A perfect fit and
a premium finish

TRC heritage sash windows use a classic weight and pulley mechanism, and are ideal replacement windows for listed buildings as well as architect-led new developments.

We use traditional putty to secure thin, high-performance Slimlite glass (single- or double-glazed). Slimlite ensures an authentic appearance, and satisfies demand for modern acoustic and thermal performance.

Solid glazing bars come as standard. Each window comprises a number of individual glass panels, giving our heritage sash windows genuine character.

When it comes to safety, angel locks and sash stops are fitted as standard. And restrictors can be fitted 100mm above the mid rail to ensure child safety and the security of your property.

All windows are finished with three coats of spray-applied microporous water-based paint, which ensures the smooth operation and optimum performance of the window.
