Zerobound® Zero Allotment Fire Rated Wall

Zerobound® is CBMA’s fire-rated boundary wall system designed for zero-lot, narrow access, and boundary construction where space, speed, and compliance matter. Rated up to FRL 90/90/90, Zerobound® gives builders a practical alternative to bulky, complicated boundary wall systems.

Using lightweight shiplap panels and a low-component system design, Zerobound® helps simplify installation on site. It removes the need for expensive fire-rated batts, complex metal channels, specialist trades, or costly installation equipment, helping builders reduce labour, materials, delays, and site coordination issues.

Zerobound® is ideal for townhouses, duplexes, multi-residential developments, infill projects, and tight boundary conditions where every millimetre counts. Its slim panel design helps maximise usable building space while still supporting compliant fire-rated construction.

The system is non-combustible, impact resistant, mould resistant, and designed for real Australian site conditions. Zerobound® can be installed by standard site trades using typical tools, making it easier to estimate, order, handle, and install without overcomplicating the build.

Backed by CodeMark certification, tested system performance, installation guidance, compliance documentation, and CBMA’s national technical support, Zerobound® gives builders a smarter way to deliver fire-rated boundary walls without compromising performance.
