What Is 12mm Hardwood Plywood?

Offering excellent stability and load-bearing properties, 12mm Plywood Hardwood Structural Grade sheets boast a focally pleasing smooth sanded surface which can be either painted or varnished to bring you closer to your ideal aesthetic.

What's more, this durable and versatile sheet material is suitable for a wide range of building applications. One of the best ways to use this sort of high-grade plywood is to use it as flooring or roofing. The sheets pack multiple layers of thin veneer wood, endowing them with a strength which is perfect for floor, wall and roof applications. The sheets also feature a hardwood face and a one-piece face veneer whilst conforming to the following standards EN636-2, EN314-2.

Colour and finish are representative only and may vary slightly as this is a natural product.


12mm Hardwood Plywood Applications

The cross-graining technique used in the manufacturing process of 12mm Hardwood Ply offers many benefits. The cross-layered timber veneered panel provides consistent strength and stability to both interior and exterior applications (such as external wall panels and claddings, as long as all edges are sealed and the sheets are treated with an appropriate preserver and sealer). If you are looking for an exterior grade plywood sheet, our Marine Plywood is the ultimate hardwood external grade in terms of strength and weatherproofing.

We recommend using Structural Hardwood Plywood in the following applications:

  • Furniture
  • Bath panelling
  • Flooring
  • Sheds
  • Packing cases
  • Storage boxes
  • Trailer linings
  • Interior vehicle building
  • General joinery

Note that if you are using the sheets for furniture making, plywood absorbs more paint than other wood products.


12 mm Plywood Key Benefits

Characterised by their excellent strength and rigidity, these Hardwood Plywood sheets offer a host of other long-lasting benefits. Let's explore some of these below:

  • Versatility – 12mm plywood can be used in many general purpose applications, such as internal and external joinery (providing it is properly sealed).
  • Strength - Thanks to the cross-graining process by which it is manufactured, it has a high strength-to-weight ratio. It also provides a high level of impact resistance.
  • Complies to EN314-2 Class 2 glue
  • Service class EN636 Class 2
  • CE marked
  • Durability - Designed to resist warping and bending
  • Appearance - Due to its appealing aesthetic appearance and smooth sanded surface, plywood can provide a sleek finish when making furniture such as doors and cabinets.


12mm Structural Hardwood Plywood Manufacturing Process

Hardwood Plywood is an engineered wood made by slicing wood into thin veneers and then heat bonding them together using a resin adhesive to form a sheet. When manufacturing plywood, each individual adjacent layer is rotated from 45-90 degrees (and laid at right angles) so the wood grain is going in different directions in each layer, which improves strength and prevents warping. This process is known as "cross graining".

The combination of these thin layers improves strength and makes the plywood sheets suitable for a wide range of construction applications.

WBP Plywood 12mm

The term "WBP Plywood" (which stands for "Weather and Boil Proof") refers to the type of glue that is used to bond the layers of wood veneer together.

This terminology has been superseded by the EN314 and EN636 classifications, which define the bonding quality of the adhesive and the standards to which the plywood will perform. All of our general-use hardwood birch plywood sheet materials (made from birch veneers) meet level 2 under these classifications, which means that they are suitable for use in humid conditions, and can be used outside if properly sealed. If it is exposed to moisture for a long duration of time, it can be prone to swelling and losing its shape.
