High quality Kömmerling uPVC mock sash windows with run-through horns, serving Stockport, Manchester and Cheshire

Made using the same high quality Kömmerling O70 Gold system as our casement windows, our mock sash windows offer the highest levels of security and energy efficiency, as well as heritage looks. uPVC mock sash windows from Alex Trade achieve the high quality and energy performance specifications necessary for any new build or home refurbishment project.

With timber box styling and slim slight lines, Alex Trade’s range of uPVC sash windows successfully gives installers the very best in terms of authenticity, especially when a run-through sash horn is incorporated – an element unique to us!
