What is a vertical sliding window?

A verticle sliding window is one that you can open by pushing the frame up rather than out like a more common window. The sliding sash window is becoming more popular because it saves space, has a classic heritage window style and is now available in modern materials.

Are sliding sash windows safe?

Yes, sliding sash windows are very safe. They can be locked securely and are easy to maintain and operate. The strength that modern PVCu and Aluminium provide when combined with double glazing ensures the sliding sash window is very robust.
