  • EN 636-3 (fully exposed exterior applications)

This resilient laminated plywood is constructed from a strong, exterior-bonded birch plywood core with a polypropylene film applied to one or both faces. The covering is bonded to the core using an elastic two-part glue meeting EN 204 D4 for exterior applications.

The hard-wearing laminate coating is available in a range of colours and designs and is UV-resistant for good colour fastness (rated 6-7 according to DIN 54004). Some decors incorporate an additional lacquer coat.

In principle, any combination of the RAL Classic colours below can be applied to the surfaces.
