Q:Ive built a permanent cinder block fire pit, filled it with cement. Will these protect the blocks from cracking?
by|Dec 12, 2019

Answer This Question

A:  No, while these fire bricks will withstand very high temperatures, they so not insulate and so will not protect the blocks from the heat.

    A:  Yes, it did for me, I used cinder block filled with concrete also, with these firebrick lining inside hearth. Works well for over a year now.

                  A:  Yes, they'll work fine. I used concrete "stepping stones" for the floor of my fire pit and arranged the fire brick on top of them to the size of the grate. Was less expensive than doing the whole floor in fire brick. Been a couple of years now and no problems.

                    A:  Can't tell you for sure, because I have never used them in the exact project you describe. I have, however, used them in a wood stove inside the house, and they work great!

                    by|May 9, 2021

                    A:  Yes, most certainly. I have installed them in my in house fireplace. That more than two seasons ago. I also have a 'firebox' with legs for an outdoor 'traveling' fireplace. My in house fireplace gets much hotter than the traveling one, at least mine does. If you are thinking of an outdoor fire pit, I would put some sand down and then the Fire Brick. They will last years.

                        Q:Will these brick work well under a 40" diameter metal fire ring? How many will I need?

                        A:  Came packaged well and none were broken. Installed easily.

                        by|Oct 29, 2019

                        A:  I think the brick would work. Assuming you going to make a brick bed in a circle of 40” diameter, the area of that circle is approximately 1245 sq inches (3.1416 x 20squared) and each brick has an area of 40.5 (4.5x9) sq inches. So divide 40.5 into 1256 and you will get 31 bricks. You will need a few more bricks as you will have to cut some bricks to properly fit the round edges.

                              A:  While these fire bricks are rated to be exposed to temperatures up to 2700-degrees F, they do not insulate and so will not keep the heat away from the wood.
