RainBarrier Heavy Density (HD)
Thermafiber has released a continuous insulation product, RainBarrier HD (Heavy Density), a rigid insulation board with a consistent six pcf density throughout the entire thickness. The consistent density simplifies installation by eliminating the need to orient the insulation in a certain direction. The increased density enhances the rigidity and ease of fabrication. The mineral wool board is non-combustible and provides exceptional R-values of 4.2 per inch of thickness. RainBarrier HD is permeable, controls sound and is available with up to 90 percent certified-recycled content.
