Moisture ResistantMoisture Resistant

All Compakboard panels offer good moisture resistance as standard, something that is an optional (and often expensive) extra for MDF and chipboard. Compakboard has also been tested successfully for resistance to timber destroying fungi.

Problem Description

Wood does not like moisture. Not only direct contact with water but also high humidity is dangerous for wood and for chipboard and MDF boards in particular. A damp environment, with relative humidity exceeding 70%, may be present in any house, e.g., in the bathroom, the kitchen or under the roof. Wood may also be exposed to high humidity during the construction phase. This may be due to adverse weather conditions, but also after plastering the walls or pouring the floors the relative humidity inside a building can reach 90% or higher. Moisture causes wood to change (linear expansion, swelling) and in the case of board material it may have a highly adverse impact on its technical characteristics (such as rigidity, bending strength). In the most critical of environments, even surface fungus may occur.


Compakboards are a Moisture Resistant panel material and it can be specified for use in the most strenuous humid domestic interior conditions where dimensional stability and etained strength are of great importance. Some examples of application would be kitchen & bathroom furniture, skirting boards, mouldings, wall cladding, shelving and flooring. Compakboards are manufactured using MDI polyurethane as a binding agent which produces a “Zero Formaldehyde” or “Formaldehyde Free” material. This special production process and other featured characteristics positions the finished product far above the common standard values.


Compakboards can be applied in service class 2 environments (not in outdoor applications) and are capable of withstanding accidental contact with water. The products are characterised by low swelling and limited linear expansion when exposed to an increased humidity level. Brief exposure to water (e.g., rain shower at a site) will not substantially affect the mechanical characteristics. Compakboards can be melaminated, laminated or coated with another surface finish without any problems. Sawing and milling is possible using standard tools.

Compakboards are used for:

House Construction
Interior Decoration
Other Possible Applications
– Roof elements – Bathroom furniture – Concrete formwork
– Flat roofs – Laminated floors – Wall constructions (possibly with tongue and groove)
– Load-bearing floors – Kitchen decoration – Packaging material
– Special fire requirements
