ONDA is a sculpted panel made of HDF which starts out with a thickness of 18 mm, while the final thickness depends on the depth of the sculpting and varies from area to area. ONDA is ready to be lacquered.ONDA and BiONDA panels are all in size 3050x1220 mm to clad any wall and they all have designs studied to guarantee the continuity of the elements when two panels are matched on either the long or the short side.Some of the sculpting procedures developed for ONDA are unsuitable for BiONDA. Sculptings which run vertically can also be supplied in the horizontal (H) version.The ONDA boards, being machined on one side only, show flatness variations. The panels, therefore, have to be fixed mechanically or bonded on a further stabilizing core.
