3.3 Fire Safety Performance
Chase EPS External Wall Cladding System consists of an EPS core that is made of fire-retarded expanded
polystyrene tested in accordance with AS/NZS 1530.3.
As a combustible external wall system, Chase EPS External Wall Cladding System has not been tested for
applications that require a
Fire-Resistance Level (FRL) and may not be installed less than 900mm from an
allotment boundary.
When installed using the materials and methods prescribed in this manual the Chase EPS External Wall Cladding
System is suitable for construction for Class 1 & 10 buildings in bushfire prone areas up to Bushfire Attack Level
(BAL) 29.
The System has successfully passed testing in accordance with AS1530.8.1:2018, which is the prescribed test
standard in AS3959:2018, for a tested system with the exposure level up to Bushfire Attack Level exposure of 29
kW/m
2
(BAL 29) and complies with the performance requirements prescribed in NCC 2019 BCA Volume 2, P2.7.5
using the application methods defined in P3.10.5.
Chase EPS External Wall Cladding must not be exposed to temperatures more than 80˚C for long periods due
to the risk of softening and damage. Heat producing appliances e.g. BBQ’s & Patio Heaters, Hot Water Services,
Flues from Heating Appliances, all must be installed in accordance with manufacturers’ requirements, so the
Chase EPS External Wall Cladding System does not become heat damaged.
3.4 Thermal Performance
The Chase EPS External Wall Cladding System is an excellent insulator that achieves high Total R-values. These
may be used to satisfy NCC 2019, BCA Vol. 2 Part 3.12.1.4 wall insulation requirements, or as input to house energy
rating software to achieve an energy rating.
Chase EPS External Wall Cladding System with breathable reflective wall wrap and 10mm plasterboard lining
achieves Total R-values in accordance with AS/NZS 4859.1.
Increased thermal performance can be achieved by adding insulation between the wall studs.
