Robust Details E-WM-24 incorporates Isover RD Party Wall Roll, aircrete blocks manufactured by APA members and a standard 8kg/m³ plasterboard. It offers house builders the option to build a high performing separating masonry wall using aircrete blocks without the need for a wet parge coat, achieving three credits towards the Code for Sustainable Homes.
The detail, developed with the APA, exceeds regulation compliant thermal and acoustic performance for the separating wall element, Isover said. It also offers enhanced thermal detailing in terms of PSI value performance at the separating and external wall junction, which can improve SAP scores.
Isover described it as “a good example of how collaboration between companies within the construction sector can result in beneficial solutions for the market”.
Users of the newly approved solution will be able to meet the full-fill requirement to help deliver a zero U-value party wall with no wet parge coat prior to drylining. If the detail is used under the Robust Details scheme it will also automatically comply with acoustic requirements of Part E of Building Regulations without the need for pre-completion testing (PCT).
The E-WM-24 Robust Details approved solution is one of three Saint-Gobain Isover constructions that feature Isover RD Party Wall Roll as a proprietary material.
