The Insulating Fire Brick (IFB) is a type of soft brick made of refractory ceramic material, a blend of alumina and silica, that can withstand extremely high temperature applications and has a low thermal conductivity. This IFB is an excellent insulator and reflects heat well.

Insulating Refractory Fire Bricks are light in weight and can be easily cut by handheld hack saw or any other hand tool like chisel or drill. They are ideal for creating custom shapes and cavities.

IMPORTANT: Do not confuse this lightweight Insulating Fire Brick (IFB) with the dense Firebrick. Hard Firebricks are much heavier, harder and difficult to shape. Insulating Fire Bricks are softer, much better insulators, and easier to shape. For example a 2300F rated IFB weights only 2 lbs. The same size hard firebrick weights more than 7 lbs.

Soft Brick with Porous Structure

Great insulator and very light weight
Made of refractory ceramic material. A blend of alumina, silica and some calcium oxide
Perfect balance of low density and homogeneous porosity.
Easy to shape, cut, and carve with common wood working tools

Withstands High Temperature - Great Insulator

The IFB insulating refractory bricks are rated for high temperature uses. The light weight fire brick application is broad, mainly as insulator in industrial and hobby kilns, forges, furnaces heated by electric spiral elements or gas burners for hot face lining or outer heat insulation.

See the temperature ratings and comparison table further below for specific models.

Insulating Fire Brick Applications

Soldering Surface for Jewelry Maker: You can easily solder jewelry on this fire brick. You may drill little holes in the brick to keep your jewelry in place while soldering. The fire brick allows you to solder more quickly and efficiently because you can concentrate the heat where you want it.

PMC+ and PMC3 Metal Clay Firing: Jewelry makers can use this fire brick as a safe surface for firing metal clay with a butane torch.

Kiln for Pottery Making: This insulating firebrick is also great to build larger kilns for pottery makers. If you have a missing or defective kiln brick, you found the perfect replacement brick to fix your oven.

Build a Mini Forge: The Lynn Manufacturing Insulating Firebrick is perfect to build a mini forge for knife making. There are many tutorials online on how to use fire bricks to build a mini forge.

Insulating Fire Brick porosity comparison to Hard Fire Brick

Structural density is in direct correlation with how brittle or soft the brick is. A 2300 F rated IFB is much softer and brittle than a 3000 F IFB, but the insulation is much better on the 2300 F rated brick. The insulation value after all comes from the porosity in the material. You can see the small voids in the detail pictures. Please choose your brick according to the properties for your desired application.
