Conventional – Traditional Box Sash Window

Our Conventional Box Sash windows are designed to replicate the traditional form, to keep in line with period properties and conservational area appearance. Our improved insulation minimises condensation, draughts and heat loss in comparison to single glazed Sash windows and can look identical to the windows you are looking to replace. By using engineered timber, this allows us to make frames slimmer and lighter with the use of modern interpretations of the cords and counterweights for improved functionality.

  • Traditional appearance
  • Triple draught strips fitted internally
  • High insulation properties
  • Reduced heat transmission
  • Internally fitted glass for improved security

Conventional – Traditional Slim Box Sash Window

Our Conventional Slim Box Sash windows are ideal for replacement windows where internal shutters or decorative features restrict the depth of new windows due to the slim design. This design is also perfect for bay window replacements and they are quickly becoming one of the most popular window types in the U.K. In addition they are ideal for conservation areas as the sash horns and glazing bars are available in different widths to match existing window designs.

  • Traditional appearance
  • Slim design
  • High levels of insulation
  • Low maintenance
  • Extensive warranties

Production Process

Our Timber sash windows are made from either hardwood or softwood engineered timber, fully finished in wide range of colors and glazing options.  We can also produce both unfinished and primed elements of sash window ready for further treatment or painting on site.
