Full height windows and doors would expand more than 6mm and they will tend to bind and may be impossible to open and close. This is air temperature. There is also the consideration of radiant heat, and white colour would be minimal but darker colours absorb radiant heat and surface temperatures in excess of 70 degrees could double that expansion. PVC melts at 160 degrees and temperatures approaching that will make the PVC warp and sag. This is why PVC is totally unsuitable for bushfire areas where temperatures well exceed the melting point of PVC, and the first thing to happen will be that the glazing beads holding the glass in place will melt and the glass will fall out. Over time and with UV exposure the PVC will become brittle and difficult to maintain. Were those issues you experienced often in Sydney's climate? What would you expect from the manufacturers locally when that happens? Lastly, should an expansion joint be used on either side of the frame? I'm in Melbourne, yes I experienced those issues. I think your supplier would need to accommodate the expansion all around the frame.
