We have continued to manufacture uPVC windows and doors since then as a supply only company. In the year 2000, Profab Window Installation was established as separate company to take care of the installation of windows and doors manufactured by ourselves. As we are the only uPVC window manufacturer in Daventry, we believe it gives all of our customers peace of mind. We manufacture a market leading profile supplied to us by Kommerling UK, extruded in Germany, who are Europe's market leaders in profile extrusion, and there is no comparison in quality.
