SoundPro solution for internal partition walls

New build, E2

Soundpro solutions have been designed to give insulation against airborne sound. The resistance to airborne sound of timber or metal frame walls, depends on the mass per unit area of the leaves, the cavity width, frame material and the absorption in the cavity between the leaves.

The Approved Document E introduces performance criteria for internal walls and floors. This is based on laboratory rating (Rw) for which a minimum value for airborne sound insulation of Rw 40dB is required.

ADE Section 5 internal wall type B gives examples of internal timber or metal joist floor constructions which should achieve this value.
