Firebrick options for FireRock fireplacesFirebrick Colors & Sizes

Firebrick used must comply with ASTM standards C1261 and C27 and meet or exceed the requirements of local, national and international building codes regarding fireplace and chimney construction and the National Fire Protection Association NFPA-211. A compliant firebrick lining is 1 ¼” or 2 ½” thick. Although you can use either firebrick thickness to line the sides, back and floor of the firebox, FireRock recommends using the 2 ½” thick firebrick to line the floor and ¼”on sides to provide true opening size.
