Best Double-Sided Brick Fireplace Supplies for Repairs and Heat Control
For a double-sided brick fireplace repair, start by matching replacement fire bricks to the appliance’s required dimensions and material. The products below are replacement bricks—not complete fireplaces or kits for building a two-sided fireplace. Rutland’s six-pack is best for buyers prioritizing stated heat-rating information; dndsim’s 12-pack may suit larger repairs; and the WINTACK cover is intended to reduce drafts from an unused brick fireplace.
| Product | Best suited for | Key detail |
|---|---|---|
| Rutland Fire Bricks | Buyers seeking a stated temperature rating | Six bricks; listed at 2700°F |
| dndsim Fire Bricks | Larger replacement jobs | Twelve bricks; listed at 2200°F |
| YANRUIPRO Fire Bricks | Insulating mullite replacement bricks | Six bricks |
| Protalwell Vermiculite Fire Bricks | Buyers considering vermiculite material | Six bricks; listed at 2200°F |
| WINTACK Fireplace Cover | Draft control when a fireplace is not in use | Designed for brick and stone fireplaces |
Rutland Fire Bricks
These six tan fire bricks measure 9 by 4.5 by 1.25 inches and are described for residential wood stoves, fireplaces, and pizza ovens. The manufacturer lists a 2700°F heat rating and says the bricks are properly cured, non-brittle, and made to consistent dimensions with minimal color variation.
Best for: Buyers who want a six-brick replacement pack with a stated high-temperature rating and specific information about curing and sizing. The listed dimensions make them easier to compare with existing bricks in a fireplace firebox.
Limitation: The six-pack may not cover a large repair. Confirm the existing brick size and the fireplace manufacturer’s replacement requirements before ordering.
dndsim 12-Piece Fire Bricks
This set includes 12 bricks measuring 9 by 4.5 by 1.25 inches. The product description identifies them for wood-stove fireplaces and states that they are designed to withstand temperatures up to 2200°F. Their larger quantity may be useful when multiple firebox bricks need replacement.
Best for: Buyers who have counted several damaged bricks and want a 12-piece set in the listed common dimensions. It is a practical quantity to compare against a full repair list before purchasing.
Limitation: The stated temperature rating is lower than Rutland’s listed rating. Check the appliance’s specifications and do not assume that a shared size means the bricks are suitable for every fireplace.
YANRUIPRO Mullite Fire Bricks
YANRUIPRO offers six mullite fire bricks in the 9-by-4.5-by-1.25-inch size. The listing describes them as suitable for fireplaces and wood stoves, with insulating properties intended to retain heat and reduce heat loss through the chimney. It also describes the bricks as durable under prolonged high-temperature exposure.
Best for: Buyers looking for a six-brick mullite option and who want an insulating material identified in the product description. The stated dimensions make this set straightforward to compare with existing firebox lining.
Limitation: The supplied product details do not specify a numerical temperature rating. Verify the required rating for the fireplace rather than relying on a general high-temperature description.
Protalwell Vermiculite Fire Bricks
This six-pack uses vermiculite and measures 9 by 4.5 by 1.25 inches per brick. The listing states that the bricks can withstand 2200°F and highlights thermal insulation. It also describes them as higher-strength than clay bricks and says they are not as likely to peel after burning.
Best for: Buyers comparing vermiculite fire bricks with other materials and needing the listed common dimensions. It provides a clearly stated temperature rating for comparison with an appliance’s requirements.
Limitation: The listing mentions compatibility with some stove replacement-part sizes, but that does not establish fit for every fireplace. Check your unit’s manual and measure the existing bricks before choosing.
WINTACK Brick Fireplace Cover
This 39-by-32-inch indoor cover is designed for brick and stone fireplaces without steel or iron frames. It attaches with hook-and-loop fasteners, with adhesive-backed loops included for the fireplace surface. The listing says the cover can help reduce heat loss through the flue in winter and limit unwanted airflow during summer.
Best for: People seeking draft control for a fireplace that is not in use, rather than replacement firebox lining. Its stated brick-and-stone installation method may suit fireplaces without a metal frame.
Limitation: This is a cover, not a fire-resistant repair brick or a component for use while a fire is burning. Measure the opening and follow the product instructions before installation.
Buying Guide: Choosing Supplies for a Double-Sided Brick Fireplace
Are you repairing the firebox or building a fireplace?
The products here are replacement fire bricks and a fireplace cover. They are not a complete double-sided fireplace, structural masonry system, or construction plan. A two-sided fireplace has separate design and installation requirements. For construction or major masonry work, consult a qualified fireplace professional and applicable local codes.
How do you check fire-brick fit?
Measure the length, width, and thickness of the existing brick, and compare those measurements with the replacement listing. The products above are generally listed at 9 by 4.5 by 1.25 inches, but matching dimensions alone do not guarantee suitability. Follow the appliance manual for approved material and replacement guidance.
Which material and heat rating should you compare?
Review the listed material and temperature information for each product. Rutland lists a 2700°F rating; dndsim and Protalwell vermiculite list 2200°F. YANRUIPRO describes mullite but does not provide a numerical rating in the supplied details. Use the fireplace manufacturer’s required specifications as the deciding factor.
How many bricks should you buy?
Count the damaged bricks and consider whether the repair requires replacing only individual pieces or a larger section. The listed options include six- and 12-brick packs. Avoid estimating from the fireplace’s overall width alone; fireboxes can have different layouts and brick sizes.
Frequently Asked Questions
Can these products create a double-sided brick fireplace?
No. The listed bricks are replacement materials, and the cover is for draft control. None is a complete fireplace or a construction kit.
Do all listed fire bricks fit every fireplace?
No. Dimensions and materials must match the fireplace or stove requirements. Check the appliance manual and measure the existing fire bricks before buying.
Can I use the WINTACK cover while a fire is burning?
The supplied product information describes it as an indoor fireplace cover for limiting drafts and heat loss. It does not identify it as a cover for use during a fire, so do not use it over an active fireplace.
Is a higher listed temperature rating automatically the best choice?
Not necessarily. Select bricks that meet the fireplace manufacturer’s material, size, and heat-rating requirements. A higher number alone does not confirm fit or approval for a specific appliance.
