Conventional sash windows are typically related to being “cold.” Nevertheless, sliding sash windows harrow can install “discreet” draught-proofing systems. These involves machining grooves into the timber components to house weather-pile strips, considerably lowering heat loss without changing the window's look.
2. Acoustic Insulation
Expert fitters can encourage on acoustic glass or different densities of panes to decrease street sound— a typical requirement for city-dwellers in period homes.

Sash windows present unique security challenges. Experts set up strengthened sash stops that enable the window to be left slightly open for ventilation while remaining locked against intruders.
Indicators of Quality Workmanship

Noticeable rot in the sill
Water ingress
Partial or full frame replacement
Condensed glass
