Complete Integration
The structured combination of different materials — such as timber-aluminium or the PMMA-glass mix — creates complete, harmonious and rigorously certified systems.
Sound-absorbing panels
W&S Sound-Absorbing Panels
Advanced modularity, total insulation
Certified solutions in timber, steel and transparent materials
Our acoustic barriers and our sound-insulating and sound-absorbing panels are engineered to deliver the highest level of noise reduction, long-term durability and flexibility in use. Thanks to a modern construction approach based on component modularity, they are the natural answer to noise pollution across rail, road and motorway networks, combining outstanding technical performance, streamlined logistics and sensitive integration into the landscape.
The real strength of our system lies in its flexibility and in the intelligent combination of materials.
The panels are not stand-alone elements, but modular and synergic solutions designed to adapt to the specific requirements of the designer and of the surrounding environment:
Modularity and Flexibility
The lightweight modular design makes it possible to alternate the natural warmth of timber with the strength of steel or the transparency of glazed materials, ensuring a tailor-made configuration for every site and easy handling during installation.
Uncompromised Safety
Every configuration guarantees maximum acoustic insulation and absorption performance, with the certainty of installing CE-marked devices that comply with the applicable regulations.
The Configurations
Timber Configuration
The ecological solution: the perfect choice for areas of outstanding landscape value, urban furniture or contexts where minimum visual impact is required. We use only FSC and PEFC certified timber from responsibly managed forests. The natural warmth of a living material is combined with structural strength, weather resistance and architectural versatility.
Steel and Metal Configuration
The classic high-strength solution, ideal for heavy infrastructure, motorways and industrial contexts where maximum structural efficiency, slender profiles and excellent operating life are the priority.
Transparent Configuration (Glass and PMMA)
Designed to eliminate visual impact and preserve natural light and views over the landscape. Ideal for viaducts or scenic road sections, it combines the transparency of acrylic or glazed materials with high sound-insulating performance, while keeping a considered and effective design.
The advantages of modular design
Technical optimisation and sustainability
The use of standardised, modular components dramatically reduces production times, optimises stock management and simplifies site logistics. This approach allows different geometries and materials to be combined — horizontal, vertical, diagonal, chequerboard, arrow or diamond slat patterns — on unified structural frames, delivering endless architectural variants without multiplying warehouse codes.
Cutting-edge quality and treatments
The quality of our noise-reduction systems rests on rigorous technological and industrial pillars, managed directly within our plant in S. Leo (Rimini).
Certified Safety
All our panels comply with the UNI EN 14388 standard and are mandatorily CE marked. The initial type testing carried out in cooperation with Istituto Giordano guarantees full compliance with the construction products directive.
Autoclave-Treated Timber Durability
To ensure deep protection against fungi, insects and mould, our timber undergoes a vacuum-pressure autoclave impregnation process compliant with DIN 68800/3 and EN 351-1. We use non-toxic copper-based salts, free from chromium and arsenic, guaranteeing the panels for a minimum of 10 years against rot.
Water-Based and Anti-UV Finishes
Timber surfaces are protected by eco-friendly water-based impregnating agents with transparent iron oxides, acting as a shield and filter against degradation and photo-yellowing caused by UV rays on lignin.
ECOLOGICAL & GREEN Line
Timber barriers with a technological core and photocatalytic treatments
An acoustic protection system that not only cuts decibels, but actively fights air pollution and climate change, turning the barrier into a valuable ally of the environment.
Self-Cleaning Photocatalytic Coatings
We use special finishes formulated with a nanoscale titanium dioxide pigment acting as a catalyst. On contact with sunlight and oxygen, the surface breaks down organic pollutants and bad odours; under the action of rain the walls become self-cleaning, turning toxic smog gases into completely harmless salts (limestone, sodium nitrates and carbonates) measurable in parts per billion.
High-Density Sound-Absorbing Materials
The core of the panels — such as the exclusive WS1 model — houses a sound-absorbing mat protected by a dust-proof mesh and sealed by airtight EPDM gaskets, which block noise transmission and ensure stable performance and full resistance to heat, frost and corrosion.
Virtuous Carbon Balance
Choosing FSC and PEFC certified timber means dramatically reducing energy consumption during production compared with concrete, glass, steel and aluminium, actively contributing to forest growth and to the health of the planet.
The Key Standards of the Sector
Regulatory Framework and Reference Standards
Road traffic noise reducing devices are governed by a European regulatory framework that defines their acoustic performance, non-acoustic requirements and marking obligations, giving the designer full traceability of the declared performance.
UNI EN 14388
The harmonised product standard for road traffic noise reducing devices. It sets the requirements and conformity assessment procedures that make CE marking of the panels mandatory.
EN 1793
The series dedicated to acoustic performance: sound absorption (DLα), airborne sound insulation (DLR) and in-situ test methods. These are the parameters that qualify the real effectiveness of the barrier.
EN 1794
Defines the non-acoustic requirements: static and wind loads, safety in the event of impact, resistance to falling debris, fire behaviour and environmental impact of the device.
DIN 68800/3 · EN 351-1
Govern the impregnation and the penetration class of the preservative in structural timber, the basis of the ten-year rot guarantee on our timber panels.
CE Marking and CPR 305/2011
The Construction Products Regulation requires a Declaration of Performance (DoP) supported by initial type testing, carried out at notified laboratories such as Istituto Giordano.
