The 125mm Isover RD Party Wall Roll is a glass mineral wool insulation product engineered to suppress sound transmission through masonry cavity separating (party) walls and restrict air infiltration within the cavity wall, boosting thermal efficiency. When incorporated into Robust Detail separating wall systems E-WM-17, E-WM-20, and E-WM-24, it removes the requirement for expensive pre-completion sound testing and can surpass the acoustic insulation standards set out in Building Regulations Approved Document E (England & Wales) by +5dB. The 125mm Isover RD Party Roll insulation rolls come pre-cut into 2 x 455mm sections to align with standard wall tie spacing.
