When installing a wood burning stove, one crucial component that often goes overlooked is the backer board. This simple yet essential element plays a critical role in ensuring the safety and efficiency of your stove. In this article, we’ll dive into the technical details of wood burning stove backer boards, explaining their purpose, types, installation, and maintenance.
The Purpose of a Backer Board
A backer board, sometimes referred to as a stove board or hearth pad, is a non-combustible material placed beneath and behind your wood burning stove. Its primary purposes are:
Heat Shield: Backer boards are designed to protect combustible materials such as your floor, walls, and nearby furniture from the intense heat radiated by the stove.
Embers and Ash Protection: They also provide a barrier to catch any embers or ash that may fall from the stove, preventing potential floor or carpet damage.
Types of Backer Boards
There are several types of backer boards available, each with its own advantages and applications. The most common types include:
Cement Board: Cement backer boards, such as HardieBacker or WonderBoard, are excellent choices due to their fire resistance and durability. They are often used for floor and wall protection.
Metal Backer Board: These are made of sheet metal and offer high heat resistance. Metal backer boards are typically used for wall protection.
Glass Backer Board: Made of tempered glass, these boards are aesthetically pleasing and are generally used as a floor protector. They add a touch of elegance to your stove area.
Installation Guidelines
Proper installation of the backer board is essential for the safe operation of your wood burning stove. Here are the key installation steps:
Positioning: Place the backer board beneath the stove, extending it to the recommended distance in front and on the sides, typically specified in the stove’s manual. The backer board should also extend up the wall behind the stove.
Fastening: Secure the backer board to the floor or wall using appropriate anchors and screws. Ensure it’s level and flush with the stove’s base.
Sealing Joints: Seal any gaps between the backer board and the wall or floor with a high-temperature silicone sealant to prevent heat or embers from escaping.
Floor Protection: If the backer board is used on a combustible floor, it should be covered with a non-combustible material like tile, stone, or sheet metal to prevent any heat damage.
Maintenance and Safety
To ensure the continued safety and effectiveness of your backer board, consider these maintenance guidelines:
Regular Inspection: Periodically inspect the backer board for any signs of wear, damage, or gaps. Address any issues promptly to maintain its fire-resistant properties.
Cleanliness: Keep the area around the wood burning stove clean and free from debris or flammable materials that may pose a fire hazard.
Clearance: Maintain the specified clearances between the stove, backer board, and nearby combustibles, as outlined in your stove’s manual.
In conclusion, a wood burning stove backer board is a crucial safety feature that should not be overlooked. It protects your home from the intense heat generated by the stove and provides a barrier against embers and ash. By selecting the right type of backer board and following proper installation and maintenance guidelines, you can enjoy the warmth and comfort of your wood stove while ensuring the safety of your home.
