SGF

What SGF does

SGF S.r.l. (trading as SGF Insonorizzazione industriale) is an Italian family-owned industrial soundproofing company founded in 1986 by Franco Lerda in Volvera, near Turin, and currently led by his son Stefano Lerda. The company designs, manufactures, and installs custom engineered acoustic systems — primarily acoustic enclosures (cabine acustiche), absorption-type industrial silencers for ventilation systems (silenziatori industriali), and anechoic, semi-anechoic, and measurement chambers (camere anecoiche/semi-anecoiche e di misura) — that achieve up to 60 dB(A) attenuation. Operations are vertically integrated inside a 3,000 sqm workshop organized into sheet metal processing, mechanical carpentry, and insulation departments, supported by AutoCAD 2D, Inventor 3D, Jet Cam nesting, and the Concept production management system. Internal capability spans laser sheet cutting (2x4m), CNC panel bending (3.2m), CNC punching (1.5x3m), CNC press brakes, and crane systems.

The customer base is exclusively B2B industrial — manufacturers of noisy plants and machinery (OEMs) and end-users operating such plants across paper and cardboard, metal forging and foundries, wire and cable processing, surface treatment, energy, and food/appliances manufacturing. SGF operates a turnkey, project-based sales motion: on-site phonometric analysis, noise mapping, feasibility study, design, build, installation, certification (including CE conformity and PARE noise exposure reduction plans under Italian Law 81/08 and EU Machinery Directive 2006/42/EC), and acoustic testing — performed by an in-house team described as 11–50 employees plus the three Lerda family members.

Revenue is generated through one-time project sales (custom-designed enclosures, silencers, and chambers) plus professional-services revenue from acoustic consulting, feasibility studies, and after-sales verification. The company discloses no public pricing; each engagement is quote-based and tailored to site conditions. The firm is ISO 9001:2015 certified, holds Italian Acoustic A1 and A2 qualifications, and is IMQ certified. Stefano Lerda also serves as President of CIADI-ANIMA (Confindustria), embedding the company inside Italian industrial acoustics standards-setting. The Lerda family retains 100% ownership of the registered Italian S.r.l. (share capital €60,000); no external funding rounds, subsidiaries, or M&A activity are disclosed.

Core offering

SGF designs, manufactures, and installs custom industrial soundproofing systems, including acoustic enclosures (cabine acustiche), absorption-type industrial silencers, and anechoic/semi-anechoic and measurement chambers. The company operates a turnkey process covering on-site phonometric analysis, noise mapping, feasibility studies, design, in-house fabrication, installation, CE conformity certification, and final acoustic testing for industrial manufacturers and end-users of noisy machinery.

Product overview

SGF is an industrial soundproofing company offering a portfolio of acoustic systems including soundproof cabins (Cabine acustiche), industrial silencers (Silenziatori industriali), anechoic and semi-anechoic chambers (Camere anecoiche e semi-anecoiche), and measurement chambers. These core products work together to provide comprehensive noise reduction and control solutions: soundproof cabins contain noise at the source, silencers manage ventilation noise, and anechoic/measurement chambers enable precise acoustic testing. The offering is complemented by acoustic treatment services for workplace environments, after-sales support including acoustic testing and certification, and advanced sound level measurement equipment. SGF handles the entire design, production, and installation process internally from their 3,000 sqm workshop.

Direct peers

• Plinger (R. Plinger GmbH): Austrian specialist in industrial soundproofing, anechoic chambers, and acoustic enclosures with a comparable product portfolio (cabins, silencers, measurement chambers) and similar B2B industrial customer base across Central Europe. Most directly comparable peer due to overlapping scope and German-speaking market proximity.
• Acoulite: European acoustic enclosure and silencer manufacturer serving OEMs and industrial end users with comparable cabin and ventilation silencer products, often competing for the same industrial noise compliance projects.
• Mas Acoustics: Italian industrial acoustics competitor also serving manufacturers of noisy machinery with enclosures, silencers, and acoustic treatment solutions. Direct domestic peer within Italy.
• Acustica Integral: Spanish industrial acoustics firm offering soundproof cabins, silencers, and acoustic enclosures with similar turnkey engineering and installation services, primarily serving industrial customers in Southern Europe.

Broad incumbents

• Industrial Acoustics Company (IAC): Global incumbent in industrial noise control with modular acoustic enclosures, anechoic chambers, and silencer products for OEMs and industrial operators worldwide; significant scale advantage but overlapping product scope.
• Brüel & Kjær (HBK): Global leader in acoustic measurement instrumentation and anechoic test chamber design; while much larger and focused on measurement hardware, they overlap with SGF in anechoic chamber design and sound level measurement consulting.
• Ecophon (Saint-Gobain): Major acoustic ceiling and wall panel manufacturer under Saint-Gobain, supplying industrial and commercial noise control solutions; broader portfolio but competing in workplace acoustic treatment where SGF also operates.

Emerging players

• SoundPLAN (SoundPLAN GmbH): European noise mapping and acoustic planning software provider used in industrial noise assessment and compliance; complementary to SGF's phonometric analysis and noise mapping services rather than direct competition.
• Silvent: Specialist in industrial noise and compressed-air silencers with engineered blow-nozzle and silencer products serving manufacturing; narrower scope than SGF but adjacent in industrial silencer technology.

Regional players

• CSI (Comint acoustic solutions): Italian competitor focused on acoustic insulation and silencer manufacturing for industrial and HVAC applications; overlaps with SGF's silencer and HVAC noise control product lines.
