Managing Connections: Dynamic Floor and Wall Joints (movement mayhem)

Posted on by Tremco

Some of the most demanding connections within a building design are joints within floors and walls that must allow for building movement. These connections must be able to withstand maximum wind loads and building movement from thermal, seismic and moisture content changes, deflection, and creep.

“Drift joints” are designed into projects to accommodate movement over time. 

Other assemblies within the building envelope where spanning of voids is commonplace may include roof to wall, floor deflection joints and expansion and control joints, where a degree of movement is anticipated.

These gaps are too large to seal with a sealant and a peel-and-stick membrane won’t withstand the movement. In addition, the joints and the materials that are used to seal them must be able to support the same air pressures as the air barrier material without rupture or displacement.

Tremco's patented Proglaze® ETA ensures a continuous, compatible seal while providing a durable connection designed to absorb dynamic movement and wind-loading stresses without it pulling apart.

The Silicone Rubber Extrusion is so flexible it can span and seal across irregular or unsupported joints while meeting the most stringent performance requirements. 

The unique stacking joints within the floor to wall assemblies at the Rush University Medical Center in Chicago put connection performance to the test.  

Choosing the right product for the application is critical in any application, but the demands of this application made Proglaze ETA vital to the long-term success of this aggressive building design.
