Mortar spacers are available in several sizes, some specific to the product line. These plastic mortar spacers speed up construction, assure uniform placement and help keep panels flush as well as maintain joint consistency.

Seves Glass Block Expansion Strips are made of white polyethylene foam, and inserted at the heads and jambs. The strips replace the mortar at these points to cushion the glass block and allow the panel to expand and contract freely. The Expansion Strips are available 3/8” thick x 3” widths x 16” lengths.
