Our proprietary fire retardant, Thermex-FR, is formulated to be ignition-resistant and is the only pressure impregnated fire-retardant to successfully pass a 10-year outdoor weathering test. The very nature of our ability to prevent the spread of flame and smoke, and extend weathering, also means choosing the correct stain, paint, or coating for proper compatibility.
