Product Information
dB Acoustic Lag 50 – Lightweight Acoustic Lagging for Residential, Commercial & Industrial Use.
dB Acoustic Lag 50 is a high-performance, lightweight acoustic lagging solution designed to reduce noise transmission in ductwork, piping systems, and enclosures. This flexible sound barrier combines Class 0 fire-rated protection with excellent acoustic insulation, making it ideal for industrial and commercial applications where weight reduction is essential.
Key Features & Benefits:
- Effective Noise Reduction – Achieves an average Sound Reduction Index (SRI) of 38 dB, significantly minimizing airborne noise from HVAC systems, piping, and enclosures.
- Multi-Layer Composite Design – Constructed with a 5 kg/m² mass-loaded acoustic barrier bonded to fiberglass quilt with a Class 0 aluminum foil facing, ensuring superior noise insulation and flexibility.
- Class 0 Fire Rating – Fully compliant with UK Building Regulations (BS 476 Parts 6 & 7), offering exceptional fire resistance and enhanced safety in industrial environments.
- Lightweight & Flexible – With a total weight of 5.54 kg/m² and a thickness of 15.25 mm, it provides an optimal balance between performance and ease of handling.
- Thermal & Chemical Resistance – Operates in temperatures from -20°C to 93°C, with low thermal conductivity (0.033 W/mK at 0°C) for improved energy efficiency.
- Durable Foil Facing – The silver/yellow aluminum foil offers additional protection against moisture, oils, and mechanical damage, ensuring long-term durability.
Applications:
✔ HVAC Ductwork & Ventilation Systems – Reduces noise transmission while improving thermal efficiency.
✔ Industrial Piping & Equipment – Controls operational noise in factories, power plants, and mechanical rooms.
✔ Acoustic Enclosures & Machinery Housing – Enhances soundproofing in manufacturing and commercial settings.
dB Acoustic Lag 50 is the go-to mufti-lag solution for environments requiring effective noise control without excessive weight, making it a practical choice for DIYers, engineers and installers.
Construction: Class 0 Alumium foil facing – 10kg/m2 Acoustic barrier – 25mm quilted glass.
