Inert gas filling of sealed units improves the thermal efficiency of glazing. Argon and Krypton are denser than air and act as an additional thermal barrier to heat escape.

Argon, a gas widely chosen for its cost-effectiveness and ability to enhance U-values by up to 0.2W/m2.K, is a practical choice for various double and triple-glazing cavities to significant.

Krypton, on the other hand, finds its niche in specialist glazing, particularly in units with narrow cavities of 8-12mm. Its use in these units helps achieve superior U-values.

Modern high-volume sealed unit production requires Argon gas filling online during the production process. The latest incarnation of online gas filling is a tandem gas press that enables two units to be argon-filled simultaneously. Regency Glass has invested in two of these high-speed production lines.

Once the units have been gas-filled, it is essential to seal them quickly to prevent gas loss. Regency has invested in two Bystronic High-speed line sealing robots that immediately seal the unit, giving excellent gas volume rates of +90%.

We test daily using one of our two Sparklike non-invasive gas testers. These are set up for Argon and Krypton and are calibrated annually by the manufacturer in Finland under our EN1279 accreditation.
