Advantages

• Pre-cut to fit standard timber stud spacing (2x570mm or 3x380mm), enabling friction fitting that stops air leakage and heat loss through the insulation layer.
• Mineral wool construction delivers excellent sound absorption properties, outperforming many alternative insulation materials.
• Designed to accommodate minor substrate variations and building movement, maintaining thermal performance over the building's lifetime.

Application

140mm Knauf FrameTherm 32 Rolls suit external walls and warm pitched roofs in timber frame construction. Timber frame walls typically provide better thermal performance than comparable masonry walls, but their lower mass means acoustic insulation becomes essential. These rolls friction fit between studs to minimise heat loss whilst contributing to acoustic absorption, improving overall wall performance.

Real Performance

Glass and rock mineral wool installation is straightforward compared to rigid boards. The material adapts to substrate irregularities and interlocks seamlessly, eliminating air gaps. 140mm Mineral wool insulation accommodates substrate variations and building movement, ensuring continuous contact and sustained thermal performance. Eliminating air gaps is vital for achieving genuine thermal performance. Insulation that fails to deliver 'as-built' performance undermines its purpose and increases construction risk as the industry works to close the performance gap.
