Soundlag NL-GW

acoustic pipe lagging - fire retardant noise barrier with glass wool backing

Soundlag NL-GW is a high-performance composite acoustic lagging product consisting of an aluminium foil-faced, mass-loaded, flexible vinyl noise barrier laminated to a glass- wool decoupling layer. The product was developed to reduce noise break-out from pipes, valves, fan housings and ductwork in commercial, industrial and domestic buildings.

The unique construction of Soundlag™ NL-GW combines the superior transmission loss performance of the noise barrier, Wavebar®, with the high absorption properties of the decoupling glass-wool layer Sorberglass.

The decoupling layer breaks the vibrational path between the decoupled mass barrier and the substrate to which it is bonded. This allows the vinyl external wrap to remain flexible at all times, thereby optimising its performance. The tough external aluminium foil facing provides good mechanical protection from dirt, oil and dust and offers a fire resistant covering.

The external barrier wrap, Nonlite (NL), is highly fire retardant with enhanced self-extinguishing properties and low smoke and toxicity characteristics. The decoupling layer is a lightweight 25 mm thick, non-combustible, glass wool (GW).

Soundlag products are easily cut to size with a knife or scissors and installed in 3 easy steps: cut, wrap and tape; making it the most cost effective acoustic lagging product on the market.

Soundlag products contain no ozone-depleting substances and comply with European and Australian standards for Volatile Organic Compound emissions.
