SPACERs<br />
An insulating glass spacer is placed within the unit to separate the two or more plies of glass. Viracon’s insulating glass spacers<br />
are available in two colors, three materials and a variety of thicknesses. When specifying an insulating glass unit, it is necessary<br />
to specify all three; color, material and thickness.<br />
APPEARANCE<br />
Color choices include a black painted finish or a mill finish<br />
which has a silver appearance. Mill finish spacers can be<br />
seen in the majority of existing buildings as they were the<br />
standard in the glass industry for many years. The trend is<br />
moving however to black painted spacers as designers see<br />
the clean look this option provides. The black tends to blend<br />
with the gaskets and framing which minimizes the overall<br />
visual impact by leading occupants to look through the glass<br />
rather than at the framing or spacer. The color of the spacer<br />
does not affect the solar performance of the insulating glass.<br />
THICKNESS<br />
The thickness of the spacer will determine the distance,<br />
or space, between the two glass plies in an insulating unit.<br />
Viracon’s typical 1” insulating units are constructed using<br />
a 1/2” (13.2 mm) nominal thickness spacer, however a wide<br />
variety of alternate thickness spacers is available. Even a<br />
minimal change in the thickness of the spacer can affect<br />
solar performance so it is important to include the thickness<br />
in a specification.<br />
