SeiMax R: Multi-Directional Roof Expansion Joint System by Unison Joints

Unison Joints are proud to present SeiMax R (Si R)- the multi-directional roof expansion joint system. The Queensland-based company is the industry leader in design, manufacture and distribution of movement joints within the building and construction industry in Australia. SeiMax R comes as part of their premier range of seismic joints, designed to provide accommodation for movement caused by thermal, wind, shrinkage, creep and seismic activity.

Up close with SeiMax R
The SeiMax range mainly consists of seismic coverplate expansion joint systems for architectural floor finishes with low maintenance features (Si G), minimum visual impact (Si T), and weather/pathogenic seals (Si D). Unison Joints understand that seismic movement not only affects the floors of a structure, but roof construction as well. Thus, they specially designed Si R to be the multi-directional roof expansion joint system of the SeiMax lineup.

Si R facilitates all kinds of seismic movement from any direction. The SiR weatherproofs the gap whilst allowing for high degrees of movement. The cutting-edge design mechanism has smooth lines which integrate well with surrounding roof and wall cladding.

Not designed for trafficability, Si R uses cbar type couplings. These cbars are manufactured from an injection-moulded composite material for nil corrosion factor and longevity. The multi-directional roof expansion joint system consists of an aluminium coverplate shaped like a ridge cap, and a secondary drape-seal for resistance to water and other weathering agents. Drainage spigots are accessory items available upon request. Unison Joints also supply Si R in a roof-wall version. And the system can be integrated with vertical wall expansion joint systems. Transition details are available from Unison's engineers.
