An Insulated High-Speed Door is a high-performance industrial door system designed to balance rapid operational speed with superior thermal efficiency.
Unlike standard fast doors, it features a specialized insulated curtain (typically constructed with double-layered PVC and high-density foam filling). This design minimizes heat transfer and prevents energy loss, making it an essential solution for environments that require strict temperature control and high-frequency access.
Our insulated high-speed doors feature multi-layer sandwich curtains filled with high-density foam, significantly reducing heat transfer and maintaining stable internal temperatures for cold storage and climate-controlled facilities.
Equipped with specialized heavy-duty side seals and a flexible weighted bottom edge, these doors create a near-hermetic seal to eliminate drafts and minimize energy loss between different temperature zones.
The high-speed opening and closing cycles minimize the duration of air exchange, effectively preventing the loss of cold or heated air, which drastically cuts energy costs in high-traffic industrial environments.
Designed for extreme environments, our doors can be equipped with integrated heating cables in the tracks to prevent ice buildup, paired with advanced controllers to ensure smooth, frost-free performance in sub-zero conditions.
The following are the standard parameters for two different types of insulated doors. All dimensions and configurations can be fully customized to meet the specific requirements of your facility.

Product details showcase， every detail of each door is meticulously crafted.
Features a high-density PU foam core for superior thermal insulation. Effectively reduces energy loss and maintains precise temperatures for cold-chain environments.
A heavy-duty synchronized system that distributes torque across dual shafts. Provides precise control and smooth operation for large-scale industrial curtains.
Secures the curtain into tracks to create an airtight seal against dust and pests. Includes a self-repairing design that withstands extreme wind loads.
Built-in heating elements prevent ice buildup on guides and seals. Ensures reliable operation and high-performance sealing in sub-zero freezer conditions.
Advanced sensors immediately reverse door movement upon contact. Maximizes safety for personnel, vehicles, and equipment during high-speed operation.
Available in various RAL colors to match your branding and architecture. High-visibility options are also available to enhance workplace safety.
For large distribution centers, Stacking Insulated Doors are often installed at external loading bays. They protect the interior from outside weather extremes (heat or cold) and high wind pressure, ensuring that the energy used to climate-control the warehouse isn’t wasted when trucks are docking.
This is the most common application. These doors act as a thermal barrier to maintain sub-zero temperatures. They prevent heavy energy loss during high-frequency traffic and help stop frost or ice from forming around the door opening, which is critical for frozen food safety.
In facilities where “cold chain” integrity is vital, these doors separate different temperature zones—such as raw material storage, processing areas, and packaging lines. They ensure that fresh produce, meat, or dairy products remain at the required temperature to prevent spoilage and meet hygiene standards.
SEPPES has cooperation customers with more than 60 Fortune 500 companies such as Pepsi, Logitech, Huawei, and Procter & Gamble.

The Dual-shaft Insulated Door is designed for high-frequency internal use, featuring double-track synchronization for maximum speed and air-tightness. The Fold-up (Stacking) Insulated Door uses high-strength belts to lift the curtain, making it ideal for large external openings where high wind resistance and thermal retention are both required.
Both models utilize double-layer thermal curtains (often filled with specialized insulation materials). By combining high-speed operation (up to 1.5m/s) with superior sealing, they minimize the “exchange time” between cold and warm air, significantly reducing refrigeration energy costs.
Yes. The Fold-up Stacking Door is equipped with horizontal wind-resistant aluminum or steel bars. This structural design allows it to maintain its insulation performance even in high-pressure environments or external warehouse entrances exposed to heavy wind loads.
