H1.2 Treatment

LSL is treated with zinc-borate in-process to meet H1.2 hazard class requirements.

LSL Description

SolidGuard LSL is a reconstituted wood product, and part of the wider family of engineered wood products (EWPs). It is manufactured from a mix of sustainably harvested aspen and maple hardwood strands blended with an isocyanate adhesive and formed through a steam injection press. This is an ideal product where spans greater than SG 8 sawn timber are required, or where the benefits of an engineered wood product is desired, without the expense of high grade LVL products.

“Zinc Borate” is added during the manufacturing process as resistance to termites and decay and the treated product is known as SolidGuard LSL. This treatment is deemed to satisfy the H1.2 hazard class requirements and SolidGuard LSL may be used in applications where H1.2 hazard class applies.
