Key Benefits of PassivGlas Vacuum Glazing
SafeGuard’s PassivGlas delivers superior performance through innovative design and advanced materials
- Smarter energy performance - Achieves U-values as low as 0.44 W/m²K, providing outstanding thermal insulation and helping maintain comfortable indoor temperatures all year round.
- Slim profile, big flexibility - Glass thickness from 6.15 mm in single PassivGlas VIG to 28 mm+ in PassivGlas Ultimate – ideal for heritage buildings, retrofits and new builds.
- Toughened safety vacuum glazing - Specifically engineered as a superior replacement for single and double glazed units, combining high performance with modern safety standards.
- Quieter, more comfortable spaces - The vacuum layer minimises sound transmission, with UKAS-tested sound reduction up to Rw 41 dB for a calmer indoor environment.
- Triple-glazed performance in a monolithic unit - Enjoy the energy performance of triple glazing without the bulk and weight of a traditional triple-glazed unit.
- Built to last - Expected life of 25+ years, with a 15-year guarantee for added peace of mind.
- Supports net zero goals - A high-performance alternative to conventional double glazing, ideal if you’re investing in glass that aligns with UK carbon net-zero 2050 ambitions.
