Sash Window Vaccum Glass FAQs

Can vacuum glazing be fitted into existing sash windows?
In many cases, yes. Ultra-slim vacuum glazing units are specifically designed to fit traditional timber sash windows while preserving original sightlines and detailing.
What makes vacuum glazing different from standard double glazing?
Vacuum glazing uses an ultra-thin evacuated cavity instead of a larger air or gas-filled gap. This allows excellent thermal performance in a much slimmer unit, making it ideal for heritage and period properties.
How efficient is vacuum glazing?
Our vacuum insulated glazing units can achieve centre pane U-values of approximately 0.49 W/m²K while maintaining a slim 8mm overall thickness. Vacuum glazing also improves acoustic insulation and reduces outside noise.
Is vacuum glazing suitable for listed buildings?
Vacuum glazing is often considered for listed buildings and conservation properties because its slim profile helps preserve the traditional appearance of original timber windows. Suitability will depend on the property and local authority requirements.
