GenStone is not fire rated. Ask about our Class A system if your installation requires it. Rule of thumb for heat sources: if you can hold your hand on the surface where you plan to install GenStone for 10 seconds while the heat source is running, GenStone is OK to install on that surface. If not, GenStone is not recommended for that area. It is the owner’s sole responsibility to ensure panels and accessories will not come in contact with flames or embers.
