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. Use FireRock’s Bricking Flange in conjunction with the Solid Block Chimney to add a brick, stone, or stucco veneer above the roof. This Solid Block Chimney is required if our plans call for a Bricking Flange.
Independently tested at 3,000 PSI compressive strength, pieces may be stacked as high as local building codes allow for masonry chimneys. To increase the solid block chimney's strength even more, insert rebar and mortar into the "hurricane" holes.
- Each piece is 6″ tall
- Additional measurements: 22" (W) x 22" (L)
- No flue liner necessary
- 15″ diameter flue, largest round masonry flue in the industry, plus no flue liner necessary
- UL 127 compliant for “zero clearance” to combustibles in verticle applications
Important: Please consult local building codes for specifics regarding any masonry fireplace application.
