Sliding Sash Windows

Sliding sash windows are made of one or more movable 'sashes', with the option of creating individual panes with cottage bars. Double-glazed sash windows add elegance to any home and are the ideal way to inject a touch of period grandeur. Two draught-free, movable sash frames made from UPVC provide superb ventilation options. You can even upgrade to acoustic sound-reducing glass. In Upminster, Hornchurch, Romford, Brentwood, Chigwell, Loughton, Woodford, Chelmsford, and Billericay, AGS is a leading sliding sash window supplier.
