Unique construction combines the superior transmission loss performance of the noise barrier with the high absorption properties of the decoupling, non-combustible glass-wool. The acoustic pipe lagging is also quilted with a fabric covering that prevents it from shedding irritating fibers, while facilitating handling.

Sonic-Shield’s^® Soundlag™ NL-QGW was developed to reduce noise break-out from pipes, valves, fan housings and ductwork in commercial, industrial and domestic buildings. Applications range from hydraulic and waste pipe, to HVAC ducting, to virtually all plumbing and hydrostatic situations.

The lightweight 25-millimeter thick, non-combustible, glass-wool layer breaks the vibrational path between the decoupled mass barrier and the substrate to which it is bonded. This helps optimize performance as the vinyl external wrap remains flexible at all times.

Construction of the acoustic lagging also includes a tough external aluminum foil facing and an external barrier wrap. It is classified as a low volatile organic compound (VOC) emitting material with its heat and light reflective facing and ignition retardant barrier layer.
