Argon gas is five times heavier than air, making it more stable and more resistant to temperature changes.
Argon is transparent, no smell and non-toxic. Its thermodynamic properties make it more effective against condensation and the differences of high temperature between inside and outside.
In case of using high performance windows for an area of 100 m2 with 20% glass surface, the level of savings you realize when using a double glazing with argon is 40%. The calculation is performed using TRNSYS ® program for an annual consumption.
