Technical Characteristics
The LINEA RANGE50 includes suspended ceilings and wall claddings with specific fitting systems. For wall cladding, mechanical fixing by screwing is required, adhering to DTU 36-2 and EN 14915 standards. Suspended ceilings are fitted on a T24 grid system, following DTU 58-1 and EN 13964 standards.

Acoustic Results
Acoustic absorption is measured according to ISO 354, with data calculated per ISO 11654. The LINEA 4.2.4 wall and ceiling systems achieve a weighted index of αw = 0.75 (Class C) and αw = 0.85 (Class B) respectively, with NRC values of 0.85 and 0.9 as per ASTM C423.

Finish / Reaction to Fire
The finishes include Natural, Varnish, Wax Color, and Wax Color + Varnish, all rated D-s2,d0 / B-s1,d0 / B-s2,d0 according to EN 13501-1. The rear surface features acoustic mineral wool tiles with a density of 120 kg/m³, surfaced with black fleece facing.

Panel Specifications
Panels are available in dimensions of 1880 x 600 mm and 1265 x 600 mm. The slats have a cross-section of 42 mm (face) x 20 mm (height) with a spacing of 43.71 mm and a center distance of 85.71 mm. Black rear counter-slats measure 34 x 45 mm, and the overall thickness is 55 mm. Wood species options include Pine, Oak, and Douglas Fir, with surface masses of 8.75 kg/m², 11 kg/m², and 8.6 kg/m² respectively for wall applications. The openness percentage is 51%.
