They enable slimmer "non-box" frames, making them perfect for Modern Sash Windows-day openings where a conventional deep box frame will not fit.Performance and Energy Efficiency
A typical misconception is that sash windows are naturally breezy. Tailor-made sash windows negate this through accuracy engineering. Modern bespoke units incorporate:
Slimline Double Glazing: Designed particularly for heritage windows, this supplies the thermal benefits of modern-day glass while keeping the profile thin enough to appear like single glazing.Weatherstripping: Integrated brush seals and rubber gaskets are concealed within the customized profiles to avoid air leakage and rattling.Acoustic Glass: For homes on busy streets, customized windows can be fitted with laminated acoustic glass to significantly decrease sound pollution.Considerations for Conservation Areas and Listed Buildings
