Channel-Ex Safterwood fire retardant pressure impregnated joist, stud, and structural sheathing products for interior application (compliant to ASTM E84 & CAN/ULC S102) have advantage over competitor fire treated products.
Product features
- Interior rated fire retardant products uses the same chemical as weather and humidity resistant exterior rated products.
- Therefore compared boron based fire rated fire retardant wood products, it is far less likely for firmly cell-bonded fire retardant chemical to leach out by rain during construction or condensation post construction.
