Gas filling the cavity inside sealed units gives added thermal insulation.
Argon is the most commonly used gas due to cost, Argon is 1% of the atmosphere and is readily available from several suppliers in gas or liquid form. It is twice as dense as air and thus slows the heat transfer across the cavity of the sealed unit, giving extra thermal insulation.
Argon gas, from our on-site Argon storage tanks is transferred into the IGU cavity during processing using either the ‘on-line’ gas press facilities or, for shaped or decorative units, we use our ‘off-line’ gas filler.
Regency Glass Argon Gas fill all insulated glass units as standard.
