Roof to Wall
PermaSpan RW 3-Axis Expansion Joints are ideal for allowing thermal movement and condensation control between a roof system and vertical terminating wall. The Expansion Joint prevents condensation by insulating against internal building temperatures and the 3-axis movement allows for vertical motion for live loads with no loss of thermal or seismic motion. Also, the continuous cleat protects the PermaSpan RW 3-Axis Expansion Joint from wind-driven rain. This carefully engineered product ensures long-lasting quality and high performance.
