Vertical Sliding Box Sash Windows

When you want to capture the classic, stylish looks of Georgian sliding windows, without the associated risks of drafts and poor security, a vertical sliding box sash window from World Group provides an ideal solution. Our advanced PVC-u system features triple seals for exceptional draft proofing, an anti-jemmy bar and reinforced hardware for optimum security, plus a slide-and-tilt mechanism to ensure your windows can be easily cleaned and maintained.

Our premium vertical sliding box sash window system lets you enjoy the sophisticated style of the Georgian era, with all the performance benefits of PVC-u materials of the modern age. The cutting-edge design features sliding upper and lower window panes, both of which tilt to enable easy cleaning from within your home

An anti-jemmy security bar gives excellent protection against break-ins, whilst triple brush seals keep out the drafts. There's an overhead vent to supply constant fresh air, low-line beads and gaskets to improve sight lines, and a choice of high-quality hardware to suit your tastes. The styling includes decorative horns and ovolo beading, and you can complete the traditional look with Georgian bar fixings.
