How Does Burnblock® Work

Burnblock® works by preventing oxygen from reaching the wood cells, a critical element for combustion. Without oxygen, fire cannot start or spread. When heat is applied, materials treated with Burnblock® form a charred surface and release water, which absorbs heat and inhibits further ignition or flame propagation.
