As specialists in period, conservation and listed properties, our replacement sash windows have also been approved for listed and conservation properties by planning officers and architects throughout London and the South East.

Our sash windows are known for their slim section sizes and glazing bars, in keeping with the traditional style of Georgian and Victorian architecture.

Planning officers in some authorities have even approved our double glazed sash windows for listed buildings, as we are still able to maintain the slim section sizes and glazing bars by using highly efficient, slimline double glazing.

Timbawood offers three proven ranges of high specification sash windows, depending on your budget and the requirements of the property:

  • Heritage Range – exact-match windows for listed buildings and stringent conservation areas
  • Conservation Range – for properties in conservation areas and homes of distinction
  • Traditional Range – for period and modern properties
