Woodgrain Finished Options

A wide range of woodgrain and coloured-foil options are available for either or both internal and external faces or even differing frames.

Dual-colour is a popular choice and reflects traditional frames where the outside is painted a different colour to the interior, allowing for greater flexibility in interior decorating.

Below shows all the colours available in our uPVC Windows and Doors.
