Symphony - Vertical Sliding Windows

Symphony is our top of the range UPVC sash window and probably the best currently available on the market. With an unrivalled specification featuring the best of the best, it is no surprise that virtually every optional extra you may wish for is fitted as standard on a Bygone Symphony window.

Key specification:
Authentic wood grain textured acrylic foil across all profiles
Traditional “butt jointed” vertical and sealed corners for an authentic construction appearance.
Exclusive ‘Bygone only, Super-Slim’ 39mm Transom, sure to impress the most critical conservation officer.
Slimline 16mm WER “A rated” sealed units, filled with Krypton gas which affords deeper internal georgian bars, glazing beads and chamfered external bars offering the ‘putty-line’ traditional glazed appearance.
Fully “secured by design” compliant, police approved and the preferred Sash Windows specification due to the fully steel reinforced sashes and the exclusive Bygone Stainless Steel clawed cam catches with porcelain ball design.
