But, the R-value compares how well they insulate the wall or floor from heat.Īir also acts as insulation and has an R-value of about 1.00 for a 1/2 to 4-inch gap of space. In the example above, both the granite and the brick would protect from flying sparks since both are highly fire-resistant. The measure of thermal resistance is important because it helps you know how much protection the stove board will provide against the heat from the stove. They also have a density similar to drywall, making the panels easy to cut and secure in a homemade hearth pad. These materials typically have an approximate R-value of 1.00 per 1/2 inch of material, making them ideal for use in a hearth pad. Many prefabricated hearth boards use products such as mineral board or vermiculite panels as an insulating core. A standard bricklayer (4 inches) has an R-value of 0.8. For example, 1 inch of granite has an R-value of 0.05, but if you stack two slabs together so that you have 2 inches, then the combined R-value would be 0.1. R-value is dependent on the type of material and thickness of the material. In other words, how easily does the material allow heat to pass through it? The higher the R-value, the higher the degree of insulation material the stove board has. When looking for stove boards, one number you might come across is something called "R-value." R-value is a measure of a material's thermal resistance. But, it's important to check the R-value of the material. Specially rated hearth pads (ones that are tested to not exceed 100 degrees above room temperature) can be used with high-temperature stoves even at a standard thickness of 12mm. Incorporating air spaces beneath the hearth pad or using fire-rated insulating products helps to keep the overall thickness of the hearth pad down. If your stove generates temperatures higher than 212 ☏, your pad must be significantly thicker. In general, the materials used for factory-built hearth pads are 12mm thick. The different materials allow you to customize the look of your stove, but the main point is to find something flame and heat-resistant. Wallplates can also come in many materials, including sheet metal. Options include things like concrete, slate, glass, limestone, or resin. Materials: What is Stove Board Made Of?Ī wood stove hearth or a stove board is made from a variety of fire-resistant materials. However, wall protection allows you to install the stove closer to the wall or corner, freeing up more usable space in the room. The wallboards are only necessary if the walls are within a certain distance of the stove. If you are installing the stove on a combustible surface like a wood floor, you'll likely need a stove board underneath to protect the floor. Unlike a rug, these panels are rigid, fireproof, and designed to go underneath the stove or mount on the nearby walls. They are different from traditional floor rugs or hearth rugs that you might see in front of a fire. hearth pads, heat shields, or hearth extensions) are made from non-combustible material like concrete, metal, tile, or ceramic glass. Plus, stove boards can add a lovely decorative touch! What is a Stove Board or Hearth Pad? Non-heat-resistant surfaces like sheetrock, wood floors, or carpet could warp, melt, or discolor due to the high heat. At the risk of stating the obvious, wood stoves get very hot (that's kind of the point). Most house fires are preventable, and installing the right stove pad or board as the first line of defense against sparks and embers is necessary.īut stove boards are needed to protect nearby surfaces from heat damage even without sparks. If you skimp on the proper protection, you genuinely risk losing everything. Yes, we know, "Better safe than sorry." But this is especially true with wood stoves or other hearth appliances. Consider this article a crash course in stove boards and hearth protection. We'll cover what's available, how to choose the right setup, and how to install the stove boards. The downside with so many options is that knowing where to start is hard. If anything, the stove boards add to the aesthetic of the stove and make it look more grounded and complete. They also come in many colors and styles so you don't have to sacrifice style for safety. They come in several configurations so you can have the right protection in whatever installation you choose. Stove boards shield combustible floors and walls from the stove's intense heat or any escaping sparks. Most wood stoves require a protective hearth pad, but even if yours doesn't, you still might want to consider an added layer of protection. Don't risk ruining your floors or walls - or worse yet, a house fire! A hearth pad, or stove board, offers you protection and peace of mind. Whether you have 120-year-old floors or 12-day-old floors, you should protect the area in front of your wood stove hearth with a stove board (also known as hearth boards or hearth pads).
