90mm Knauf FrameTherm Roll 35 - Glass Mineral Wool ( Split 2 x 570mm )

90mm Knauf FrameTherm Roll 35 represent glass mineral wool rolls specifically crafted for utilization in timber frame applications positioned between studwork. These 90mm frametherm 35 rolls boast a thermal conductivity ranging from 0.032 W/mK to 0.040 W/mK. Distinguished by their non-combustible nature and the highest attainable Euroclass A1 reaction to fire classification, these 90mm insulation rolls are produced using our distinctive bio-based binder, ECOSE® Technology.

Advantages

• Engineered for friction fitting between timber studs, effectively preventing air movement and infiltration through or around the insulation, thereby minimizing heat loss.
• Rolls are pre-cut into dimensions of either 2x570mm or 3x380mm, catering to commonly used timber stud spacing.
• Crafted from mineral wool, offering superior levels of sound absorption and reduction compared to other widely used insulating materials.

Application

90mm Knauf FrameTherm 35 Rolls find application in insulating external walls and warm pitched roofs within timber frame constructions. Timber frame walls typically offer superior thermal insulation compared to masonry walls of similar thickness. However, the lower mass of timber walls necessitates insulation materials to deliver heightened acoustic performance to offset this difference. 90mm FrameTherm insulation Rolls are specifically engineered to friction fit between studs, effectively minimizing heat loss, and simultaneously contribute to acoustic absorption, thereby enhancing the overall acoustic performance of the wall.

Real Performance

Glass and rock mineral wool present a more straightforward installation process compared to alternative insulants like rigid boards. Their ability to conform to slight imperfections in the substrate and seamlessly interlock eliminates the presence of air gaps. 90mm Mineral wool insulation is designed to accommodate substrate irregularities and any settling or movement over time, ensuring continual close contact and preserving thermal performance throughout the building's lifespan. It is evident that the absence of air gaps is crucial for achieving actual performance in the intended application. Any insulation material that falls short of delivering 'as-built' thermal performance not only fails in its primary purpose but also introduces an unnecessary risk as the construction industry endeavors to close the performance gap.
