Isover RD Party Wall Roll 6m x 455 x 100mm Pack of 2

The Isover RD Party Wall Roll 6m x 455 x 100mm (L x W x T) Natural Pack of 2 is a cost effective acoustic insulation used to reduce the passage of sound across a masonry party wall and minimise the air movement within the cavity, improving its thermal performance. The strong, resilient and flexible rolls are ready-cut to 1 x 455mm or split into 2 x 227.5mm rolls to fit between standard wall tie spacing. When used as part of Robust Detail separating wall constructions E-WM-17, E-WM-20 & E-WM-24, RD Party Wall Roll can achieve +5dB over acoustic performance requirements set out in Building Regulations Approved Document E (England & Wales). It can achieve a zero U-value for party walls, as defined in Building Regulations (Approved Document L1A, Table 3), when fully filling the party wall cavity and in combination with mineral wool filled cavity barriers at the edges of the cavity. When used as part of a proprietary Robust Detail construction, it removes the need for parge coats or wet plastering.
