USL Insulating Fire Bricks 2500F Pack of 6 Firebricks for Internal Lining Heating Units Insulating Warming Layer for Fireplace, Steel Furnace, Wood Stove, Ceramic Oven Kiln, Blacksmith Forge

These bricks work really great I put them inside my firebox of my smoker. Helps keep heat in and use less fire wood.

Given the fragility of this item I expected at least one to arrive broken. I was pleasantly surprised! The packaging was exceptional and none were broken. They are very well made, very solid, not brittle at all and fit into my fireplace perfectly. Kudos to this company for taking such care to ensure a good product with phenomenal packaging. It’s rare that someone cares enough these days.

Bricks fit right into our wood stove. Seems to be working as hoped they would.

These fell apart within a few months.

Use them for the inside of my offset smoker firebox and they work great for helping hold temp

The package arrived in a slightly damaged box, obviously, due to mishandling by the postal service. Luckily, everything inside was intact. Today, after using our new patio with a fire pit for almost two months, I can attest for the great quality of the GIRtech USL Intermediate Duty FireBrick 2370 F. Everything is right to the expectations or even better. I would highly recommend this product to anyone!

Put these in my offset smoker by oklahoma joe and the old boy is getting better and better . Recommend anyone that is asking about them to buy them you'll be amazed .

the rest seems ok bricks ,

Hold heat well not broken when arrived easy to cut for fit .
