Data Center Curtains | Server Room Air Containment Solutions

Steel Guard Safety’s data center curtains provide an economical and highly effective solution for controlling server room temperatures through hot aisle and cold aisle air containment. By isolating hot and cold airflow zones, our data center air containment curtains eliminate hot spots, reduce overcooled zones, and significantly lower energy consumption — without the cost or disruption of permanent infrastructure changes.

All Steel Guard data center curtains are custom designed to fit your specific server room layout. Manufactured from high-grade PVC materials superior to retail alternatives, our curtains install easily using direct ceiling mounts, drop-down lanyard mounts, or intelligent fuse-link ceiling mounts that release at 135°F for fire safety compliance.

Benefits of Data Center Air Containment Curtains

• Eliminates hot spots — improves air distribution by isolating hot and cold zones for consistent cooling across all server racks
• Reduces energy costs — prevents cold air from being wasted on surrounding areas, directing it precisely where servers need it
• Enhances uptime — reduces hardware stress by maintaining optimal operating temperatures between 70°F and 75°F
• Optimizes rack capacity — improved temperature control allows for better server population and increased rack density
• Extends equipment life — minimizes thermal wear and tear for longer hardware lifespan and reduced replacement costs
• Easy installation — installs by your maintenance staff without structural modifications, or retrofits over existing drop ceilings
• Fire safety compliant — intelligent fuse-link ceiling mounts release at 135°F, integrating seamlessly with fire suppression systems

Hot Aisle Containment Curtains

Hot aisle containment isolates hot exhaust air as it travels from server rear panels to the CRAC (Computer Room Air Conditioning) return units. By containing exhaust air before it can mix with cold supply air, hot aisle containment dramatically improves cooling efficiency and reduces the workload on your air conditioning systems. This method is particularly well-suited for new enterprise data center construction due to its ease of integration during initial build-out.

Steel Guard hot aisle containment curtains are available in stationary anti-static clear curtains, strip curtains with ceiling or drop-down mounts, retractable soft wall curtains, and accordion data track curtains. View Hot Aisle Containment Curtains →

Cold Aisle Containment Curtains

Cold aisle containment focuses on isolating cold supply air delivered through perforated floor tiles, ensuring it reaches server air inlets directly rather than being dispersed into the surrounding environment. Cold aisle containment is ideal for retrofitting existing data center facilities — it avoids the need to modify fire suppression systems and adapts easily to existing obstructions like cable trays. Cold aisle systems handle high thermal loads of up to 10–15kW with a raised floor setup.

Steel Guard cold aisle containment options include stationary clear curtains, soft wall retractable curtains, accordion retractable curtains, and strip curtains with ceiling or drop-down mounts. View Cold Aisle Containment Curtains →

Hot Aisle vs. Cold Aisle — Which Is Right for Your Facility?

Both containment strategies reduce energy costs and improve server performance — the right choice depends on your facility’s existing infrastructure and project scope.

• New construction or major renovation — hot aisle containment is typically easier to integrate and provides a more modern approach to airflow management
• Retrofitting an existing facility — cold aisle containment is generally simpler to implement without modifying fire suppression systems or existing infrastructure
• High thermal load environments — cold aisle containment with raised floor setup handles up to 10–15kW per rack
• Legacy infrastructure — cold aisle systems adapt more easily to existing cable trays and ceiling obstructions
