Supplied and fitted

We do not make vertical sliding sash windows ourselves. They are made by specialist sash manufacturers to the sizes we measure and fitted by our own FENSA-registered team.

ECOSlide

  • Both sashes slide up and down on a balanced mechanism and stay at any height
  • The sashes tilt inwards so the outside glass can be cleaned from indoors
  • A+ energy rated as standard, with a U-value of 1.3
  • Georgian or astragal bars, bay, arched and swept-head shapes
  • Woodgrain finishes, colour outside with white inside, or spray painted to almost any RAL colour

Legacy

  • Run-through sash horns and a deep bottom rail for a traditional timber look
  • Optional mechanical corner joints in place of welded mitres
  • Slide and tilt for easy cleaning
  • Astragal bars and an ovolo weather bar
  • Colour-matched trickle vents to meet Part F of the Building Regulations
