Test Result Summary:
  Wood

Variances depending on wood species.

Water absorption of up to 43%.

Swelling of up to 5% in thickness and width.
MDF

Variances depending on manufacturer and quality of MDF.

Huge water absorption (90%).

Swelling of up to 80% in thickness.

Delaminating of exterior foil.

Turn green after products have dried.
High Definition Polymer System (HDPS)

- No major dimensional variances as shown in the photographic evidence.

- Excellent moister resistance; molding have to be properly installed and ends need to be covered with adhesive.

- Water absorption is less than 1% in weight
