Thermal Insulated Industrial Folding Door Rock Wool Filled Bi Parting Folding Gate

Thermal‑insulated industrial folding door is designed for temperature‑controlled industrial sites. Adopting rock‑wool filled sandwich insulated door panels with multi‑point perimeter sealing structure, it effectively reduces heat transfer and cold‑hot air exchange. It retains multi‑leaf bi‑parting side‑folding characteristic, low overhead‑headroom requirement, support ground‑track or overhead‑hanging track two structural options. Manual and electric driving modes optional. Widely used for constant‑temperature workshops, cold‑storage auxiliary access and temperature‑controlled industrial warehouses.

Ordinary steel folding door lacks thermal‑insulated performance and cannot be used for temperature‑controlled premises. Thermal‑insulated industrial folding door uses rock‑wool sandwich insulated panels as main door‑leaf material, cooperates with multi‑circle EPDM rubber sealing system to improve air‑tightness. Door‑leaves fold and stack on both sides of opening when open. It solves large‑size passage demand while keeping thermal‑insulated effect, suitable for internal and semi‑external temperature‑controlled industrial access.

Rock‑wool filled insulated sandwich door panels; optional ground‑track / overhead‑hanging guiding‑track system; heavy‑duty reinforced hinges; high‑load roller assemblies; multi‑point EPDM rubber perimeter sealing; manual push‑pull or electric motor‑driven unit; position limit switches; anti‑collision rubber buffer; emergency‑stop & power‑off manual‑release device; optional insulated polycarbonate observation windows; optional remote‑control and access‑control interlock.

• Constant‑temperature production workshop large‑size access
• Cold‑storage auxiliary vehicle passage gate
• Temperature‑controlled industrial warehouse entrance
• Semi‑external thermal‑insulated plant gate requiring large‑opening passage

Reserve enough side‑stacking space for folded door‑leaves. Select ground‑track or overhead‑hanging‑track scheme according to site condition. For overhead‑hanging version, lintel or steel‑frame must satisfy bearing‑load requirement. Prepare power‑supply for electric‑driven configuration. We provide fabrication drawings for local installation team.

Check EPDM sealing strips aging condition regularly. Inspect hinges, rollers and guiding‑track working status every 6‑12 months. Lubricate moving components. Avoid hard impact scratching insulated‑panel surface. Test emergency‑stop and manual‑release function, replace worn sealing‑strip and roller accessories timely.
