A solution for every project
The Silenta range offers three system levels to match different performance requirements, enabling the right balance of acoustic comfort, durability and cost efficiency.
• Silenta Premium — The highest level of acoustic performance for demanding environments such as luxury residential, healthcare and premium commercial buildings. Its multi-layer composite structure delivers exceptional sound insulation, while advanced gasket technology ensures secure connections and long service life where acoustic performance is critical.
• Silenta 3A — Proven acoustic comfort for mainstream residential and commercial projects, balancing performance and value. Its three-layer construction reduces drainage noise while maintaining strong durability and straightforward installation, making it a trusted choice for multi-occupancy buildings.
• HT-PP — A dependable, lightweight drainage solution where acoustic performance is not the primary driver. Offering excellent chemical and temperature resistance with simple installation, it is ideal for straightforward or cost-sensitive applications.
All systems share high-quality polypropylene construction, reliable sealing technology and a comprehensive range of pipes and fittings — ensuring flexibility across applications with consistent installation practices.
Why acoustic drainage matters
Noise from drainage systems can travel through pipe walls and building structures, disrupting sleep, concentration and comfort. Acoustic performance is increasingly recognised as a key measure of building quality, influencing wellbeing and residence satisfaction. Silenta’s multi-layer construction absorbs sound at source, reducing airborne and structure-borne noise.
You’ll never think about drainage noise… unless you hear it.
