A Quick Look at Bygone’s Unique Sash Window Design Features
If you love the timeless beauty of sash windows but don’t want the draughts, rattles, and upkeep that often come with them, Bygone sash windows are designed with you in mind. They combine traditional craftsmanship with clever modern engineering, so your home can feel warm, secure, and effortlessly stylish. Here are some of the key features that set them apart:
TimberWeld® Joints
Bygone uses TimberWeld® technology to create strong, sealed butt-jointed corners that look just like classic timber joinery. The result is a sash window that looks authentic while staying robust and weatherproof for years to come.
39mm Slim Midrail
With a slim midrail measuring only 39mm, these sash windows let more natural light flood into your rooms while still keeping the elegant proportions that make period windows so attractive.
Deep Bottom Rail
That reassuringly solid deep bottom rail doesn’t just look right—it helps give the window balance and presence, echoing the style of traditional timber sashes you’d find in period homes.
Concealed Trickle Vents
Nobody wants modern vents spoiling a heritage look. Bygone has solved this by concealing trickle vents within the frame, so you can enjoy discreet background ventilation without compromising the window’s appearance.
Authentic Hardware
From classic sash lifts to traditional pole eyes, every hardware option is carefully chosen to look the part while giving you the smooth operation and reliability of modern fittings.
Bygone Wins
With Bygone, you don’t have to choose between heritage charm and everyday comfort. These sash windows bring elegance, warmth, and convenience together, perfect for homeowners who want windows that truly look the part while making life at home that little bit easier.
