WV410 WINDOW - INSTALLATION INSTRUCTIONS
Section V – Captured WV410 Vent Glazing
Step 8
Reinstall the glass stops. The glass stops are designed to be inserted into the vent material and
rotated up and out toward the edges to lock into place. Insert a 3” long temporary piece of the
glazing wedge WEB5 at the midpoint of each stop until all four (4) are in place. See Figure 3.
Step 9
Cut the horizontal and vertical lengths of the WEB5 drive-in gasket to the exterior daylight
opening of the vent plus 2% to allow for shrinkage. Insert the glazing wedge, beginning at each
end of the stops and the middle of the gasket. Continue to divide each loop in half, working out
the “waves” toward the ends of the glass stops. Do not stretch the gasket. See Figure 4.
Step 10
After all of the gaskets are in place, flip the vent over and check for squeeze out that may have
appeared. Clean off any excess with a razor blade and paper towels.
