#40 Two-Piece Expansion Joint
Two-piece expansion control joint
#40 Expansion Joint is a two-piece, slip joint that finishes butt ends of adjacent panels in wide or tall walls and ceilings to allow for multi-directional movement.
Quick Actions:
Panels are attached to parallel studs through the expansion joint flanges, enabling the finished surface to expand or contract naturally without cracking. #40 is ideal for joining dissimilar wall types such as wood framing to CMU and at construction joints. If installed horizontally, assure female portion is on top.
The adjustable expansion opening, or reveal, is 1/4" to 5/8". Additional weather shields should be installed behind the joint to enhance the weather resistance of this system. Backer-rod and elastic sealant is often installed to assure water resistance.
The #40 Expansion Joint is also available in zinc for increased corrosion resistance.
