What is Phenolic Insulation?

Phenolic insulation is a type of rigid foam insulation made from phenolic resins. Known for its high thermal resistance and low thermal conductivity, it is used widely in both residential and commercial applications. Its unique attributes make it a preferred choice in industries requiring stringent fire safety standards.

Key Properties of Phenolic Insulation

  • Thermal Efficiency: One of the standout features is its superior thermal performance, with a low thermal conductivity of about 0.020-0.025 W/m·K.
  • Fire Resistance: Phenolic insulation materials exhibit excellent fire resistance, classified as Class 1 under UK fire regulations, which makes them suitable for a variety of applications.
  • Moisture Resistance: Thanks to its closed-cell structure, phenolic insulation can resist moisture, which is important for preventing mold and mildew.
  • Lightweight and Easy to Handle: The lightweight nature facilitates easier transportation and installation.

Applications of Phenolic Insulation
