A window style that is synonymous with the Georgian and Victorian eras, vertical sliders are also known by a host of other names, such as sash windows or box windows. They feature a timeless design which will significantly enhance the visual appeal of any type of home, all whilst keeping your home warm and secure.

Timeless style for the a seamless match with any home

Vertical sliding windows are named as such for the way they are operated; they are opened and closed via a sash that slides vertically, allowing you to easily inject as little or as much air into your home as you’d like. Whilst their appearance emulates that of traditional timber sliding windows, meaning they’re a great fit for older properties, their design is what you would call timeless and therefore easily lends itself to contemporary properties just as well.

Stunning Finish

We offer a variety of colours from each end of the colour spectrum and woodgrain finishes, all of which are renowned for their pristine quality.

Taking the best of traditional styling and combining it with modern performance

Fully utilising the natural insulation qualities of uPVC and moulding it into an innovative ultra-efficient profile means the thermal performance of your home will improve dramatically. If you’re looking to reduce your energy consumption, keep your home warm and lower your heating bills, these windows will enable you to do so. Plus, their stylish ovolo shape ensures the exterior of your home will instantly look more appealing.

With their ability to be tilted inwards, you can wipe down these low maintenance uPVC windows from within the comfort of your own home. Unlike traditional timber variants, you needn’t worry about them succumbing to rot either because uPVC is immune from it. As uPVC is also incredibly durable, they’ll last for years to come. Fully weatherproof and great for keeping out external noise, our vertical sliders are the epitome of style and substance.
