Grooved acoustic panels machined from the rPET Panel.
rPET Groove is CNC-machined from the rPET Panel, a rigid acoustic felt made from 100 % recycled PET bottles. The visible groove patterns give walls and ceilings depth and texture while the felt absorbs sound.
Re-Sound is a Stretch Group brand. We manufacture in our own plants in Beveren-Waas (Belgium) and Częstochowa (Poland).
rPET Groove brings texture to offices, meeting rooms, lobbies, restaurants and reception areas while reducing reverberation. The grooves are cut into the rPET Panel, so material, colours, processing and reaction to fire are those of the panel.
Every rPET Groove panel starts as an rPET Panel: rigid felt from recycled PET bottles, worked like a wood-based board. The groove pattern is milled into it.
100 % recycled PET felt, about 200 kg/m³, in a Standard or a fire-retardant (FR) version.
The pattern is milled into the felt: four patterns, see below.
Ten stock colours from one panel; any other colour to order from a RAL or NCS reference.
rPET Panel: formats, technical data and the full absorption table
The colour range is that of the rPET Panel: ten stock colours, numbered 01–10, and any other colour made to order. The product photos above show earlier colourways; specify from the numbered swatches.
Choose a stock colour
Stock colours 01–10 are always available, from one panel. Any other colour is made to order: send us a RAL or NCS reference or a physical sample. Minimum quantities for made-to-order colours on request.
Made from recycled fibres, so slight shade differences between batches are normal. Order the panels for one surface together and mount them the same way round. The swatches are photographs: ask for physical samples before you specify.
Four distinctive groove patterns to match any architectural vision. From clean parallel lines to dynamic chevrons, each pattern is precision-cut using CNC technology for perfect consistency.
Noise reduction coefficient (NRC) per panel thickness, from our product data. The felt behaves as described for the rPET Panel: the mounting and the cavity behind the panel decide how much is absorbed.
PET felt is a porous absorber: sound enters the open fibre structure and is turned into heat. How much a panel absorbs depends on its thickness and, above all, on how it is mounted. Fixed straight to the wall it treats mainly mid and high frequencies; with an air cavity or mineral wool behind it, absorption rises sharply and reaches lower frequencies.
Tested according to ISO 354 & ASTM C423 Absorption table of the rPET Panel material (12 mm, per mounting)
Reaction to fire to EN 13501-1 depends on the colour: white, grey and black reach B-s1,d0, all other colours B-s2,d0, in both the Standard and the FR version.

Waiting rooms, consultation rooms, corridors
Yes. The rPET panels carry an OEKO-TEX® Standard 100 certificate, available on request. The panel is 100 % recycled PET felt: one material, recyclable at end of life.
Under EN 13501-1 the class depends on the colour: rPET Groove is classified B-s1,d0 / B-s2,d0, like the rPET Panel it is machined from. Classification reports on request.
Yes. rPET Groove is machined from the rPET Panel and is worked the same way: cut with a saw or an angle grinder with a metal-cutting blade, CNC-milled, drilled and screwed without splitting, painted with water- or solvent-based paints.
Ten stock colours (01–10) are always available, from one panel. Any other colour is made to order from a RAL or NCS reference or a physical sample; minimum quantities on request. The range is the same for rPET Panel, rPET Groove and rPET Flex Groove.
About 3–4 working weeks, as for the rPET Panel. The minimum order is one panel, prices are on request and delivery is EXW Częstochowa, Poland.
