About this product

Grade B is the only grade we make from clean recycled pallet wood — by rule, never A1 or A2. Painted, treated and demolition timber is rejected at our gate. Ideal for poultry sheds, glasshouses and larger boilers designed for higher-ash fuel.

Made from: Clean, untreated recycled pallet wood and arb chip — B grade only, painted/treated wood rejected.

Industrial grade B is the only grade clean pallet wood is allowed to become. It is perfect for biomass boilers designed for B-grade fuel.
