After a remarkable amount of research, thought and discussion we have finally decided on and ordered our windows – 23 of them. Due to budget constraints and the need to avoid regular future maintenance we ordered white aluminium frames rather than timber. Hopefully they’ll look nice and work well. There are different grades: residential, semi-commercial and commercial, which look quite different – the commercial grade is more chunky. We’ve mainly gone for residential but ordered a semi-commercial stacker door for the rear deck. There are also different styles: casement, sliding, louvre and awning.
Other considerations that we had to take into account is that some windows have restricted opening (by law) so that children don’t fall out of them. This came about because a few parents placed bunk-beds next to fully old opening windows resulting in the inevitable. This has led to all new developments having bedroom windows with restrictive opening (irrespective of there being a alternative fire exit for example). Also first-floor exterior window cleaning is a consideration – some styles are easier than others.
Many years ago I built a system called BASIX for the NSW Department of Planning. This is now used for all substantial residential building projects to assess the environmental effect of the work (thermal considerations, energy usage and water usage). As a result of my good work, we’ve been required to apply UV filters and awnings to the north-facing windows.
We’re using BWG for the windows. They, like all the other providers have a huge backlog of orders (because everyone in Sydney is renovating thanks to the lowering interest rates and high house prices), so it’s going to take 8 weeks to fulfill the order. We’re hoping that this won’t delay the project…
