Non-structural plywood, also sometimes called interior plywood, is a versatile sheet material made from thin layers of wood glued together. Our plywood uses a B Bond Glue, making it less waterproof than structural plywood (thus the moniker Interior Plywood). Unlike structural plywood, it's not meant for supporting heavy weights or bearing loads. In addition to this most Non-Structural plywood is finished to a smoother surface making it easier to seal or paint.

Non-structural plywood falls under the category of interior plywood. It is not intended to bear heavy weight or provide structural support for a building. It plays a vital role in a building's aesthetics and functionality. But the main support comes from structural components like beams and walls made with structural plywood or other suitable materials.

No, Non-structural plywood is not the best choice for flooring because it's not designed for heavy foot traffic and can be damaged by moisture. It can bend or delaminate (layers separating) over time. For floors we recommend using structural plywood with a higher strength rating. As a buffer layer in plank on ply timber flooring however it is a perfect choice.

With a B Bond glue our Non-structural plywood is semi waterproof. While it can handle some occasional humidity or water it's not designed for prolonged exposure to moisture. The glue used in its construction can weaken over time when exposed to constant moisture

There isn't a standard classification of 3 specific non-structural systems. However, since non-structural elements are finishing touches, here are 3 categories they often fall under:

  1. Interior partitions: Walls, doors, and non-load-bearing room dividers.
  2. Flooring systems: This includes subflooring (the base layer under your final flooring) and underlayment (a thin layer placed on top of subflooring).
  3. Ceilings and finishes: Cabinetry, window and door trim, and decorative mouldings.

Non-structural materials are those that don't primarily support weight in a building. Examples include:

  • Doors
  • Ceilings
  • Furniture
  • Wall panelling
  • Shelving (non-load bearing)
  • Cabinet sets (frames, not shelves)
  • Interior trim (baseboards, crown moulding)
