Knauf Frametherm insulation is a high-performance glass mineral wool solution designed for timber frame walls, floors, and roofs, providing outstanding thermal efficiency, acoustic insulation, and fire resistance. Available in both roll and slab formats, as well as different thermal conductivities, each option is tailored to specific project needs, ensuring compliance with Building Regulations (Approved Document L for energy efficiency and Approved Document E for acoustic performance).
Knauf Frametherm Roll 32 is the most thermally efficient roll in the range, with a low thermal conductivity of 0.032 W/mK, making it ideal for energy-efficient timber frame buildings. It helps reduce heat loss, lowering energy costs while maintaining high acoustic performance. Knauf Frametherm Roll 35, with a thermal conductivity of 0.035 W/mK, offers a great balance between insulation performance and cost-effectiveness, making it suitable for both domestic and commercial applications. For projects where cost is a key factor, Knauf Frametherm Roll 40 provides a more economical option while still ensuring good thermal and acoustic properties. All Frametherm Rolls are lightweight, flexible, and easy to install, making them a popular choice for large-scale timber frame constructions.
For projects that require a rigid and stable insulation solution, Knauf Frametherm Slab 32 delivers superior thermal performance with a thermal conductivity of 0.032 W/mK. Unlike rolls, the dense structure of Frametherm Slab ensures a tighter fit between timber studs, reducing the risk of air gaps and improving overall insulation performance. This makes it the ideal choice for projects that demand maximum energy efficiency and durability.
Both Frametherm Rolls and Slabs are non-combustible (Euroclass A1 fire-rated), ensuring fire safety while providing long-term thermal and acoustic benefits. The choice between them depends on installation preference and performance requirements, with rolls offering flexibility and ease of handling, while slabs provide a more rigid, high-performance solution.
