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