— Recognising the period

Five marks of a true
Georgian sash.

Georgian sashes are defined by symmetry and proportion. Get any one of these wrong and the whole elevation reads cheap.
  1. 01

    Six-over-six

    A traditional window style featuring six individual glass panes in the upper sash and six in the lower sash.

  2. 02

    Slim glazing bars

    22mm period bead, offered as stick-on or individual glazing bars — modern uPVC is double that width.

  3. 03

    Square top rail

    No drip moulding — that arrives in the Victorian era.

  4. 04

    Double glazed units

    Standard 24mm units, or a slim 12/14mm profile where the reveal is tight.

  5. 05

    Boxed weight system

    No spring balances on Georgian elevations. Weights, every time.

— Six-over-six geometry

Three columns,
two rows, perfect symmetry.

The Georgian glazing pattern is a study in proportion. Each pane is taller than wide, in the same ratio as the elevation itself.

  5. 05

    Made from Tricoya.

— Georgian FAQ

Common questions about
georgian.

Yes — we laser-measure and replicate the full bar profile including putty rebate, with through-glass bars available for the correct shadow line. However, we also offer a more common — and more affordable — way of manufacturing, using stick-on glazing bars.

Yes, listed building consent will be required to carry out the work. We handle the application as part of the survey.

Most conservation areas in London do not require consent, as long as the windows are copied like-for-like — though it's always worth checking with the local authority. Listed buildings are different and do require consent (see above).
