Soundproof, triple layer, push-fit system made of pipes and fittings for soil and waste discharge, at low and high temperatures, both within the building structure (application area code “B”) as well as buried in the ground (application area “BD”). Pipes have a three-layer wall structure with external and internal layers of polypropylene (PP) and a middle layer of mineral-filled polypropylene (PP-MD). Fittings are made of mineral filled Polypropylene (PP-MD). All materials are halogen and cadmium free. Joints are made with push-fit sockets and elastomer seals. Suitable for the drainage of fluids, in compliance with DIN 8078, with pH between 2 and 12 at atmospheric pressure and at maximum operating temperature between 95°C and 98°C for short periods. Suitable for the construction of ventilation, rainwater and drainage systems. Can be used at environmental temperatures no lower than -25°C. The system has a sound level Lsc,A of 15dB(A) at a flow rate of 2 l/s, measured in compliance with EN 14366 and certified by the Fraunhofer Institut Für Bauphysik of Stuttgart number P-BA 20/2019e. The test was conducted using Huliot acoustic clamps. Fire performance rating is D-s2,d2 in compliance with EN 13501-1. The Ultra Silent™ System is certified by: SKZ, DiBt – Germany, DTI- Denmark, AENOR – Spain, WaterMark Australia and SII – Israel. In compliance with HR 3.43, EN 14759, UNE EN 1451-1, IS 958 “Plastics piping system for soil and waste discharge (low and high temperature) within the building structure”.

• Excellent acoustic performance: 15dB(A) at a flow rate of 2 l/s, in compliance with EN 14366 using Huliot clamps
• High impact resistance even at low temperature -25°C
• Excellent resistance to high temperatures: 95°C continuous, 98°C discontinuous
• High chemical resistance
• Increased socket depth for stable assembly
• Branches with swept angle and optimized design for smoother and increased flow
• Wide range of diameters: DN 32mm to DN 200mm
• High UV resistance due to black color of external layer
• Recyclability: Ultra Silent™ products have the Green Label mark for environmentally-friendly products
• All materials comply with RoHS directive and are Halogen and Cadmium free
• 10-year guarantee

All pipes have three layers to provide the highest mechanical performance.

• External black PP layer provides excellent impact resistance and long-term UV protection
• Intermediate PP-MD layer provide high mechanical resistance and excellent soundproofing performance.
• Internal Layer low-friction white PP layer provides the best flow performance, high resistance to chemical agents and high-definition contrast for visual monitoring.
