75mm Isover RD Party Wall Insulation Roll (7.74m2/Roll)

Isover RD Party Wall Insulation Roll measuring 75mm thick and covering 7.74m² per roll is a high-performance glass mineral wool designed for use in separating masonry party walls. The roll is resilient, strong, and pre-cut to 2 x 455mm widths to fit standard wall tie spacings with precision and minimal waste. Engineered to exceed the acoustic performance standards set out in Building Regulations Approved Document E (England and Wales), Isover RD is a proprietary component of Robust Detail constructions E-WM-17, E-WM-20, and E-WM-24. The 75mm thickness provides an effective part-fill solution that improves acoustic control in separating walls where reduced cavity depth is specified. Manufactured from up to 86% recycled glass, Isover RD Party Wall Roll combines outstanding sustainability credentials with consistent product quality. When used as part of a correctly detailed full-fill Robust Detail construction with mineral wool edge barriers, it can help achieve a zero U-value in accordance with Approved Document L1A, Table 3, providing both acoustic and thermal efficiency within party wall systems.
