Knauf Party Wall Slabs are high-performance glass mineral wool insulation solutions designed to reduce sound transmission and improve fire resistance in separating walls between dwellings. Whether you’re working with timber frame or masonry construction, choosing the right insulation is key to ensuring compliance with Building Regulations (Approved Document E) for acoustic performance and Approved Document B for fire safety.
Knauf Timber Frame Party Wall Slab is specifically designed for lightweight timber frame constructions, offering excellent sound absorption to minimise noise transfer between adjoining properties. It is a non-combustible (Euroclass A1 fire-rated) solution that also helps to reduce unwanted air movement, improving overall thermal efficiency. Its flexible yet dense structure ensures a snug fit within timber stud cavities, making installation quick and effective.
On the other hand, Knauf Masonry Party Wall Slab is optimised for traditional masonry party walls, providing outstanding acoustic insulation by reducing flanking sound transmission through the cavity. This dense, rigid slab is designed to fit tightly between masonry leaf's, delivering long-term fire protection and moisture resistance while contributing to zero U-value calculations when used as part of a fully filled party wall system.
Both timber frame and masonry party wall slabs offer superior acoustic performance, non-combustibility, and ease of installation, ensuring compliance with Part L, E, and B of Building Regulations. Choosing the right option depends on your construction type, with Timber Frame Party Wall Slab best suited for lightweight structures, while Masonry Party Wall Slab is ideal for brick and block cavity walls.
