The RainBarrier HD (heavy density) is a rigid insulation board with a consistent 6.0pcf density throughout, eliminating the need to orient the insulation in a certain direction. The mineral wool board is non-combustible and provides R-values of up to 4.2 per inch of thickness. Mineral wood continuous insulation is commonly used in masonry cavity construction and open joint façade systems.
