Eco Building Products, Inc., California, has achieved fire test UL723/ASTM E-84 (flame spread index < 25, progression < 10.5 feet, in an extended 20 minute test time) for Eastern Spruce (SPF) and Douglas Fir treated with the company’s PIN (phosphorus, inorganic, nitrogen) Eco Red Shield TM coating.
The treated timber can thus be used for roof and floor structural elements in buildings, conform to fire safety requirements. The coating also protects against wood rot, mold and termite damage, contributing to making lumber a safe and sustainable building material. It shows very low emissions (mostly non quantifiable levels BQL) of volatile organic compounds VOCs and low formaldehyde emissions (ASTM D5116), meeting California 01350 for indoor air emissions.
