Product Description

We are a well-known organization, engaged in manufacturing and exporting high-grade Insulating Bricks. The offered bricks are are well-known in the market for their insulating properties from electricity and temperature. Supreme grade raw-materials are procured from the renowned vendors of the industry to manufacture these bricks. Our infrastructure facility is equipped with advanced tools and machines to manufacture these bricks. Various sizes and shapes of Insulating Fire Bricks can be availed according to our clients' demands.

Features:

  • Dimensionally accurate
  • High strength

Insulating brick, refractory brick or firebrick is utilized in coating kilns, fireplaces, furnaces and fireboxes. It is made principally to endure elaborated temperature, however will additionally more often than not have a low heat conductivity for more prominent power productivity. Generally thick firebricks are utilized as a part of usages with extraordinary chemical, thermal or chemical pressures, for example, within a wood-terminated oven or a heater, which is liable to scraped area fluxing from slag or ash, from wood and elevated temperatures. Further, in order less tough conditions, for example in natural or an electric gas fired heater, more permeable blocks, usually known as "oven blocks" are a superior decision. Normally, our insulating bricks are weaker, however they are considerably lighter, less demanding to shape, and protect obviously better than thick blocks. Protecting bricks are light in weight as well as soft. They can be effectively cut by hand operated hack saw or whatever other hand instrument like etch or even bore. Their structure is made of modest air spaces like honeycomb impact.

Utilization of low weight fire block protection is wide, for the most part in hobby and industrial kilns warmed up with either gas burners, furnaces or electric spiral components, both for heat face covering or external back thermal protection.
