<strong>PRODUCT</strong> CONFIGURATIONS<br />
TRIPLE INSULATING GLASS<br />
The most common triple insulating glass units are constructed with three<br />
plies of glass separated by two hermetically sealed and dehydrated<br />
spaces. This construction increases the insulating value of the glass unit,<br />
thus reducing the u-value. A triple insulating glass unit is especially useful<br />
in applications where a low u-value is necessary.<br />
While it is possible to specify a 1” triple insulating unit to coincide with a 1”<br />
dual pane insulating unit, it is not always practical. A 1” triple insulating unit<br />
is constructed with 1/8” glass plies rather than 1/4” plies used in a 1” dual<br />
pane insulating unit. The reduced glass thickness increases the potential<br />
for distortion and since the 1/8” plies are not as strong as 1/4” plies, the<br />
width and height of the glass units must also be decreased. In addition, the<br />
solar performance improvement is minimal.<br />
More commonly, triple insulating glass units are constructed with three<br />
plies of 1/4” glass and two 1/2” spaces. Viracon’s triple insulating glass<br />
units are available with the same Low-E coatings offered with dual pane<br />
insulating glass and the Low-E coating is placed on the #2 surface.<br />
TRIPLE INSULATING KEY BENEFITS:<br />
+ Two spacers provide superior insulating performance<br />
+ Reduces the center of glass u-value<br />
