This is mainly to say that I envy you guys and girls who work on double glazing the majority of the time. The standard windows and frames here in oz are p**s poor, they flex, are of poor quality so a bugger to clean etc etc. I did my first double glazing job a month back which was internals and externals, it was a joy to work on. I've just been back today doing just the externals and got done so much quicker than the standard windows here. I asked her where she got them from as they are quality windows, surprise surprise they are from a German company that are based in one of the suburbs of Perth.
