Rockwool HP Partial Fill Cavity is a rigid mineral wool slab designed for cavity wall insulation applications. With a thermal conductivity (lambda) of 0.035 W/mK, it delivers excellent energy performance while maintaining breathability for moisture management. The 110mm thickness provides optimal U-value performance for standard cavity widths with partial fill installation.
