Durelis is an MUF-glued, versatile, moisture-resistant chipboard suitable for load-bearing applications. As an excellent alternative to traditional OSB/3 boards, Durelis is suitable for applications in environments with a high relative humidity level.



Durelis’ unique composition ensures that swelling and linear expansion remain limited.
These construction boards can be used in service class 2 (limited temperature and relative humidity) and can only be used in biological hazard classes 1 and 2 of EN Standard 335-3.

Durelis is available with a sanded surface or a TopFinish® surface.
The heat-treated TopFinish surface (TF) creates an extra-hard, sealed surface with greater impact resistance, which is easy to clean. The increased concentration of natural paraffin in the surface increases its moisture resistance. Our boards with a TopFinish surface also score highly for airtightness. These advantages mean that boards with a TopFinish surface are particularly suitable for building applications.
A fine, sanded surface (SA) is recommended if the Durelis board is going to receive an additional finish of melamine, finishing foil, lacquer, veneer or laminate, as is often the case in interior applications.

Durelis is available as standard with straight edges, but can also be finished with a tongue-and-groove system (TG). The toothed profile ensures high stability and simple installation. The system makes it possible to nail or screw the panels blind.

Durelis can be used in both traditional housing construction and timber construction as a structural construction board for floors, roofs or walls. This board is also useful for non-load bearing applications, such as interior fittings in zones with a high relative humidity.

Furthermore, it works perfectly as single use or multi use concrete formwork.
