Gas-Filled Sealed Units for Superior Insulation

The gas fill inside your sealed unit makes a significant difference to thermal performance. Argon gas is the most popular choice for UK homes, offering around 34% better insulation than air-filled units at an affordable price.

For heritage properties requiring slimline units, krypton gas delivers excellent performance in narrower cavities. We also offer xenon gas for specialist commercial applications.

All our gas-filled units are manufactured to BS EN 1279-3 standards with a minimum 90% gas fill level, ensuring long-lasting thermal efficiency and compliance with Building Regulations Part L.
