Flexible Fabricated Products
Furnace Door Fire Barrier Curtain
Code prefix FDC
The furnace door fire barrier curtain is used at continuous heat treatment furnace doors for insulation and fire blocking. It is suitable for a working range of 500 C to 1000 C, and customised solutions are available for special high-temperature requirements. At room temperature the material has insulation, flexibility and weather resistance, and it can be split and fitted around workpieces passing through the door. The curtain reduces heat loss from the furnace, limits oxide scale on workpieces, reduces heat spill to the surroundings and is simple to install.

01 — Product description
Blocking heat at the furnace door
The furnace door fire barrier curtain is mainly used for thermal insulation and fire blocking at continuous heat treatment furnace doors. It suits a working range of 500 C to 1000 C, and customised adaptation is available for special high-temperature requirements. At room temperature the material has insulation, flexibility and weather resistance, and the curtain can be split and fitted around workpieces passing through the door.
Product functions
- Reduces heat loss inside the furnace during operation and lowers energy consumption.
- Reduces oxide scale formation on workpiece surfaces, improving finished product quality and yield.
- Reduces the effect of furnace heat spill on the surrounding environment and improves the working area.
- Customised production to suit different equipment specifications and conditions.
- Simple and convenient installation.
Working condition suitability and restrictions
Suitable for fire blocking and insulation at industrial furnaces under dry, static, conventional workpiece passage conditions. Temperature resistance is set by the base material, so the curtain material must match the actual furnace temperature and over-temperature use is prohibited. Not suitable for strong acid or alkali corrosion, continuous high-speed high-temperature airflow erosion, long-term liquid immersion or high-frequency severe friction; over-condition use causes wear, hardening, damage and loss of insulation.
Usage precautions
- Cutting, processing and assembly release fiber dust; ventilate, wear dust protection and dispose of waste under local environmental regulations.
- Select and use strictly within the base material's rated temperature.
- Inspect regularly and replace when worn, cracked, hardened or damaged.
- All technical data are for reference; users should test suitability and follow relevant safety regulations.
02 — Characteristics

Cuts heat loss from the furnace during operation and lowers energy consumption.
Scale and quality
Reduces oxide scale formation on workpiece surfaces and improves yield.
Split fitting
Can be split and fitted for workpieces passing through the door.
Custom production
Made to different equipment specifications and working conditions.

Service limits
- Suitable for dry, static, conventional workpiece passage conditions; the temperature limit is set by the base material, so select it against the actual furnace temperature.
- Not for strong acid or alkali, continuous high-speed high-temperature airflow erosion, long-term liquid immersion or high-frequency severe friction.
- Over-condition use causes wear, hardening, damage and loss of insulation.
- Cutting and assembly release fiber dust; ventilate, wear dust protection and replace worn or cracked curtains.
