75mm Isover RD Party Wall Roll - 2 x 455mm x 8500mm

75mm Isover RD Party Wall Roll is a glass mineral wool insulation designed specifically for use within masonry cavity separating (party) walls. It helps to reduce sound transmission between attached dwellings and minimise air movement within the cavity, improving both acoustic and thermal performance. The rolls are ready‑cut to 2 × 455mm, making them ideal for fitting between standard wall tie spacing in party wall constructions. When installed as part of approved Robust Detail systems (E‑WM‑17, E‑WM‑20 and E‑WM‑24), Isover RD Party Wall Roll can deliver +5 dB above the acoustic performance requirements of Approved Document E, and removes the need for costly pre‑completion sound testing.

CHARACTERISTICS

• Reduces unwanted noise transfer between adjoining properties when used in Robust Detail constructions. 
• When fully filling the cavity and used with mineral wool cavity barriers, it can achieve a zero U‑value for party walls as defined in Approved Document L1A.
• Approved component for E‑WM‑17, E‑WM‑20 and E‑WM‑24, eliminating the need for pre‑completion testing. 
• Euroclass A1 Reaction to Fire - non‑combustible and suitable for use in all building types. 
• Manufactured using a combination of externally sourced recycled glass and internally recycled glass cullet, supporting sustainability goals. 
• Excellent indoor air quality - achieves Eurofins Indoor Air Comfort Gold Certification, the highest level of accreditation.
