Assumption and Key

NCC 2019 prescribes different methods to determine Total R-value Calculations for Volume 1 and Volume 2. The systems noted on this page are Total R-values for the building element as required by the Energy Provisions of the National Construction Code, calculated in accordance with AS/NZS 4859.2 2018 & NZS 4214. Kingspan Kooltherm® products are manufactured, tested and packaged in conformance with AS/NZS 4859.1:2018

FM Certification


The Factory Mutual Approval standard for soffit lining boards is Class Number 4880:2015 (Approval Standard for Class 1 Fire Rating of Building Panels or Interior Finish Materials). Kingspan Kooltherm® K10 G2 Soffit Board (thicknesses up to, and including, 120 mm) produced at Kingspan Insulation’s Somerton manufacturing facility is certified as achieving Class 1 Fire Rating to Factory Mutual Class Number 4880.

For further details please contact the Kingspan Insulation Technical Service Department or alternatively search for Kingspan Insulation on www.approvalguide.com.

This approval is valid for ceiling / soffit insulation only, with non–combustible walls with no height restriction. This approval is valid for any fixing specification. However, for mechanical reasons, the fixing specification and the taping specification must still be followed.
