We are able to supply and fit double glazed sealed units which are filled with an inert gas called argon.
How does argon gas help to keep my home insulated?
The ‘gap’ between the glass in a double glazed unit has to contain something – it is filled in an environment which naturally contains air and so one option is just to have a unit containing regular air. However, despite air providing moderate insulation there are some inert noble gases which do the job better.
One such gas is Argon. As well as being non-flammable, non-reactive and colourless, it also has no odour. Perhaps most importantly it provides the best insulation of the inert gases often used in sealed window units. The convection inside the space between the glass is slowed down. Some brands such as Pilkington K-Glass combine argon gas with a softcoat glass. We can install hardwood, aluminium or UPVC units with the added benefits that argon gas bring.
All sealed unit brands we install which make use of argon gas have passed BS EN1279 part 3 which is a test of the gas concentration within the sealed units and a measure of how much gas leaks out of the units. It needs to remain above 80% concentration in order for the insulation to remain effective. The standards set within EN1279 part 3 ensure that only units which leak less than 1% per year are deemed fit to pass.
