Cellumat cellular concrete: a fire barrier

The Cellumat cellular concrete of European class A1 is incombustible and produces no smoke. A real fire barrier, it does not melt or deform.

By its thermal properties, Cellumat cellular concrete makes it possible to build walls according to the principle of "monomur". This technique without insulation, which is often a source of flame spread, is safer and can limit the burning of a habitat. Seduced by these assets, the architect Jean-Michel Pupille, manager of the architecture agency Voyelles, realized the passive house LaLauragaise at Belbèze de Lauragais in cellular concrete. The owner, a beekeeper, wanted a bioclimatic passive house on the idea of a modern Lauragaise farm, with optimized energy efficiency. The walls were realized with solid Cellumat concrete blocks of 36.5 cm thick, combined with plaster on the inside for a perfect airtightness.
