Foam core board is an incredibly versatile material that you’ve almost certainly used at home, in school or work. It’s an ideal option for framing photographs, mounting art and a variety of other presentations, displays and hobby projects.
You can even use it for a number of construction tasks such as filling voids and providing structural support. Foam backer boards are also moisture resistant, meaning they can prevent mold and rot in areas susceptible to humidity. Foam backer boards are easy to cut with basic tools such as a utility knife or circular saw, although a power tool is recommended for thicker materials. Make sure that you’re working in a safe environment with protective gear when using power tools.
Foam board is available in a wide range of thicknesses and styles to suit various applications. The standard foam board is made with a polystyrene core and has a white or black facer. This type of insulation has an R-value of 7.0 – 8.0 per inch of thickness and is available with foil-faced versions to reflect radiant heat. It is often used as a replacement for fiberglass batt insulation.
Hard foam panels are a common addition to the exterior of houses, preventing thermal bridging. This is where heat passes through more conductive materials such as studs, which can reduce your energy efficiency and lead to increased heating and cooling costs. They are also a popular choice for insulating the basement walls of a building or placing behind drywall in the attic of an existing house.
