External Grade Combi Core Plywood (Class 2)

When we talk about External Grade Combi Core Plywood, what do we mean? In construction, there are materials you can use outside (exposed to the elements), and there are those that are made solely for internal purposes.

External Grade combi plywood gets its name from the word ‘combination.’ These panels, like the classic core, replace the veneer cross-bands with thin veneers of MDF, which visibly reduces the core veneer telegraphing.

What is External Grade Combi Core Plywood?

Exterior grade combi core plywood is constructed using veneer core inner plies and particleboard or MDF cross-bands. They are aligned next to the face and the back to provide the strength and stability needed in a veneer core. However, they have the void-free surface quality typically found in MDF or PBC.

Typically, exterior grade combi plywood ought to have the following features:

  • Durability
  • Excellent resistance to twisting, warping and cracking
  • Reduced splitting when screws or nails are applied
  • WBP certified (Water and Boil Proof)
  • Can be cut easily with a hand saw or electric drill
  • High-quality in terms of the finish

The external grade combi core plywood fulfils all these requirements. 

Applications for Combi Core Plywood

The applications of Combi plywood are numerous, especially in-home usage. They can be used to make:

  • Panelling
  • Sheds
  • Floors
  • Walls
  • Roofing
  • Storage boxes

Other uses include

  • Milling processes
  • Joinery

Because the structure is formed by binding several layers of thin veneer wood together using water and boil-proof material and then compressed, it can be relied upon to stand the test of time. 

WBP, like combi core plywood, has a high-quality finish, which can be varnished or painted, depending on what you prefer.

Conclusion

With the external grade combi core plywood, construction can take on a new face that is not only aesthetically pleasing but also reliably strong. Its versatility in external use gives construction designers more to work with.
