Exquisite looks.

Ingenious engineering.

Our windows need no painting and minimal maintenance, they won’t rot or warp and they deliver excellent thermal performance.

It is the only window that will perfectly match the traditional architecture where timber sash and case would have been the original windows.

Why choose sliding sash windows?

  • Features traditional ironmongery, a goal post frame and deep bottom rail to mimic a timber sash and case window
  • Both sashes can be tilted inwards for safe cleaning from inside
  • Available with plant-on astragals or stained glass to replicate your existing windows
  • Double wool pile weather strip and interlocking sash for enhanced draught-proofing
  • Incorporates torso balances to remove the need for cumbersome sash weights and cords
  • Decorative sash horns can be specified externally for added authenticity
  • Fitted with two travel restrictors on the upper sash, to comply with Scottish Building Regulations
  • All windows are reinforced as standard, for optimum strength and thermal performance
  • ‘A’ energy rated as standard, to comply with Scottish Building Regulations
