Acoustic testing: Test results and data shown are based on ISO 354:1985, according to EN 20354, 1993 acoustic measurement of sound absorption in a reverberation room, ISO 11654:1997 acoustic sound absorbing for use in buildings, and ASTM-C-423-90a acoustic standard test method for sound absorption coefficients by the reverberation room method. All these tests were carried out on veneered and varnished panels, complete with acoustic patterns, with an acoustic fleece on the reverse of each panel and a 50 mm stone wool layer with a density of 46.3 Kg/m³. Measurements and calculations were carried out on a 1/3 octave band with a bandwidth of 125 - 4000 Hz


Reference for sound absorption measured: The actual degree of sound absorption (αW) and Noise Reduction Coefficient (NRC) is influenced by the distance between the panel and the building wall or ceiling as shown in the diagrams


Specifications varnish: Matt flame-retardant polyurethane acrylic UV-cured varnish, scratch resistant, dirt- and water repellent, non-toxic, free of formaldehyde and VOCs and 100% recyclable


General processing: For professional processing only, Plexwood is composed of end grain wood and wood with the grain, this means that sanding, filling, cutting, gluing and finishing differs significantly from other wood products, when applicable, follow the instructions of the products chosen, and see our general guidelines


Reference samples: Wood is a natural product, varying in composition, on this website displayed, requested and/or delivered samples are reference samples, requesting a production sample is recommended


Transport/storage: Avoid extreme swings in air humidity and temperature, at all times, allow Plexwood to acclimatize before processing, avoid exposure of unfinished Plexwood to direct sunlight, and avoid contact with penetrating fluids or substances


Colour fastness: Colour changes under the influence of sunlight are possible
