Square 3D wood panel · 250 × 250 × 30 mm · 16 modules/m²
Arch is a square 3D wood panel from the SMOOTH series. DEKOSTYL supplies and supports the product as official distribution partner.
Arch is a square 3D wall panel defined by a curved line within its footprint. The manufacturer describes the relief as symmetrical and wave-like; its softly modelled transitions place Arch within the SMOOTH design language.
Arch belongs to the SMOOTH series. The series uses softer, more flowing reliefs than the more strongly faceted EDGE series and also includes Caro Plus and Caro Minus.
“SQUARE from the FLAT series uses the same 250 × 250 mm square footprint and is the specified flat counterpart to Arch.”
Each Arch module consists of 12 mm engineered plywood and 18 mm solid wood. Available species are oak, American walnut and ash; the manufacturer lists hard-wax oil or varnish as finishing options.
SQUARE from the FLAT series uses the same 250 × 250 mm square footprint and is the specified flat counterpart to Arch. This allows relief and calm flat areas to be planned within one common grid.
The verified Arch module measures 250 × 250 × 30 mm, covers 0.0625 m² and weighs 0.95 kg. Sixteen modules are required per square metre before project-specific waste is added.
Arch is specified as a decorative 3D wall panel. No specific sound-absorption class is stated for Arch. Cleaning and maintenance should be matched to the selected hard-wax-oil or varnish finish.

“A sculptural interpretation of premium hardwood, shifting ambient light and geometrical depth.”
Arch is a square 3D wood panel from the SMOOTH series. A curved line within the 250 × 250 mm footprint creates a symmetrical, wave-like relief. The module is 30 mm deep and can be paired with flat SQUARE from the FLAT series.
Arch is produced to order. DEKOSTYL supports product selection, sampling and technical coordination.
