High-rise construction presents unique fire safety challenges that demand wall materials with proven, third-party tested performance. 100mm ALC wall panels have emerged as a game-changing solution, consistently delivering over 3 hours of fire resistance when tested to ASTM E119 and EN 1364-1 standards—performance that was previously only achievable with much thicker, heavier masonry walls.

The secret behind this exceptional fire performance lies in ALC’s unique porous aerated concrete structure. Millions of tiny, evenly distributed air bubbles trapped in the high-pressure cured concrete act as natural thermal barriers, drastically slowing heat transfer through the panel. Unlike dense concrete that conducts heat rapidly, the low thermal conductivity of ALC means that even when one side of the wall is exposed to 1000°C flame, the unexposed side temperature rises very slowly, preventing spontaneous ignition of materials in adjacent rooms.

For high-rise projects, this 100mm thickness with 3+ hour fire rating offers massive practical benefits. ALC panels weigh only 500-800kg/m³, roughly one-fifth the weight of traditional concrete or clay brick walls. This significantly reduces the total dead load on the high-rise structure, allowing engineers to design lighter foundations and reduce overall construction costs. At the same time, the 3-hour fire rating fully satisfies the most stringent international building codes for high-rise compartment walls, elevator shaft enclosures and stairwell separations, ensuring that vertical fire spread is completely contained for the full duration of emergency evacuation and firefighting operations.
