Maximize Efficiency with Low U-Factor Insulated Doors

Cooling your sensitive IT equipment is a must, but it’s expensive—the National Renewable Energy Laboratory reports that cooling can represent as much as 40% of a data center's total utility costs.

Our Thermiser Max^® – Low U Door is engineered for the most demanding environments, making it the ideal choice for upper-floor loading bays and any opening where thermal efficiency is needed. With an exceptionally low U-factor of 0.532, it sets a new standard in energy efficiency.

These energy-efficient data center doors are engineered to minimize heat transfer:

• A mineral wool-insulated curtain
• Advanced perimeter seals
• Strategic thermal breaks

Together, these components work to maintain stable indoor temperatures, helping to protect servers and equipment from overheating. The Thermiser Max – Low U Door also offers sound attenuation (with an available Sound Transmission Rating of 27*) and can be labeled to meet strict energy codes like ASHRAE 90.1, IECC 2021, and California’s Title 24.

Alarm-Activated Rolling Fire Doors for Data Pods

The Rolling Fire Door with the AlarmGard^® Motor and SmokeShield^® package is a precision-engineered solution for reliable fire and smoke protection.

When a fire alarm is triggered or power is unexpectedly lost within a data pod, the integrated system activates. The fire door automatically closes, sealing the pod to protect critical infrastructure and slow the spread of fire and smoke, giving first responders time to act. With a fail-safe design and automatic reset, your doors adapt to emergencies and get you back to normal operation quickly once the alarm is cleared or power is restored.

Smoke and Fire Protection for Elevator Shafts

A fire’s "chimney effect" causes hot air and smoke to rise rapidly through elevator shafts, accelerating the fire's spread and hindering evacuations. The SmokeShield^® Elevator Smoke Curtain is designed to stop this.

This curtain seals and compartmentalizes the elevator opening. Once the elevator cycles, the SmokeShield system deploys the smoke curtain, and our GuideLock™ technology forms a tight barrier across the opening. Even if the hoistway is opened for emergency use, the system ensures protection. A manual override allows building occupants or firefighters to clear the hoistway for safety or access.

Springless, High-Cycle Security Doors for High-Traffic Openings

Data center entry and exit points rely on high-cycle reliability rather than high-speed operation. Loading docks, parking garage entrances, and utility bays all require the same thing—dependable, continuous performance that keeps operations moving. Cookson’s TruCycle™ Doors provide a major performance upgrade over standard service doors, offering a highly optimized solution for frequently used openings that don’t require high-speed doors. By completely eliminating high-maintenance components like traditional springs, TruCycle doors deliver an exceptionally long service life with minimal maintenance and downtime.

Available in both standard service and insulated (HCESD30) models, long-term performance is backed by our industry-leading 3-year or 500,000-cycle warranty. The insulated model features our standard Energy-Efficient Air Infiltration Package, which reduces air leakage by up to 94%* compared to standard doors.

For interior partitions where continuous airflow and frequent access are essential, the TruCycle Security Grille is the ideal choice. Its open-air design is perfectly suited for secure data center mechanical rooms, generator yards, and chiller enclosures, combining necessary ventilation with high-cycle durability, all backed by our leading 3-year or 300,000-cycle warranty.
