Description
Product Overview
Protalwell presents a set of six vermiculite fire bricks designed for wood stoves and fireplaces. Each brick measures 9 × 4.5 × 1.25 inches, matching the common service part 1‑00‑900450125 and FBP6E specifications. Crafted from high‑density vermiculite, the bricks withstand temperatures up to 2200°F, offering excellent thermal insulation while resisting cracking and spalling. The flat surface ensures a uniform combustion chamber, simplifying cleaning and promoting efficient fuel burn.
Usage
These fire bricks are ideal for replacing worn or damaged bricks in residential wood‑burning stoves, pellet stoves, and traditional fireplaces. Install them in the firebox, lining the walls and floor to create a stable, heat‑resistant barrier. Suitable for both new installations and retrofits, they help maintain consistent heat output and reduce wood consumption.

No adhesive is required. The precise dimensions and flat surfaces allow the bricks to sit snugly together, creating a stable firebox without additional fasteners.
How many bricks are included in the package?
Each package contains six fire bricks, providing enough material to replace a full set in most standard stove models.
Are these bricks compatible with all wood stove brands?
They match the common service part size used by many manufacturers, including Harman and US Stove models, making them a versatile replacement option.
What maintenance is required after installation?
Regularly remove ash and inspect the bricks for any signs of wear. The flat surfaces make cleaning straightforward, and the bricks retain their insulating properties over time.
