Installation Guide

• Line up enough glass blocks to complete the next row.

Apply two beads of sealant (Illus. I) and install these blocks

sealant side down on horizontal spacer (Illus. J). Install

vertical spacers and align the row with previous row.

•

Repeat these same procedures for all rows, except the top row.

• Before installing these blocks apply a

” bead of sealant

horizontally along the top inside leg of channel where the

glass block face butts.

• Install the glass blocks then slide the vertical spacers in from

the front of the glass block joints. The last spacer may need

to be tapped in with a rubber mallet (Illus. K).

SEALANT

• Place the horizontal spacer on top of the ﬁrst row of glass

blocks (Illus. I). Remove any excess sealant. Adjust size of

beads of sealant to prevent squeeze out (keep joint areas

clean). If it’s necessary to have a joint in the end of the

horizontal spacer to extend it, cut the spacers so that the

joint is under a vertical spacer. Stagger these horizontal

joints from end to end on each proceeding row of

glass blocks.
