Our ultra-thin heritage double glazing is specifically designed for listed buildings and properties in conservation areas. We offer sightlines as minimal as 6mm, allowing our units to fit seamlessly into original frames while maintaining the property's historic character. We're happy to assess your specific project requirements.
Our Authentic SlimLite™ range offers sightlines as minimal as 6mm for 7mm rebates, making them the slimmest available on the market. Our SlimVac vacuum glazing units have an 11-12mm sightline with just 8.3mm total thickness.
Performance depends on your specific requirements and conservation constraints. Our krypton-filled units achieve U-values from 1.4 W/m²K, while our SlimVac vacuum glazing offers exceptional 0.4 W/m²K performance.
