Masterframe Sash Windows – The Bygone Collection

The very best sash windows for your home

The Masterframe Bygone Collection retains the character and charm of your home with beautifully finished box sash-style windows.

Aspect Windows are proud members of the exclusive Bygone Masterframe Installer Network and are excited to offer you their range of timeless sash windows.

The collection is designed to meet the latest safety requirements of modern windows according to current building regulations.

Thanks to slim sightlines through both sashes, they seamlessly add a period feel to any modern home.

Equal panes between sashes create the appearance of origin timber sash widows, with a durable-grained acrylic foil offering a stunning finish that mimics that of painted timber.

The Bygone slim integral mullion beautifully replicates an original sash window for those searching for a classic period design.

Patented Timberweld® technology creates joints that are beautifully finished to offer an authentic, timber-like look.

Not only will the FINEO vacuum glazing keep your house warm, but it will also let in 15% more natural light than triple glazing.
