Construction giant Lida Group has successfully conducted extensive fire resistance testing on its innovative prefabricated composite insulated wall and roof panel system to further verify the solution provides an ideal non-combustible building material for dense multi-family social housing applications.

The state-of-the-art panel comprises two thin layers of reinforced concrete bonded to either side of a fire-proof insulating core. Whole wall, floor and roof panels are cast off-site then rapidly installed to form complete modular buildings.

Prior smaller-scale tests had indicated the composite assembly could achieve up to four hours of fire resistance rating. However, to satisfy new regulations and prove suitability for high-rise apartments, Lida subjected a near full-scale panel sample to a series of rigorous fire curve exposure assessments lasting several hours at independent accredited labs.

The panels impressively demonstrated zero flame-spread properties throughout the tests, with the reinforced concrete outer leafs preventing any heat transmission and insulating core decomposing non-combustibly with no smoke or toxic emissions produced. Importantly, the panels maintained structural integrity and did not failure even at extreme temperatures above 1,000 degrees Celsius.

Fire stopping sealant was also tested between panel joints and openings like windows to validate the integrated assembly provided a complete non-combustible barrier against fire spread. No flame penetration or hot gas migration occurred.

Lida Group will now proudly display the fire test certifications as it markets prefabricated modular apartment towers as a safe innovation meeting the latest codes for fast, high-quality construction of densified rental housing communities.

Independent engineers praised the system’s enhanced resident safety versus traditional combustible materials still used widely in development. The pioneering product is expected to see rapid adoption across the region’s flourishing affordable housing sector undergoing transformation to mass prefabrication.

Prefabrication using non-combustible sandwich panels eliminates fire risks associated with on-site building, significantly boosting construction quality and safety assurance. Lida Group’s extensive research and development has produced an industry-leading fire-resistance solution supporting the urgent national agenda to provide safe, sustainable homes for the low-income population.

As the preeminent expert in full precast solutions, Lida is at the forefront of establishing non-combustible composite panels as the new standard for residential building construction across Asia and globally. The latest fire testing is a landmark achievement substantiating prefabrication’s ability to deliver disaster-resilient multi-family social housing at scale.
