NSL acoustic lagging can be installed to significantly reduce noise breakout from ductwork systems for both internal and external applications. This product is generally used to attenuate sections of ductwork that cannot be treated by other means (e.g. by an installation of a silencer within the duct).

 

Our standard lagging material comprises 50mm thick insulating slabs with a Class O fire rating and density of 100kg/m3. For external application, the lagging material is weatherproofed with venture clad sheeting, which can be painted to help camouflage the ductwork. Windows can be formed in the lagging material to provide full access to ductwork hatches.
