It is exciting for us to share the features and benefits of this little-known product. Lock-Deck™ laminated decking is one of the best-kept secrets in the building material world; a product that was created decades ago by the Potlatch Corporation. Lock-Deck is a structurally engineered product, comprised of multiple kiln-dried lumber laminations which are bonded together with an exterior waterproof adhesive to form glue-laminated decking. Its unique construction process provides many great design options for today’s residential and commercial buildings.
Whether you are looking for large spans in a residential “car decking” application, or need partial FSC material credit for the exposed ceilings in your next LEED commercial project, Lock-Deck can help provide a solution. Engineered for strength, and with different grade and species options for the face veneers, Lock-Deck a wise choice for your next project.
This manufacturing method allows for multiple options when choosing the quality, species, and sourcing for both the inner and outer layers that will be visible on your project. One of the nice options with this product is the ability to specify the use of FSC-certified material for portions of the finished product. If your LEED commercial project requires the 5x8 double tongue and groove, you could request which laminations be FSC-sourced material, and get a partial FSC credit for your project. The options listed above make Lock-Deck laminated decking a fabulous choice when designing roofs, ceilings, mezzanines, and floors in homes, churches, or your next LEED commercial project.
