Vertical Sliding Sash Windows
With many traditionally built properties the only true option is to install Vertical Sliding Sash Windows.
The original sliders were supported by ropes and pulley with a cast iron weight. Today the modern uPVC vertical slider is controlled by galvanised spring balances to make the opening and closing finger light. We usually fit restrictors to the top sash to give additional security, with ring pulls to the top sash for ease of opening.
All vertical sliding sashes can be tilted inwards to make cleaning a simple task.
