenhouse glass.
So we had 4 options, UPVC, Retrofitted DG glass in the existing frame, standard Aluminium DG or thermally broken aluminium DG.
Here's the rough prices I've been quoted including fitting
UPVC $8900
Aluminium DG $10,000
Aluminium thermally broken $10,500
Retrofit (just the 5 windows) $9300
So the company run/owned by Brits using materials brought in from Germany is cheaper than the kiwi companies using locally sourced materials. Plus, the UPVC is a far better product.
