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
