What makes Bygone Windows so unique?
The Bygone Collection sash window is one of the best PVC-U options available, particularly the Bygone Symphony, which stands out for those seeking premium quality. This range includes nearly every optional extra as standard and features FINEO vacuum-insulating glazing, achieving an impressive U-value of 1.2.
There are three models in the range: Melody, Harmony, and Symphony. Each profile boasts a woodgrain-textured acrylic foil, with all corners constructed in a traditional “butt jointed” manner for an attractive appearance.
Notable features of the collection include patented Timberweld construction for timber-like authenticity, the exclusive Bygone ‘Super-Slim’ 39mm external transom, and 18mm sealed units filled with Krypton gas. These elements allow for deeper internal Georgian bars and create a classic ‘putty-line’ glazed look.
With steel-reinforced sashes and stainless-steel Bygone clawed cam catches, the Bygone Collection meets “Secured by Design” standards, making it police-approved and a top choice for consumers.
