A few nice Aluminium Windows images I found:

This northerly view from the back of my childhood house was taken when I was a teenager and starting to get interested in meteorology. I grew up on this council estate in south Hatfield which was built in 1956. It was designed by architect Lionel Brett (who became 4th Viscount Esher), and was innovative in that the terraced houses curved around the contours of the land in a series of sinuous crescents. They were warm and cosy and had sizeable gardens compared with modern-day council housing. The main distinctive feature was the low-angle single-pitch roof, constructed from timber overlain with aluminium cladding. Each terrace had a single modular roof extending over its entire length.

Unfortunately this design approximated to a crude aerofoil section which was spectacularly demonstrated during a severe gale on the night of 3rd-4th November 1957 when virtually all the houses facing in a westerly direction had their entire roof length lifted clean off and flung for distances of up to a 100 metres away. In this photo, the houses visible in the lower left all lost their roofs, which ended up in the gardens to the right. The houses which faced east (of which ours was fortunately one) were unaffected, as the ‘leading edge’ of the roof section was not facing into the wind.
