Vertical Expansion Joint Cover

Vertical Expansion Joint Cover

Features

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. Each Expand-O-Gard cover is a combination of a flexible rubber membrane, with two metal flanges, adhesively and mechanically combined to the bellows by a patented bifurcation process.

Advantages:

• Accommodates multidirectional movement
• Non-reinforced bellows for both geometric and elastomeric movement
• Designed in a variety of styles for application requirements
• Labor saving factory crafted intersections to fit most needs or custom designed for special needs

Bellows: 

• Widths: 4" - 12" (10.16 cm - 30.48 cm) Standard (Special sizes are available up to 54" [1.37 m] wide)
