ArmaSound® RD240

ArmaSound RD240 is a sound absorbing foam insulation designed for use in demanding environments such as the oil and gas industry. As a high-performance sound absorber, it offers an additional barrier (transmission loss) performance and both vibration damping and de-coupling (isolation) properties.

Delivering optimal performance at lower thicknesses than traditional materials, ArmaSound RD240 is a uniquely advanced open-cell acoustic insulation material. Depending on the thickness chosen, ArmaSound RD240 offers excellent sound absorption behaviour across the frequency range.

With a density much greater than traditional acoustic absorption materials, it is also suitable for some applications that may call for an acoustic airborne noise barrier.

ArmaSound RD240 provides a dust- and fibre-free solution and satisfies acoustic classes 6, 7 and 8 according to NOSOK R-004.

The acoustic properties of ArmaSound RD240 varies depending on formulation, density and thickness. The best results will be achieved by selecting the most appropriate product grade for the type of noise in question (e.g. airborne noise, structural noise).  

Key features
