Certification & Testing
Reaction to Fire:
Ignitability Index: 0 as per AS/NZS: 1530.3: 1999
Spread of Flame Index: 0 as per AS/NZS: 1530.3: 1999
Heat Evolved Index: 0 as per AS/NZS: 1530.3: 1999
Smoke Developed Index: 3 as per AS/NZS: 1530.3: 1999
Group Number:
When assessed in accordance with AS 5637.1:2015 via testing to AS ISO 9705:2003 (R2016) K-PIR Roof Panel achieves the following:
Group number: 1
Smoke Growth Rate Index (SMOGRARC) (m²/S² x 1000): <100
Insurer Approvals:
K-PIR Roof Panels are tested to:
FM 4471 approval standard for class 1 roof panels under the certified name KS1000RW for thicknesses 40mm to 120mm
FM 4880 approval standard for class 1 fire rating of building panels or interior finish materials, unlimited height under the certified name KS1000 RW for thicknesses 40mm to 120mm.
Insurer approvals are large scale testing regimes that provide objective third-party testing, which is underpinned by quarterly, half-yearly and yearly factory surveillance audits (depending on the region) to verify compliance. Insurer approvals are subject to panel thickness, width, orientation, method of assembly, steel coating and manufacturing facility.
Please contact our Technical team for project specific details.
Acoustic Performance
For a sound transmission reduction, K-PIR™ Roof Panels have a weighted sound reduction index (SRI) of RW =24-26dB*. Results are based on panels with a of similar profile and core material.
(*)Please contact our Technical Team for project specific support and product specification where Rw = 26dB is required.

Cyclonic Applications
A significant part of the Australian coastline is deemed to be in cyclonic regions. As a result of this, Kingspan have carried out testing on the K-PIR Roof Panels certified under the name KS1000RW in accordance with the requirements of the NCC Specification B1.2 low-high-low performance requirements.
For further information, please contact Technical Team for project specific support and product specification of the K-PIR Roof Panels in cyclonic applications.
