FireRock Systems Solid Block Chimney

FireRock’s patented one-piece interlocking components make it easy to add an all-masonry chimney to your fireplace. Approved for indoor and outdoor fireplaces, these nesting blocks may be stacked as high as building code allows.

This Solid Block Chimney is required if our plans call for a Bricking Flange.
