Fire Resistance

Concrete block simply does not burn. Masonry walls have been used for centuries to limit the chances of devastating building fires and to contain fires from spreading.


Concrete masonry does not burn, melt, or warp, and is the ideal material for fire-resistant applications.

A firewall built with concrete masonry is less expensive to construct and safer during a fire than a composite wood and drywall firebreak in multi-story residential applications.

Concrete masonry fire walls and fire separation walls may be designed to maintain structural integrity for over four hours of exposure. Concrete masonry is also used to protect the structural integrity of steel building elements from fire.

Concrete masonry is widely specified for fire walls and fire separation walls because these elements are noncombustible, provide durable fire resistance and are economical to construct.

A Concrete Masonry Check-off program will support the growth of the industry by educating designers, contractors, and installers as well as regulators, students, and owners about how to best take advantage of what concrete masonry has to offer. It will provide for significant and sustained research and development for existing and evolving concrete masonry products and systems, and it will enable the industry to better promote the product's benefits. The check-off program will leverage the combined strength of the entire concrete masonry industry while supplying the necessary funding to support industry initiatives and coordinate promotion at the local, state, regional and national levels.
