Isover RD Party Wall Roll is designed for use in E-WM-17, E-WM-20 and E-WM-24 Robust Detail separating wall constructions to exceed acoustic performance requirements set out in Building Regulations Approved Document E (England and Wales). The product also conforms to the Robust Details generic full-fill mineral wool specification for all other masonry cavity separating details.

Significant cost savings can be obtained since there is no need for pre-completion testing and additional savings can be made with E-WM-17, E-WM-20 and E-WM-24 since they remove the need for wet plaster or parge coats prior to dry lining.

The strong, resilient and flexible glass mineral wool rolls are supplied in 75, 100, 125 and 150 mm thicknesses and are ready-cut to 2 x 455 mm to fit between standard wall tie spacing.
