"We believe that for buildings with a storey over 18m and/or with public occupancy, BS 8414 large-scale fire safety system checks should underpin compliance for all façade systems regardless of insulation type."
Mark Harris, Kingspan Insulated Panels Building Technology Director
One route to compliance, which is underpinned by small-scale testing, involves meeting the guidance in paragraphs 12.6 to 12.9 of Approved Document B. With specific reference to Insulation Materials / Products, paragraph 12.7 states:
"In a building with a storey of 18m or more above ground level any insulation product, filler material (not including gaskets, sealants and similar), etc. used in the external wall construction should be of limited combustibility."
In addition, paragraphs 12.6, 12.8, 12.9 and Diagram 40 provide additional guidance for the surface of exernal walls and cavity barriers. In June 2017, following the tragic events at Grenfell, DCLG issued additional guidance in relation to the interpretation of paragraph 12.7. This additional information is shown on page 19 of our Building Regulation Fire Performance Requirements for Insulated Panel and Facade Systems brochure which can be downloaded here.
Non-combustilibility and limited combustibility are both determined by small, bench-scale tests where small samples of materials are testing in isolation, unlike BS 8414 which tests materials within full wall system assemblies.

Insurance industry requirements for property protection within the UK has led to the development of additional large-scale system tests for reaction to fire and fire resistance. These rigorous tests provide a good indication of how a building will behave in a fire, and the results have been backed up by independently-assessed real fire case studies involving Kingspan insulated panel systems.
