For ductwork, pipes, enclosures and similar applications where a considerable reduction in the passage of noise is required.

Highly flexible acoustic insulation consisting of a three-part laminate, incorporating a spacer/ isolating layer, a flexible heavy mass layer and an outer vapour barrier.

Being of a laminated construction, it overcomes the need for a separate isolation layer (normally required beneath most forms of acoustic lagging).

Features and benefits:

• Easy and quick to apply.
• High acoustic performance.
• Applied as a single layer treatment.
• Highly durable.
• Low thermal conductivity.
• Highly flexible, and suitable for installation on smaller pipes.
• Available in four grades to suit different performance requirements.
• Tested at certified independent test laboratories to BS EN ISO 717-1 and BS EN ISO 10140-2.

See manufacturer's literature for test results on airborne sound transmission loss figures, as well as installation guidelines for different types of ductwork.
