Vertical Sliding Box Sash Windows

We are the only local manufacturer of sliding sash windows. The other trade suppliers and fabricators buy them in.

When you buy windows and doors from someone who is doing the same, you are at the end of the chain. You are as far away from control as you could be. When you buy PVC vertical sliding sash windows from World Group, you're dealing direct with the manufacturer - we are in control the whole way.

Our PVC sliding sash windows come with colours suited hardware to match our wider range of windows and doors. The run through sash horn offers a seamless decorative horn, with no unsightly join that you find on 'clip on' alternatives.

A full colour range is available to match in with other windows and doors so that your home has the same elegant look throughout.
