Timber-effect uPVC flush sash windows across Lancashire

Boasting a unique sash which sits entirely flush within the window’s frame, flush sash windows never protrude outwards opting instead for a sleek, clean, and historical aesthetic look. This gives the whole window a flat appearance, while still delivering market leading energy efficiency, low maintenance, and peace of mind security.

Flush sash window features

  • Flush sash windows come double or triple glazed for homeowners & trade customers
  • Available in side opening, top opening, and side hung opening styles
  • Flush sitting sash to mirror traditional styles of the 19th century
  • Multi-chambered frames for lower U-values and increased energy efficiency
  • More cost-effective than original timber flush windows
  • Generous number of RAL colour options and tones to create a specific aesthetic
  • 10 Year insurance backed guarantee for homeowners
