Insulated High Speed Door — RAX Door Technology
01 · Overview

Speed Meets Thermal Performance

Insulated high speed doors combine the rapid operation of high performance doors with the thermal efficiency of insulated sectional doors. Unlike standard fabric high speed doors that offer minimal insulation, insulated high speed doors use rigid PU foam panels (40–50 mm) that maintain climate control while opening at speeds up to 2 m/s. This makes them ideal for cold storage, food processing, and any environment where temperature stability and frequent access are both critical.

RAX manufactures insulated high speed doors with double-skin galvanized steel panels filled with high-density PU foam (density 42–48 kg/m³), achieving U-values as low as 0.5 W/(m²·K). Servo motor drive with frequency converter ensures smooth, controlled operation. Inter-panel EPDM seals and perimeter weatherstripping minimize air infiltration. Wind resistance rated to Class 3 (700 N/m²) per EN 12424.

Insulated high speed doors are essential for cold storage facilities, food and pharmaceutical clean rooms, climate-controlled warehouses, and any application where energy loss during frequent door cycling must be minimized.

02 · Key Features

Engineered for Temperature-Sensitive Environments

Insulated Panel Construction

40–50 mm PU foam core (density 42–48 kg/m³) between double-skin galvanized steel. U-value as low as 0.5 W/(m²·K). Significantly reduces energy loss compared to single-skin fabric high speed doors.

High-Speed Operation

Opening speeds up to 2 m/s with servo motor drive. Frequency converter for smooth acceleration/deceleration. Minimizes temperature exchange during each opening cycle.

Superior Sealing

Inter-panel EPDM seals + perimeter weatherstripping on all four sides. Bottom seal with brush/wiper design adapts to uneven floors. Minimizes air infiltration and energy loss.

Cold Chain Integrity

Fast operation + insulation = minimal temperature fluctuation. Critical for cold storage (-25°C to +5°C) and food/pharma environments. Reduces refrigeration load and energy costs.

Safety Systems

Photocells, pressure-sensitive bottom edge, emergency stop. Compliant with EN 12453. Optional light curtains for enhanced personnel protection in high-traffic areas.

Smart Control

PLC-based control with LCD display. Programmable speeds, delay times, partial opening. Remote operation and diagnostics. Integration with BMS and WMS systems.

Where Insulated High Speed Doors Excel

Cold Storage Facilities

Freezers (-25°C) and chillers (+5°C) require minimal temperature fluctuation during frequent access. Insulated panels + fast operation = reduced refrigeration load and energy savings of 30–60% vs. standard doors.

Food Processing Plants

HACCP-compliant environments require temperature control and hygiene. Smooth steel surfaces easy to clean. Fast operation maintains positive pressure and prevents contamination ingress.

Pharmaceutical Clean Rooms

GMP environments require strict temperature and pressure control. Insulated high speed doors maintain clean room classification while allowing frequent material and personnel access.

Climate-Controlled Warehouses

Distribution centers with temperature zones (ambient, chilled, frozen). Insulated doors prevent cross-contamination between zones. Fast operation supports high-throughput logistics.

Dairy & Beverage Production

Temperature-sensitive production lines require stable environments. Insulated doors minimize thermal shock to products. Hygienic design meets food safety standards.

Logistics Cold Chain

Loading docks with temperature-controlled staging areas. Fast door operation reduces truck wait times. Insulated panels prevent condensation and ice buildup on door surfaces.

06 · Compliance

Applicable Standards

EN 13241:2003+A2:2016

Core CE product standard for industrial, commercial, and garage doors. Covers both manual and powered doors. Requires Declaration of Performance (DoP) under CPR 305/2011.

EN 12453:2001

Safety requirements for powered doors. Specifies force limiting, safety devices, and control system requirements. High speed doors must comply with enhanced safety standards.

EN 12424:2000

Wind load resistance classification. Defines Classes 0–5. Insulated high speed doors typically achieve Class 3 (700 N/m²) with rigid panel construction.

CE Marking

Mandatory for export to EU/UK markets. Indicates compliance with EN 13241 and CPR 305/2011. RAX provides CE technical file and Declaration of Performance with every shipment.

How much energy do insulated high speed doors save?

Compared to standard fabric high speed doors, insulated doors reduce energy loss by 30–60% in cold storage environments. The combination of fast operation (minimizing open time) and PU foam insulation (reducing heat transfer) maintains temperature stability and reduces refrigeration load.

What is the U-value of insulated high speed doors?

U-value approximately 0.5 W/(m²·K) with 40–50 mm PU foam core (density 42–48 kg/m³). This is comparable to insulated sectional doors but with 5–10× faster operation. Inter-panel EPDM seals and perimeter weatherstripping further reduce air infiltration.

Can these doors operate in -25°C environments?

Yes. Insulated high speed doors are designed for cold storage applications from -25°C to +50°C. Special cold-chain variants include heated bottom seals to prevent ice buildup, anti-condensation panel coatings, and cold-rated motor components.

What safety features are included?

Standard: photocells, pressure-sensitive bottom edge, emergency stop. Optional: light curtains, safety edges on vertical sides. All compliant with EN 12453 safety requirements for powered doors.

Do you provide installation?

No — RAX is a pure manufacturer. Doors ship with English installation manuals, wiring diagrams, and remote support. We recommend using a qualified local installer who can verify structural capacity and proper electrical connection.

What is the lead time and warranty?

Standard configurations: 12–20 days. Custom first order: 20–35 days. Repeat orders: 15–20 days. Warranty: panels 10 years, motor and control system 5 years. Warranty replacement parts shipped via DHL/FedEx in 5–7 days.
