This insulated high speed door concept is tailored to cold storage, freezer rooms and temperature-controlled warehouses. It combines a multi-layer insulated curtain with rapid roll-up motion and tight sealing, so the opening supports both thermal control and fast logistics.
| Door Type | Insulated high speed roll-up door, interior or exterior use |
|---|---|
| Curtain Construction | Multi-layer insulated fabric curtain with thermal barrier and seals |
| Frame Material | Steel or aluminium frames with thermal breaks and insulated interfaces |
| Typical Max Size | Project-based; many designs support openings up to several meters wide and high |
| Opening Speed | High-speed operation, commonly up to around 80" per second or more, depending on size |
| Closing Speed | Controlled closing speed, often around half of opening speed for safety |
| Thermal Performance | Insulated curtain, thermal breaks and seals designed to reduce heat transfer and air leakage |
| Drive and Control | Direct-drive motor with variable-frequency control, integrated diagnostics and safety interfaces |
| Safety Features | Obstruction sensors, safety edges and emergency stop functions integrated into the system |
| Recommended Application | Cold storage, freezer rooms, chilled logistics, clean corridors in temperature-controlled facilities |
The curtain uses multiple layers of PVC-coated fabric or similar materials with an insulating core. Internal thermal breaks and stitched or welded seams are designed to minimise thermal bridges and maintain flexibility for rapid roll-up motion.
Frames and guides incorporate thermal breaks and seal lines to reduce heat transfer from warm to cold zones. Seals and brush or rubber interfaces limit air leakage around the curtain, contributing to stable temperature control at the opening.
Openings between cold rooms and ambient areas where rapid movement and temperature control are required.
Internal freezer compartments with large temperature differences, needing high-speed, insulated barriers.
Temperature-controlled loading docks and logistics corridors where air exchange must be limited.
It is used in cold and temperature-controlled facilities that need fast access while reducing heat loss and uncontrolled air exchange.
Multi-layer construction with insulating materials and thermal breaks reduces heat transfer through the curtain.
Speeds typically reach several feet per second, depending on door size and design.
By limiting air exchange time and improving thermal resistance, it reduces heat loss and energy demand.
Sensors and safety edges detect obstructions and control movement, protecting users and equipment.
Yes, with appropriate insulation, seals and optional heated guides to manage frost and ice.
Steel or aluminium frames with thermal breaks and sealed interfaces are commonly used.
A direct-drive motor with variable-frequency control allows adjustable speeds and integrated diagnostics.
Routine checks of curtain, seals, guides, sensors and drive components keep performance stable.
Technical data for speeds, leakage, insulation and recommended use support design and energy calculations.
