INSULATING GLASS UNITS

Also known as double glazing.  They are two panes of glass separated by a layer of air or argon gas.   The panels of glass are bonded together with a Super Spacer Multi Layer Vapour Barrier  and then the airspace is completely sealed with Hot Melt Butyl.


The air is hermetically sealed and acts as an insulator.  Filling the unit with Argon Gas will further improve the insulating properties.


Super Spacer’s Argon Gas Retention

Argon gas filling is an effective way to ensure a window system achieves optimal thermal efficiencies.  Argon is a  colourless, odourless, non-flammable, non-reactive, inert gas that reduces heat transfer through the insulating glass unit versus air.  It is the most popular type of insulating gas used in this application, although krypton can also be used.


At manufacture, argon is injected between the two glass panels in an insulating glass  unit.  Whether argon gas will do its job throughout the life of the window system depends on the strength of the edge seal and the ability to keep the gas inside of the IGU unit.  Super Spacer resists argon gas escape, providing the industry’s most consistent seal and the best gas retention rates of greater than 99 percent


WHAT IS AN I.G.U? WHAT ARE THE BENEFITS OF AN  I.G.U?

The benefits of using an IGU compared to single-glazed windows:

For effective noise reduction it is recommended to have one         or two panels of laminated glass.  For best results use         Vlam Hush

You also need to consider other areas where noise can               enter your home

- gaps around windows & door frames, walls and floors.

- insulation of the walls and ceilings
