What role does refractory cement play in chimney construction?

Refractory cement is specifically designed to withstand extremely high temperatures, which is essential in chimney construction. Its ability to resist heat makes it vital for lining flues and masonry components that come into direct contact with the combustion gases from fire. This thermal resistance helps prevent the degradation of the chimney structure and reduces the risk of chimney fires. By maintaining structural integrity under high thermal stress, refractory cement ensures safe and efficient operation of the chimney system, contributing to overall safety in the home.
