Timber Sash Window Finishes

Our timber range of sash windows is available in a wide range of finishes.The timber frame can be stained in a wide range of colours or painted to any RAL colour. The colour of both the aluminium capping and timber frame can be either the same or different to create a dual colour window. This system give a wide range of options enabling you to custom build the perfect sash window.

External Aluminium Capping

Externally the windows are clad with a thin aluminium capping, this gives the window an extremely hard wearing exterior which helps to extend the life of your new sash windows as well as keeping maintenance down to a minimum.  All of our aluminium products are Polyester powder-coated to a large range of RAL colours making it possible to supply these windows in almost any colour. Powder coating tends to have extremely good colour and gloss retention in exposure to outdoor weather and UV ensuring your new windows will look newer for longer.

You can find out more information on our RAL colour system here.


Our timber windows are coated with a 4 stage paint process from Teknos involving a wood preservative, primer, intermediate coat and topcoat. Tecknos coatings are formularted to keep your products looking attractive year after year, resisting the elements, maintaining appearance and value.

Each layer in the Teknos Aqua system has been carefully formulated both for its specific purpose and to work in synergy with the other products in the system to achieve maximum performance, including:

  • Vacuum impregnation, wood preservative and combi primers product to preserve and prime the wood.
  • Primers to fill the wood's pores and provide an anchor for intermediate or topcoats.
  • Specialist primers and intermediate coats to block and inhibit tannin staining.
  • End grain and construction joint fillers to protect the most vulnerable areas of exposed joinery.
  • Intermediate products to fill the pores of coarser wood species, providing a more uniform surface for top coating.
  • Flexible, micro porous topcoats for an attractive, durable yet flexible surface.
