The Vacuum Glazing Network supplies PassivGlas vacuum insulated glazing from its base at Prenton on the Wirral. The units seal two panes of toughened glass around a micro-thin vacuum layer, giving a pane as slim as 6.15 mm that can be fitted into existing timber frames without replacing them. The company quotes U-values as low as 0.44 W/m²K, which exceeds triple glazing, and UKAS-tested sound reduction of up to Rw 41 dB. Units are toughened as standard, carry a fifteen-year guarantee and are expected to last more than twenty-five years. The product is aimed at heritage buildings and retrofits as well as new build.
Suitable for: upgrading original sash and casement windows in listed buildings and conservation areas without altering sightlines or glazing bars.
Services: PassivGlas vacuum insulated glass units; retrofit glazing for existing timber frames; supply to installers, architects, homeowners and commercial clients.
