Most engineered wood is not fire protected, particularly glulam, due to it already having excellent resistance to fire. However, it has the same flame spread performance as all other cellulose materials. And most of those that do use alternative treatments, often have issues with product performance, toxicity, or both.
The non-toxic Zeroignition Solution is impregnated into the cellular structure of the engineered wood components, ensuring fire protection at a nano scale in the material, with negligible impact on the wood itself, proven in both short and long term strength and environmental testing.
