Fire-rated PUF (Polyurethane Foam) panels are insulated sandwich panels designed for use in buildings requiring fire resistance, thermal insulation, and structural performance. These panels are commonly used in industrial buildings, cold storage, clean rooms, and prefabricated structures.
Key Features of Fire-Rated PUF Panels:
Core Material:
Polyurethane foam (PUF) with fire-retardant additives.
Offers high thermal insulation (low thermal conductivity ~0.022–0.028 W/m·K).
Facing Materials:
Usually GI (galvanized iron), PPGI (pre-painted galvanized iron), or aluminum sheets.
Coated for corrosion and fire resistance.
Fire Rating:
Typically classified by duration: 30, 60, 90, or 120 minutes of fire resistance.
Complies with standards like BS 476 Part 6/7, EN 13501, or IS 12458.
Thermal & Acoustic Insulation:
High R-value per inch.
Also provides good soundproofing.
Applications:
Cold rooms, server rooms, clean rooms, modular site offices, pharmaceutical facilities, etc.
Joint Types:
Tongue-and-groove joints ensure air-tight and fire-stopping continuity.
Limitations:
PUF is combustible; thus, panels must be treated with fire-retardant chemicals and used with caution in high-risk areas.
For higher fire resistance (beyond 2 hours), PIR (Polyisocyanurate) or mineral wool panels are preferred.
