We have fitted composite windows in the past and they are high quality aluminium cladded windows , they were great to work with, very thermally efficient but quite expensive, but we feel the life span abs efficiency is far greater than uPVC .
There aren't a great amount of suppliers but the thermal break in these windows are well worth the money.
