Argon Gas filled windows feature a double or triple glazed unit that is filled with gas between the panes of glass to increase energy efficiency and sound proofing.

Argon Gas increases the windows ability to insulate by reducing the heat transfer. Argon Gas does not conduct heat as readily as air, so it helps keep heat in during the winter and out in the summer at the same time as an advantage in decibel reduction.

WHAT DOES ARGON GAS LOOK LIKE? WILL I SEE IT IN MY WINDOWS?

No, Argon Gas is clear, colourless and odourless. Even if installed side by side, you cannot see the difference between a window filled with gas and one without.

HOW LONG WILL THE GAS STAY IN THE WINDOW?

Numerous studies show that gas typically leaks out at less than 1% per year. Over twenty years the window still has at least 80% of the gas still trapped inside it.

IS ARGON GAS DANGEROUS?

An emphatic NO! Argon Gas exists naturally in the air you breathe – it is both non toxic and inert.

WILL MY HOUSE PLANTS GROW?

Argon does not block any portion of the suns light. House plants will not be affected.

WILL ARGON GAS GIVE ME AN A-ENERGY RATED WINDOW?

Argon Gas

No. Filling the glass sealed unit with Argon Gas alone will not give you an A-energy rated window. Whilst it will improve the thermal efficiency of the window, other measures need to be taken.

Sealed units used to have aluminium spacer bars separating the two panes of glass – these were conductors of heat and cold. Now spacer bars are made of an insulating plastic composite material that becomes a barrier to heat loss. We use the Warm Edge Spacer which does exactly as it ‘says on the tin’ – keeping the edge of the sealed unit warm. At the same time, the window frame needs to be manufactured in a way that meets a standard of thermal efficiency as well as be certified with a Window Energy Rating (WER) to confirm the whole window in its entirety has been correctly produced.

IS IT ONLY FOR ENERGY SAVINGS?

Whilst energy savings are important, the real “comfort” benefit of gas filling the sealed unit is the increase in the inner glazing temperature. Raising the inner glass temperature acclimatises or substantially reduces condensation on the glass. A “warmer” surface is also more comfortable to be near.

There is also a sound proofing element.

DO ALL WINDOWS HAVE ARGON GAS?

Unfortunately not! Gas filled windows are manufactured using specialised equipment and not all manufacturers have these facilities. So when buying new windows make sure your supplier can offer the benefits of Argon Gas for that extra insulation.

Or why not leave it to Cosyhomes. We have been providing Argon Gas filled sealed units with our Warm Edge Spacer bar and A-energy rated window frames to all our customers as standard since 2010. If you want to take thermal efficiency and sound proofing even further, get in touch about upgrades you can make to your existing windows by changing glass units alone or our new Rehau 36mm and 44mm triple glazing.

Simplicity is the ultimate sophistication.
