Superior compressive strength

Why choose mineral wool insulation?

Thermafiber® RainBarrier® ci High Compressive insulation uses ThermaCrimp™ technology to make the highest compressive strength mineral wool continuous insulation on the market. This continuous insulation is designed to be installed behind any type of cladding, including combustible and open-joint assemblies. These mineral wool insulation products provide reliable thermal performance and structural support for exterior walls in commercial applications. They are available in different compressive strengths, depending on the exterior wall material and the building's structural design.

Key Benefits of High Compressive Strength Insulation:

  • Provides mineral wool continuous insulation solutions for exterior walls with lightweight, medium-weight, or heavy cladding options.
  • Allows exterior wall materials to be attached without damaging the insulation.
  • Covers the wall continuously to help protect against heat and cold.
  • Fits behind many types of outer walls, even ventilated or special designs.
  • Available in three compressive strength levels: 80, 110, and 140.

Applications

Because wall cavities are often already insulated, adding mineral wool continuous insulation to the exterior is an effective way to improve R-value. Thermafiber® RainBarrier® High Compressive insulation products provide continuous insulation that helps limit heat loss through the framing, improving overall energy efficiency.
