SECTION V:C. OUTSIDE GLAZING
Step 2) Installation of Glazing Gasket
For inside glazed applications, install the exterior gasket prior to glass installation. For
outside glazed applications, install the interior gasket prior to glass installation.
SIZE THE GASKET LENGTH BY USING THE FOLLOWING FORMULA.
D.L.O. DIM X 1.005 (D.L.O. DIM. + 1/2%)
NOTE: To install glazing gasket, start by pushing the gasket in place at the ends.
Move to the middle, then to quarter points and work the "waves" toward the ends. Do
not stretch the gasket or it will return to its original form, creating gaps at the gasket
intersection. (Gasket length=D.L.O. dim X 1.005. or D.L.O. dim + 1/2%)
