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