The complete solution for a simple and effective floor protection for freestanding wood or pellet heaters: 1) Quick and easy to assemble modular panels. 2) Panels of identical size that fit together tightly to ensure maximum protection of the floor against any embers that could fall from the heater. Once assembled, the protection measures 137 cm D x 117 cm W. 3) Provides floor protection for freestanding heaters having overall dimensions that do not exceed 76 cm wide and 71 cm deep. Powder coated panels offer superior durability and quality. 4) Each panel is insulated with Micore® 300 (13 mm) providing a R factor of 1.03. The R-value of the floor protection must be equal or greater than that required by the manufacturer of the heating appliance being installed.
