Performance

Sym-Wall^® is a robust, high performance, eco-friendly building module designed to replace traditional dry-wall (plasterboard & stud) and block-work for internal partition and party wall applications.

The panel is currently applied as a non-load bearing element for walls and as a structural cavity-reinforced plank for mezzanine and party floors. The company plans to certify the panel for structural applications in 2016.

The performance of the Sym-Wall^® variants is summarized as follows:
