Expand-O-Gard® Vertical Expansion Joint Cover

Expand-O-Gard® expansion joints are flexible waterproof closures for vertical building walls designed to accommodate movement between building components caused by thermal, settlement, wind, flex and seismic forces.

Expand-O-Gard is a combination of a durable elastomeric bellows attached to two metal flanges, both mechanically and chemically, by a patented bifurcation process. It is available in two designs, Style WS and Style F.

Factory-fabricated transitions are available to accommodate intersections between vertical Expand-O-Gard and horizontal Expand- O-Flash® expansion joints.

Style WS - for use on masonry construction, metal buildings and panel wall systems where flanges are concealed and/or sandwiched within the wall system.

Style F - for use in joints between new and existing vertical walls, between curtain walls and glass atriums, and other vertical building walls where the flange is part of the closure design. Style F can be surface mounted.
