  • Characteristics
Qualirack chipboard with tongue-and-groove joints on four sides can be used for both structural and non-structural applications in dry conditions.  This board is suitable for use in service class 1 (limited temperature and relative humidity), and can only be used in biological hazard class 1 of EN Standard 335-3.

Qualirack is available as standard with a TopFinish surface and a tongue-and-groove system on four sides.
The toothed profile ensures high stability and simple installation. It is possible to nail or screw the panels blind.
The heat-treated TopFinish surface (TF) creates an extra-hard, sealed surface with greater impact resistance, which is easy to clean.
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.
Qualirack is often used as a structural construction board for floors and walls, both in traditional house-building and timber construction.
