Thermafiber Insulation Types & Uses

  • RainBarrier® 45 and RainBarrier® HD Continuous Insulation
Designed to efficiently drain water from a wall cavity system while providing an energy-saving R value of 4.3 per inch of thickness. The semi-rigid composition of this insulation allows it to conform to irregular spaces, which ensures a more continuous thermal barrier. These products are also UV resistant.
