Atenua Som

What Atenua Som does

Atenua Som is a Brazilian manufacturer specializing in acoustic windows, doors, and noise-reduction enclosures, founded in 1987 and headquartered in São Paulo. The company designs and fabricates noise-reducing window and door systems, including the patented sliding window and the premium INFINITE FINI line, and operates Brazil's only frame factory with QualiLab certification from ProAcústica, the country's principal acoustics industry body. Its technical infrastructure includes an in-house acoustic testing laboratory equipped with Sound Cam acoustic holography technology, enabling measurement-based product validation rather than purely theoretical design.\n\nThe business operates a custom, quote-based pricing model serving three primary segments: residential buyers, corporate clients, and special projects in education and healthcare. Go-to-market combines a São Paulo showroom, field technical consultants who conduct on-site acoustic assessments, and digital channels including the company website and WhatsApp. The company also runs Universidade do Som, an in-house training subsidiary, and the recurring VidroSom industry seminar, both of which function as ecosystem-building activities to expand the qualified installer and specifier base for acoustic installations across Brazil.

Core offering

Atenua Som manufactures and installs custom-made thermoacoustic windows and noise-reducing doors engineered to reduce external sound transmission by 30-40 dB. The company also offers accessory screens (mosquito, blackout, solar), a line of premium products under the INFINITE FINI sub-brand, a ventilated acoustic panel, acoustic laboratory testing services, and training through Universidade do Som. All products are produced at its own QualiLab-certified factory in São Paulo and sold to residential, corporate, and educational clients across Brazil.

Product overview

Atenua Som is a manufacturer of acoustic solutions specializing in noise-reducing windows and doors (esquadrias antirruído) for residential, corporate, and specialty applications. The product portfolio centers on three core product lines: Janelas Antirruído (noise-reducing windows), Portas Antirruído (noise-reducing doors), and Telas Mosquiteiros/Blackout/Solar screens as add-on accessories. The premium sub-brand Linha INFINITE FINI offers minimalist large-format doors and windows for high-standard architectural projects. Beyond products, the company provides services including an in-house Acoustic Laboratory for testing, Universidade do Som (training school) for professional education, and specialty products like the Ventilated Panel. All products are manufactured in-house with an acoustic testing laboratory and carry the QualiLab certification—the only frame factory in Brazil with this distinction.
