THE SYSTEM Reducing noise from wastewater and drainage systems in the home is not only about environmental quality but about quality of life. Huliot’s Ultra Silent™ and Ultra Silent Plus™ present systems that are so effective and affordable it doesn’t make sense to install anything else in a new construction project. Huliot’s Ultra Silent™ is an effective non-pressure soundproof wastewater and drainage piping system made of mineral-reinforced polypropylene compound (PP-MD). Available in diameters from 32 mm to 200mm, Ultra Silent™ products comply with all mechanical and measurement requirements (EN 1451-1) and suit above and below ground installation both inside and outside the building structure. The system fittings are produced from black PP-MD compound and sealed with SBR-NR seals. All pipes have three layers to provide the highest mechanical performance. External black PP layer provides high-impact strength and excellent UV resistance. Intermediate PP-MD layer provides acoustic insulation and increases the pipe stiffness. Internal low-friction white PP layer provides the best flow performance, high resistance to chemical agents and high-definition contrast for visual monitoring. the system The Ultra Silent™ system advantages Fraunhofer IBP Test Laboratory results: Best measured acoustic insulation 19 db (A) at 4 l/s with basic clamps (EN 14366) Enhanced flow rate due to smart, progressive design and full range of fittings High temperature resistance: 95 °C long term, 98 °C short term Extreme low-temperature impact strength: -20 °C for assembly Improved fire behavior classification: D-s2-d2 (EN 13501-1) Lightweight, easy handling and installation: Push-fit, ring seal, connection method Swept branches improve the flow rate and reduce turbulence flow and accompanying airborne noise. Extra socket depth for increased connection stabilization. Best resistance to corrosive materials and longer lasting than other plastics and cast iron: durable for 100 years, according to raw material manufacturers, and more than 50 years, according to confirmed standard cycle test results . Environmentally friendly: most neutral material with the smallest carbon footprint and without risk during the material and product production process; 100% recyclable. Huliot’s Ultra Silent™ systems carry the Green Label licenses by World Green Building Council (WGBC). Negligible linear expansion in any direction and no need for special fittings. ACOUSTIC Noises from wastewater and drainage systems Every object in motion makes noise when it transmits vibrations – in the form of pressure or negative pressure waves – to the surrounding air. There are two types of noise in drainage and wastewater systems: AIRBORNE NOISE– comes from pipelines and is generated by wastewater flowing inside. In this case, a soundproof drainage and wastewater system should limit the propagation of airborne noise and keep it inside the pipes. This is achieved by using a specially formulated material (using minerals), a three-layer pipe structure, high manufacturing quality and correct installation. STRUCTURE BORNE – noise comes from pipes and fittings as well as the system of fastening to the building’s structure such as brackets and clamps. This sound comes from the noise inside these systems, which makes them vibrate (acoustic resonance). The resonance is transmitted through the pipe clamps to the building’s structure and is heard in neighboring rooms as an irritating acoustic wave. In this case, it is important to design the system of fastening pipes and fittings to the building’s structure in such a way that the acoustic resonance is reduced to the minimum. .
