Beyond structural performance, fire, acoustics and thermal “are perhaps the key elements of wall system performance and specification.
Case study
Application: Non-Combustible External Walls and Common walls requiring an FRL Performance: Fire Resistance, Sound Transmission Resistance and Thermal Resistance
Application Overview
Whether on a boundary or in a facade of high-rise apartments, external walls require non-combustible insulation to reduce fire risk, while delivering peaceful acoustics and thermal performance for occupant comfort.
Similarly, many internal walls in commercial and multi-residential buildings require enhanced acoustic and fire separation, while some also require a thermal rating.

Non-Combustible External Walls
The use of non-combustible components in high-rise external facades is critical in preventing the vertical spread of fire, this includes insulation. If combustible insulation is used, fire could potentially spread within a facade cavity unnoticed.
Additionally, with increasing construction near transport corridors, external wall acoustic performance is becoming standard in project specifications. Add this to NZBC thermal performance requirements and increased stringency in fire performance, designers, engineers and builders are looking for standardised solutions for fire, acoustics and thermal insulation.
