Krypton as a filling gas – efficient insulation for modern insulating gas windows
The energy efficiency of buildings depends largely on the quality of the glazing. Insulating gas windows, especially double-glazed windows, are now a central component of modern thermal insulation measures. In addition to the glass structure used, the filling gas in the space between the panes plays a decisive role in thermal performance.
Krypton as a filling gas offers considerable advantages over conventional gases such as argon or air. Due to its lower thermal conductivity, krypton significantly improves the heat transfer coefficient (U-value) of insulating glazing. This leads to a noticeable reduction in heating energy requirements and thus contributes to COâ‚‚ savings and climate protection.
Optimal thermal insulation with krypton in double-glazed windows
By using krypton as a filling gas, the space between the panes in double-glazed windows can be made more compact without compromising insulation performance. Krypton-filled double glazing thus achieves thermal properties that were previously only possible with heavier and more expensive triple glazing.
In addition, krypton's higher density also improves sound insulation compared to lighter filling gases such as argon. This makes krypton the ideal choice for sophisticated building envelopes that need to offer both high energy efficiency and acoustic comfort.
Messer – the industry standard for krypton in insulating glazing systems
Messer offers high-purity krypton as a filling gas for industrial use in flat glass processing, particularly in the manufacture of technically sophisticated double-glazed windows and insulating gas windows. Our gases meet the highest quality requirements for purity, moisture content, and delivery specifications as required in the field of automated glass filling.
With our robust gas supply and technical consulting services, we support manufacturers in the efficient implementation of krypton-based filling systems – from small-batch production to fully automated large-scale manufacturing.
