(4 min read) The Importance of EN 1365-1:2012 for Load-bearing Wall Fire Resistance Testing for SIPs On 10 th April 2024, Hemsec SIPs panels achieved FR30 (30 minutes fire resistance test) & FR60 (60 minutes fire resistance test) in new, more stringent, fire resistance tests to BS EN 1365-1:2012 for residential applications. The test were carried out at Efectis UK and will enable customers to achieve improved fire-resistant performance with Hemsec SIPs. Hemsec upgraded the existing fire resistance test from BS 476 pt21:1987, FR60, to meet market demands moving towards the more stringent test BS EN 1365-1:2012. SIP panel FR30 Fire Resistance test was also added to our product certification using standard 12mm gypsum plasterboard. By updating the new FR60 to more stringent standards and adding FR30 for residential builds, Hemsec SIPs can offer better design flexibility for fire-resistant performance. What is Fire Resistance in building materials? Fire resistance is the ability of a material to withstand the effects of fire, or to resist ignition and burning. This characteristic is crucial as it determines how long structural elements and components within a building can function during a fire, providing critical time for evacuation and reducing the damage to the property. The ability of a building structure to withstand fire, at least long enough for safe evacuation and effective intervention, can mean the difference between a minor incident and a catastrophic loss. In construction and building safety, fire-resistant materials are both a regulatory requirement and a fundamental component of modern design, construction and safety planning. While no practical building material is truly fireproof, well-constructed houses and buildings can help prevent tragedies by using materials, systems and build up’s that offer fire-resistant performance. What are Fire Resistance Ratings and Standards in construction? The goal is to construct a building that slows down the spread of fire, allowing occupants to escape and giving emergency responders time to arrive. This is why materials are rated in respect of how long it would take fire to affect their structural abilities.  To ensure building materials meet necessary safety standards, they are subjected to fire resistance tests which assess performance under controlled conditions. By understanding fire ratings and fire performance, architects, builders and SIPs installers can make informed choices about the materials they use, significantly enhancing the safety of the buildings they design and construct.
