External panels are made of knotted spruce and may be supplied untreated or surface-treated. The surface-treated external panel is painted twice, once with a primer and once with an intermediate coat in any colour. We offer colour systems such as alkyd, acrylate or whitewash.
For economical and time-saving reasons, surface-treated external panels are very advantageous. The external panels are ready for assembly, however, a final top coat should be applied within 12 months. Finger-jointed and coated external panels up to 7.5 metres is one of our specialties.
