Our timber sash windows are known for their authentic slim section sizes and slender glazing bars, which are faithful to the traditional style of Georgian and Victorian architecture. As specialists in period, conservation and listed properties, we use slimline double glazing from as slim as 11mm which looks just like single glazing, and has been approved for conservation and listed properties throughout London and the South East. 

Our three proven ranges of high specification sash windows are:

  • Heritage Range – Exact-match windows for listed buildings and stringent conservation areas
