Glue Line and Engineered Wood Families

      plywood-lvl      plywood-lvl-use

Engineered wood products are an essential component of the modern construction industry. LVL and other innovations such as CLT (Cross Laminated Timber) are opening up new possibilities for large scale wood based construction.  LSI offer a comprehensive range of glue line additive preservatives and veneer pre-treatments for protection of LVL (Laminated Veneer Lumber), plywood and composite wood products.  Glue line additives allow insect and decay resistance to be built in to engineered wood products from the inside out at the time of manufacture.

Our Brands Include:


Azotek® Preservative (NZ)

Azotek® Preservative is the latest addition to this product family and uses state of the art chemical technology to provide highly effective protection against decay fungi and insects to LVL and related products for use in H1.2 application in New Zealand.

  • LVL is an important innovation for New Zealand building offering high strength and reliable engineering properties for critical load and large span applications – and now with the security of Azotek® Preservative protection against decay and insects.
