From Bottles to Silence
Transform your space with rPET - Groove acoustic panels. Made from recycled plastic bottles, these elegant grooved panels combine contemporary design with exceptional sound absorption. Efficiency meets elegance.
Re-Sound is a Stretch Group brand. We manufacture in our own plants in Beveren-Waas (Belgium) and Częstochowa (Poland).
rPET - Groove panels bring a contemporary touch to any space while reducing noise disturbances. The visible slat design creates visual depth and texture, perfect for modern offices, meeting rooms, lobbies, restaurants, and reception areas.
Each rPET - Groove panel gives new life to approximately 60 recycled plastic bottles. Our manufacturing process transforms post-consumer PET waste into high-performance acoustic felt, creating a truly circular product.
Post-consumer plastic bottles are collected and sorted
Bottles are cleaned, shredded, and melted into PET fibers
Fibers are compressed into dense acoustic felt sheets
CNC precision cutting creates the signature groove patterns
From neutral tones to bold accents, our curated color palette fits seamlessly into any interior design concept. All colors are achieved through dope-dyeing, ensuring excellent color fastness and UV resistance.
Colors stay vibrant even in sunlit spaces
Vacuum or wipe with damp cloth
Batch-to-batch color consistency guaranteed
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.
