Spiral Balanced Timber Sash Windows

Our installers can offer solid timber spiral balanced sash windows crafted from oak, other hardwoods or softwood. Solid timber is susceptible to twisting and movement, which is why we use only high performance timber to minimise the risk of warping. Our precision design and attention to detail in every aspect of manufacturing allows us to create solid timber sashes which will last for years to come.

Choose from two ranges; traditional sliding sash windows hung on weights and pulleys, or wooden sash windows hung on spiral metal balances. Grained, laminated or acrylic foil coated PVC-U in white or cream can be used as an alternative to wood. Additional colours can also be etched into the surface to create a long-lasting bonded paint finish.

  • Bygone Symphony

    Our premiere sash window for when only the very best will do. Wood grained, acrylic foiled with every joint traditionally “butt jointed” construction providing the perfect appearance.

    A rated as standard and because we use 16mm sealed units, filled with Krypton gas we have designed two exclusive sections to add real depth and authenticity to these Bygone sash windows. The internal glazing bar is deeper than standard bars while the external chamfered bar aligns with the traditional putty glazed appearance. The deeper internal beads allow additional hardware choices to be fitted.

    You also have a choice of designs for the external and internal sash horns that are a standard feature, along with deep bottom rails and equal glazing patterns.

  • Bygone Harmony

    Again, A rated but nothing else is standard about this range. Identical profiles (bars) are used on our premiere product including the deeper glazing bars, bead and thin Krypton filled sealed units. The only exception is that the deep bottom rail and sash horns joints are butt jointed; the others are mitred.

    While the standard features of deep bottom rail and equal glazing patterns are included, the external and internal sash horns are chargeable options.

  • Bygone Melody

    For clients who appreciate the quality that Bygone offers, but are unable to justify investing in the Harmony or Melody collections. Or for those who seek to install Bygone windows, with Bygone furniture only at the rear or sides of a building, keeping the premiere windows on the important facades.

    Most of the joints are mitred and as the glazing is C rated 24mm argon units the thinner glazing bar and beads are used.

    Whilst the standard features of deep bottom rail and equal glazing patterns are included, the external and internal sash horns are chargeable options.

Our most affordable range is the Melody collection, which offers the same distinctive Bygone style and quality for a smaller investment. Joints are mitred and the glazing is C rated with thinner glazing bars and beads. Deep bottom rails and equal glazing patterns are included, whilst internal and external sash horns are chargeable extras.
