Vertical Slider

When we set out to design a sliding sash window, we knew we had to make something really special. Our Vertical Slider had to have the authentic appearance of a timber sash but none of the drawbacks. It had to be better than the original. We’re pleased to say we’ve done it, but don’t just take our word for it: the Spectus Vertical Slider is widely regarded as the best PVC-U sliding sash window there is.

Features

  • Compatible with off the shelf hardware
  • Customisable to meet the highest security standards
  • Wide choice of colours and woodgrain finishes
  • Trickle or glazed in vents
  • Standard or fully reinforced to Spectus recommendations.

Dimensions

  • A 128mm outerframe matches timber sash dimensions, making installation simple
  • Windows can be made up to a maximum size of 1600mm wide and 3000mm high
  • Large and small sash profiles give equal sightlines to the top and bottom sashes
  • 150mm and 210mm cills
  • 10mm/20mm/50mm frame packers.

Appearance

  • Authentic ovolo shape to the frame, bead, sash and cill
  • Optional Georgian bars, sash horns, weather bars and a deep bottom rail designed specifically to provide that period look
  • Flush gaskets mimic traditional glazing
  • Approved by many planning boards, even for use in conservation areas.

Energy Efficiency

  • Designed to achieve a Window Energy Rating of Band ‘A’ with 24mm sealed units
  • Draughts prevented with pile seals to the sash and outerframe.

Function

  • Both sliding sashes can tilt inwards for easy cleaning
  • Smooth operating balance mechanisms.

Our Vertical Slider is Kitemarked to BS EN 12608, certified to PAS 24 and approved by the British Board of Agrément. We manufacture under a quality management system that conforms to BS EN ISO 9001 and are recognised for responsible sourcing under BES 6001.
