The 110mm Knauf Timber Frame Party Wall Slab is a premium glass mineral wool slab engineered for timber frame party walls, delivering exceptional thermal and acoustic performance. This 110mm non-combustible slab achieves the highest Euroclass A1 fire rating and features our advanced bio-based binder, ECOSE® Technology.
The 110mm Knauf Timber Frame Party Wall Slab delivers thermal and acoustic insulation to timber frame party wall cavities through friction-fit installation between timber studs. This product functions as a comprehensive fill solution, enabling zero effective U-value achievement within SAP calculations.
Glass and rock mineral wool products install more reliably than alternatives such as rigid boards, as they conform to substrate irregularities and bond seamlessly, preventing air pockets. Mineral wool technology accommodates substrate imperfections and long-term movement, maintaining consistent contact and preserving thermal effectiveness throughout the building's lifespan. Eliminating air gaps proves essential for delivering genuine performance in the intended application. Any insulation material failing to achieve 'as-built' thermal performance compromises its core function, creating unnecessary risk as the construction sector works to eliminate the performance gap.
