Thermafiber RainBarrier Dark mineral wool insulation from Owens Corning sports an adhesively bonded dark-colored fiberglass facing meant to make the continuous insulation less visible in open-joint cladding applications. The maker says the facing material isn’t prone to the cracking that can occur with more rigid materials. Like other RainBarrier products, Dark 45 and Dark HD are noncombustible, fire-resistant, and vapor permeable and contain a minimum 70% recycled content, according to the manufacturer. owenscorning.com/rainbarrier
