For some of today’s high-efficiency stoves, along with older stoves and stoves that do not use heat shields, the hearth pad may be required to provide thermal protection as well as ember protection. If this is the case with your stove, then the Type 2 hearth pad is the correct hearth pad for your application. Fully non-combustible with an R-value of 2.24 or 1.592, an American Panel hearth pad will block the heat from passing through to the subfloor. It provides protection well above the minimum requirements for Type 2 hearth pads (minimum requirement of R-value=1.0).
