1. The Georgian Era (1714-- 1837)

Georgian sash windows are defined by their "six-over-six" configuration. Because glass-making technology at the time might just produce small panes, several pieces of glass were held together by thick wood glazing bars. This Period Property Windows focused on balance and mathematical proportion above all else.

Materials: Timber vs. Modern Alternatives

Single GlazingLow; susceptible to heat lossAuthentic; initial appearance
Slim-lite Double GlazingHigh; mimics single glassMaintains thin glazing bars
Basic Double GlazingVery HighNeeds much thicker frames
Secondary GlazingHighInternal; doesn't impact exterior

  • Cleaning up the Pulley: A drop of oil on the pulley wheel once a year guarantees a smooth, quiet operation.
