Exterior Fire-X Specifications
Exterior Fire-X, yet another safe, strong, and sustainable product, is pressure-impregnated fire-retardant lumber and plywood that provides high-level tested protection against open flame for projects that are exposed to the weather or humidity (whether this exists either indoors or out).
This cutting edge product can be used in the best construction practices of exterior decks, balconies, siding, trim, mouldings, and roof shreathing. Exterior Fire-X is non-corrosive, and it can be easily painted or stained. It is put through multiple strength tests, and because of this, it passes even the most restrictive building codes.
Exterior Fire-X fire retardant treated lumber and plywood has a 25 or less flame spread when tested in accordance with ASTM E-84 “Standard Test method for Surface Burning Characteristics,” and has no increase in fire hazard classification when this test is extended from the standard duration of 10 minutes to 30 minutes.
In addition to flamespread testing, test material has been subjected to ASTM D-2898 “Standard Method of Accelerated Weathering of Fire Retardant Treated Wood for Fire Testing.”
