Fiberglass Needled Insulation Lagging Felt / Batt:
High Temperature, Heat & Flame Resistant and Thermal Insulating
1200°F / 550°C Service Temperature
This high temperature, heat & flame resistant thermal insulating (lagging) needled fiberglass insulation is fabricated from high quality type E fiberglass that will not burn and will withstand continuous exposure to temperatures of 1100°F / 593°C. This product can provide thermal insulation for equipment, valves, piping, exhaust systems and is often used as the filler material for insulating blankets and covers. Also provides personnel protection.
This material resists most acids and alkalis and is unaffected by most bleaches and solvents. It is highly flexible and conformable.
Available in 1/4", 1/2", 3/4" and 1" thickness.
Conforms to MIL-I-16411 Type II.
Meets US Coast Guard 164.009 for incombustible materials.
Meets MIL-I-24244 for corrosiveness.
Thermal conductivity (K) is .43 at 500°F and .536 at 649°F.
Needled Fiberglass Insulation
Benefits of our High-Temperature Fiberglass Heat Protection Products
Fiberglass offers excellent heat resistance, retaining more than half of its room temperature tensile strength at 675°F / 357°C, and more than 25% at 875°F / 468°C. It begins to soften at 1500°F / 815°C and melts near 2050°F / 1121°C. Non-combustible and excellent thermal conductivity to dissipate hot spots; high resistance to chemicals and unaffected by UV light.
