Kingflex insulation, known for its elastomeric foam structure, has a high water vapor diffusion resistance, indicated by a μ (mu) value of at least 10,000. This high μ value, along with low water vapor permeability (≤ 1.96 x 10⁻¹¹ g/(m·s·Pa)), makes it highly effective at preventing moisture ingress.
Here’s a more detailed breakdown:
μ Value (Water Vapor Diffusion Resistance Factor):
Kingflex insulation has a μ value of at least 10,000. This high value signifies the material’s excellent resistance to water vapor diffusion, meaning it effectively blocks the movement of water vapor through the insulation.
Water Vapor Permeability:
The water vapor permeability of Kingflex is very low, typically ≤ 1.96 x 10⁻¹¹ g/(m·s·Pa). This low permeability indicates that the material allows very little water vapor to pass through it, further enhancing its ability to prevent moisture-related problems.
Closed-Cell Structure:
Kingflex’s closed-cell structure plays a crucial role in its moisture resistance. This structure creates a built-in vapor barrier, minimizing the need for additional external barriers.
Benefits:
The high water vapor resistance and low permeability of Kingflex contribute to several benefits, including:
Condensation control: Preventing moisture from penetrating the insulation helps to avoid condensation issues, which can lead to corrosion, mold growth, and reduced thermal performance.
Long-term energy efficiency: By maintaining its thermal properties over time, Kingflex helps to ensure consistent energy savings.
Durability: The material’s resistance to moisture helps to extend the lifespan of the insulation and the overall system.
