In 1979 Window Machinery Sales Limited was the first Company to sell PVC Machinery in the UK. David Stockton-Chalk and Derek Bonnard have been a significant part of not only PVC but Glass and Aluminium machinery since those early days. The Company has proudly built up strong relationships with German & Italian manufacturers who they have worked closely with to develop total UK marketplace solutions. In 1993 the trading name of Promac (“Professional Machinery”) was initiated because this more correctly reflected the new fully automated machinery that major fabricators in the UK were now investing in.
Promac is the UK market leader for over 40 years in the supply of machinery to the Double Glazing Industry
