Argon Gas New technology

Argon gas is the most common replacement for dehydrated air in double glazed units. It has 34%
lower thermal conductivity than air and can improve U value by up to 30%. It is a simple upgrade
without the complication of additional layers of coatings on glass which gives a tinted finish and
could lead to external condensation.
