KSW Window Warehouse was started in 1964 by Dr. Jan-Hendrik Joubert and business partners. We have been known as Krugersdorp Steel Windows since then, as our main business was the manufacturing of quality steel windows and doors. As we started diversifying, we had to change our name to incorporate various other products and services. We are now a proud manufacturer, supplier and installer of quality aluminium, wooden, steel and u-pvc windows and doors. We mainly supply builders and developers, but we cater for the home owner and diy enthusiast also. Jan Grobler( Dr.Joubert’s son in law), joined the business in 1968. He has been the man in charge for the most part of the 70’s, 80’s, 90’s and 2000’s and together with his partner Pieter Booyens, they were the leading force in steel windows and doors on the West-Rand and Gauteng.
