SPACERs<br />
MATERIAL<br />
When selecting a spacer material it is necessary to be aware of the different u-values used in the glass industry. Center of glass<br />
(COG) u-values represent the center of the glass. Center of glass values provide an effective way to directly compare glass<br />
products without bias from spacer material, framing or unit size. Edge of glass (EOG) values represent the perimeter of the glass<br />
unit affected by the spacer material. Values are weighted based on the area of the unit to provide an overall u-factor. The overall<br />
value is typically an input needed to run whole building energy calculations and determine code compliance.<br />
COG = 15.7 ft 2 (65%)<br />
EOG = 3.6 ft 2 (15%)<br />
area = 24ft 2<br />
u-factor = 0.4<br />

Aluminum, Stainless Steel and ExtremEdge<br />
are the three spacer material options<br />
available from Viracon. Although aluminum<br />
is the most specified, increasing energy<br />
requirements are escalating the demand for<br />
alternate spacer options to improve edge<br />
of glass (EOG) u-value. Spacer materials<br />
that improve the EOG u-value beyond<br />
the performance offered by aluminum are<br />
commonly grouped together under the<br />
category of warm edge spacers or warm<br />
edge technology.<br />
ALUMINUM<br />
Historically has been the most-used spacer<br />
because of its malleability and availability.<br />
FRAME = 4.7 ft 2 (20%)<br />
STAINLESS STEEL<br />
A warm edge spacer option offered by<br />
Viracon. Stainless steel is less conductive<br />
than aluminum and has one-tenth the thermal<br />
conductivity of aluminum.<br />

NEW<br />
Viracon’s newest warm edge spacer<br />
offering. The ExtremEdge spacer consists<br />
of a biopolymer in the cross section area<br />
which is encapsulated in stainless steel.<br />
This combination further reduces the edge<br />
conductivity and thus reduces heat transfer<br />
into the building.<br />
