Advantages

• Pre-cut rolls friction fit snugly between timber studs, stopping air leakage and heat loss effectively.
• Available in convenient pre-cut widths of 2x570mm or 3x380mm to match standard timber stud spacing.
• Mineral wool construction provides excellent sound absorption and acoustic performance superior to many alternative insulation options.

Application

Knauf FrameTherm 32 90mm Rolls suit insulation of external walls and warm pitched roofs in timber frame buildings. Timber frame walls generally deliver superior thermal performance compared to equivalent masonry construction. However, their lighter mass means insulation materials must provide enhanced acoustic qualities to compensate. FrameTherm 90mm rolls friction fit between studs to minimise heat loss while delivering acoustic absorption, improving overall wall performance.

Real Performance

Glass and rock mineral wool offers simpler installation than rigid board alternatives. The material adapts to minor substrate variations and interlocks seamlessly, eliminating air gaps. 90mm Mineral wool insulation accommodates substrate irregularities and structural movement, maintaining thermal contact and performance throughout the building's lifetime. Eliminating air gaps proves essential for genuine as-built thermal performance. Insulation that fails to deliver real performance undermines its purpose and creates unnecessary risk as the industry works to bridge the performance gap.
