Fireproof brick remains the undisputed champion for direct flame contact and heat retention inside kilns or heavy-duty fireboxes. However, if you are building a protective hearth pad or wall shield, a cement fireproof board offers superior spatial efficiency and structural protection. Steel serves as an excellent finishing layer for radiant deflection, provided it is installed with adequate ventilation gaps over a non-combustible substrate.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">PREGUNTAS FRECUENTES<\/h2>\n\n\n\n<p><strong>1. Can I use regular concrete board instead of a dedicated fireproof board?<\/strong> No, standard concrete backer boards are not rated for extreme industrial heat and can degrade or transfer hazardous temperatures to combustible framing.<\/p>\n\n\n\n<p><strong>2. Does a steel heat shield need to be grounded?<\/strong> While not always required for heat protection, grounding steel shields in industrial settings is recommended to prevent static buildup or electrical hazards.<\/p>\n\n\n\n<p><strong>3. Can fireproof brick be placed directly on a wooden subfloor?<\/strong> No, fireproof brick conducts heat over time. It must be installed over a non-combustible hearth pad, often constructed with a cement fireproof board and an air gap.<\/p>","protected":false},"excerpt":{"rendered":"<p>When constructing industrial high-heat zones, fireproof brick offers the highest thermal mass and temperature resistance for direct flame contact.
