    Why uPVC is the Smart Choice Over Timber for Conservation Windows

    uPVC is a favourite for windows because it offers a great combination of quality and security with simplicity of operation and lower cost.

    A great benefit of choosing uPVC replacement windows is their exceptional thermal performance. Modern uPVC incorporates a multi-layered chamber frame, so the heat can’t escape. The low maintenance requirements of uPVC are also attractive to homeowners. Unlike having to protect timber yearly with varnish or paint, uPVC is finished in a protective coating that doesn’t crack or fade. All they need is an occasional wipe down to remove any dirt and keep them looking new for at least 35 years.

    uPVC is highly robust and has shown its ability to withstand strong forces and harsh weathers. As well as secure internal beading, durable stays and handles, and heavy-duty Kenrick shoot-bolt hinges, we fit our heritage uPVC windows with multipoint locking systems that pass strict industry standards.
