  • Specs & Features

    • The sliding sash window profile has a ‘multi chamber’ design, for extra strength and thermal efficiency.
    • The profiles are fabricated into windows either by mechanical fixing or by a specialist welding process. Both methods are equally secure and effective.
    • It is extensively tested for air and water permeability to ensure it withstands the demands of the temperate climate. The careful use of seals, draught proofing strips and drainage slots ensures this is a high performance window.
  • The Sliding Sash Windows

    The traditional timber sliding sash window brings a number of problems. So it was no surprise that many saw the replacement of timber sliding sash windows with new PVC-u versions as an easy choice. It took the latest computer aided 3D design systems, plus considerable investment to achieve the necessary combination of a slim, but strong and durable, frame.

    It has a timeless elegance and beautiful proportions which enhance the appearance of almost any home - period or modern, town or country. It is one of the few windows that can be opened, for ventilation or easy cleaning, without obstructing the exterior, for example a pavement or walkway.
