Double Glazing Components / Insulated Glass Spacers<br />
Warm Edge Excellence<br />
The insulating glass market changed forever when what is now Quanex Building<br />
Products introduced the first flexible, non-metal-based spacer technology to the<br />
insulated glass industry in 1979. The concept of reducing thermal conductivity at the<br />
edge seal for improved thermal performance was revolutionary.<br />
So much so that it inspired further innovations, including the introduction of Super<br />
Spacer®, the industry’s first structural, foam-based spacer in 1989 and, more recently,<br />
the Dura Spacer platform, which includes Duraseal® one of the first hollow, air-filled<br />
warm edge spacers on the market.<br />
What Is Warm Edge Technology?<br />
Standard double glazed units are fitted with an aluminium spacer to separate the<br />
two panes of glass. However, the conductive nature of the aluminium results in a<br />
significant loss of thermal energy. Most of the newer spacers perform better than<br />
aluminum, but still contain some metal, and this metal is highly conductive.<br />
“Warm edge” refers to the thermal conductivity of the spacer. If the spacer material is<br />
less conductive than conventional aluminium, it is called warm edge. Fitting a double<br />
glazed unit with a warm edge spacer ensures a reduced loss of thermal energy in<br />
comparison to traditional windows as well as standard IG units.<br />
What is Super Spacer?<br />
Super Spacer® is an extruded, thermoset polymer structural silicone spacer with<br />
integrally incorporated desiccants. The shape of the thermoset polymer material<br />
is set during heat curing and can’t be reshaped through reheating. Super Spacer<br />
retains its flexibility over a wide temperature range, always returns to its original cured<br />
shape and has a low compression set. The silicone formula of Super Spacer exhibits<br />
excellent resistance to ozone, sunlight, oxidation and has excellent colour stability.<br />
The No-Metal Advantage<br />
The edge of an IG unit is the most vulnerable part of the glass to heating and cooling<br />
losses, condensation and frosting. Quanex’s Super Spacer contains No-Metal and is<br />
one of the most thermally efficient IG spacers available in the market today.<br />
