Product Description

Refractory Brick / Insulating Fire Brick

YF Refractory's Insulating Fire Brick (IFB) for use in applications from 2300 ºF (1260 ºC) to 3000 ºF (1650 ºC).

Each type is formulated to meet specific thermal and physical requirements, and after firing is machined to precise tolerances. Made from high purity refractory clays and other ceramic raw materials, these IFB contain carefully graded organic filler which is burned out during manufacture to give a uniform, controlled pore structure.

Standard sizes are 9" x 4.5" x 2.5" and 9" x 4.5" x 3", but custom sizes up to 24" x 9" x 3" can be produced without any cemented joints. Thicknesses up to 4 1/2", along with widths up to 12", allow a range of shapes and sizes for applications such as suspended roof modules.

In addition to standard shapes including arches, wedges, soaps and splits, fabricated bricks are also available in special cemented or machined shapes.

A large machine shop at the factory is capable of supplying accurate machined shapes of nearly any description. The unique large slab means that a finished shape will have fewer joints than shapes made from any other IFB manufacturer. IFB shapes with drilled holes, grooves, flycuts, tapers, radii cuts, skew planes, tongue and groove, notches and chord cuts are easily fabricated in any quality IFB.
