Fire Bricks, also known as refractory bricks, are manufactured from high-quality refractory clays and minerals to withstand extremely high temperatures without cracking or deforming. They feature excellent thermal stability, low thermal conductivity, and superior heat storage capacity.
These bricks are widely used in wood-fired pizza ovens, barbecue pits, and fireplaces, where consistent heat distribution and long-lasting performance are essential. Fire Bricks help maintain stable cooking temperatures, improve fuel efficiency, and enhance the overall cooking and heating experience. Their robust structure ensures long service life even under repeated heating and cooling cycles.
