What is Double Glazing?

The basic concept for double-glazed windows is that by trapping a layer of air or gas – a natural insulator – between two sheets of glass, the amount of heat leaving your home is dramatically cut.

At Turkingtons we use utilise the most modern materials available. Our market leading double glazing now incorporates a 90% Argon gas fill cavity, Planitherm Total + heat reflective coating and a warm edge spacer bar. These are fitted into our Superior robust multi-chambered reinforced uPVC frame.
