This RDH Technical Bulletin covers the use of argon gas to improve thermal performance in insulated glass units (IGUs).
Argon gas is used within IGUs to improve thermal performance. Windows have a relatively low R-value to begin with, so every improvement—including low-e coatings, gas fills, and extra glazing layers— is important. As we strive for more energy-efficient buildings, enhancements such as using argon gas fill will become more commonplace. Based on a number of argon fill projects RDH has reviewed, the initial and ongoing argon fill in IGUs is variable.
