At Cleartherm Glass Sealed Units 95% of all our products are Argon filled
At Cleartherm we use argon gas as a filler for our insulated glass units. Argon gas is a colorless, odorless and tasteless gas that provides optimum thermal insulation whilst being both non-toxic and inert. Using Argon gas in our products ensures they achieve a higher energy rating compared to units using air.
All of our sealed units hold BS EN1279 Part 3 pass certificates, meaning our sealed units comply with the legal requirements for the testing of rates at which gas leaks from a unit.
