Option of painting and renovating

The frames need to be renovated at regular intervals. A coating applied professionally through the use of modern water-based materials can last as long as 10 years. For the purposes of renovation and protection of the frame, modern eco-friendly varnishes can be applied to the surface by anyone. The option to re-paint traditional box sash windows also allows for a change in colour whenever you choose, which cannot be done with PVC frames.

The colours we offer are varied and you can choose them from a colour card we provide for you.

Natural look of wood

They have a natural look – especially those with a visible timber texture. They are particularly suitable for houses built using traditional methods, with wooden finishings and details, outfitted with wooden furniture. Wood sash window frames and jambs also have better thermal insulation properties than plastic or aluminium ones.
