They permit slimmer "non-box" frames, making them ideal for modern openings where a conventional deep box frame won't fit.Performance and Energy Efficiency
A common mistaken belief is that sash windows are naturally breezy. Custom-made Sash Window Refurbishment windows negate this through precision engineering. Modern bespoke systems integrate:
