What are the standard grades of veneered particle board?

They are classified into Grade I (Exterior Grade) and Grade II (Interior Grade).

What is the acceptable moisture content for veneered particle boards?

The moisture content should be between 5% and 15%.

Are veneered particle boards waterproof?

No, while Exterior Grade uses moisture-resistant adhesives, the boards are not entirely waterproof and require proper edge sealing.

What types of faces are available?

They can be commercial on both sides, decorative on one side and commercial on the other, or decorative on both sides.

Practical Notes

Ensure the correct grade (Interior vs Exterior) is specified based on the humidity and exposure of the final application.

Edges of particle boards must be sealed properly to prevent moisture ingress, which is the primary cause of swelling and delamination.

Verify the adhesive type (e.g., BWP for exterior) if the board is intended for damp areas like kitchens or bathrooms.
