High Density Interior Phenolic Board

  • Air conditioning duct plate

  • WT


Phenolic fire-resistant insulation panels offer an effective solution for both fire protection and insulation in buildings. Weiteng's phenolic insulation panels are capable of withstanding high temperatures without melting or softening. They also produce minimal smoke, do not spread flames, and are resistant to flame penetration. These panels possess excellent fire resistance properties and provide efficient insulation, resulting in energy savings. The combination of superior fire resistance and energy-saving benefits makes them suitable for external insulation on a wide range of walls.

Different applications of phenolic insulation panels include:

1) Double-sided composite aluminum casing (used for integrated wall insulation and decoration, as well as insulation ducts for air conditioning systems).

2) Single-sided color steel with aluminum foil (ideal for air conditioning ducts).

3) Single-sided galvanized iron sheet with aluminum foil (suitable for air conditioning ducts).

4) Surface composite with other materials, such as interface agents and mesh mortar (providing A-level fire resistance).
