Vertical Sliding Sash Window

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.

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

To further enhance this versatile system, a new ultra-slim Vertical Sliding Sash meeting rail will soon be available. At just 37mm the new, slimmer meeting rail faithfully replicates the appearance of a traditional sash window and adds even greater heritage authenticity to this industry-favourite. When a project demands authenticity, it delivers nothing less than perfection.
