Sonic Liner is a flexible Glasswool insulation blanket faced with an acoustically permeable black woven glass cloth on the air stream surface. A 35 mm overlapping flange of the facing material is provided on both sides to enable effective sealing. It provides outstanding acoustical and thermal performance with low air friction.
- Lifelong energy savings
- Excellent thermal and acoustic properties
- Maintenance free
- Minimal air friction while optimising free duct area
- Safe application and use
- The air stream will not erode or release fibres into the air stream under normal operating conditions
