In modern data centres, efficient airflow management is critical to maintaining system performance, reducing energy consumption, and ensuring equipment longevity. One of the most effective strategies used today is hot aisle and cold aisle containment — but its success depends heavily on proper sealing.
Even small gaps in containment systems can lead to air leakage, temperature imbalance, and reduced cooling efficiency. That’s why selecting the right sealing materials, including high-performance tapes and foam solutions, is essential for contractors and facility managers.
Why Sealing Matters in Containment Aisles
Hot and cold aisle containment systems are designed to separate hot exhaust air from cold intake air. When properly sealed, they:
- Improve cooling efficiency
- Reduce energy consumption
- Maintain consistent temperatures
- Prevent hot and cold air mixing
- Extend equipment lifespan
However, poor sealing can compromise the entire system. Air leakage through panel joints, cable cut-outs, or access points can significantly reduce performance.
Common Sealing Challenges in Data Centres
Contractors working on containment systems often face:
- Irregular panel gaps and misalignments
- Movement and vibration from HVAC systems
- Complex cable penetrations
- Mixed material surfaces (metal, plastic, composite panels)
- Tight installation timelines
These challenges require sealing solutions that are flexible, durable, and easy to install.
Key Sealing Solutions for Containment Systems
1. Closed Cell Foam Sealing Tapes
Closed cell foam tapes are widely used for sealing joints between containment panels, doors, and structural frames.
They provide:
- Airtight sealing
- Compression to fill gaps
- Resistance to moisture and air leakage
- Long-term durability
A reliable option is FS690 EPDM foam tape.
FS690 is designed for both internal and external applications, offering strong adhesion and consistent sealing performance across a range of substrates.
2. Bonding Tapes for Panel Assembly
Bonding tapes are used to secure panels, insulation, and containment structures without mechanical fasteners.

For containment aisle construction:
- A7600 is suitable for high-strength panel bonding and structural applications
- V2800 offers versatile bonding for insulation and general sealing
These tapes help reduce installation time while maintaining a clean, professional finish.
3. Foam Tapes for Vibration and Gap Sealing
In addition to airflow control, foam tapes also help reduce vibration between panels and structural components.
FS870 neoprene foam tape provides:
- Cushioning between surfaces
- Improved sealing consistency
- Noise and vibration reduction
This is particularly useful in areas near mechanical equipment or high airflow zones.
Benefits of Using Foam Sealant Tapes in Containment Systems
Using purpose-designed sealing tapes in data centre containment systems offers several advantages:
Improved Energy Efficiency
Proper sealing reduces air leakage, allowing cooling systems to operate more efficiently.
Faster Installation
Self-adhesive tapes eliminate the need for curing time, speeding up project timelines.
Consistent Sealing Performance
Factory-controlled tape thickness ensures uniform sealing across all joints.
Reduced Maintenance
High-quality materials maintain performance over time, reducing the need for rework.
Best Practices for Sealing Containment Aisles
To achieve optimal performance:
- Clean and prepare all surfaces before applying tape
- Use appropriate tape thickness for gap size
- Apply consistent pressure during installation
- Seal all joints, edges, and penetrations
- Inspect containment systems before commissioning
Attention to detail during installation ensures long-term system efficiency.
Supporting Data Centre Performance in Australia
As data centre construction continues to grow across Australia, particularly in major hubs like Sydney and Melbourne, expectations around energy efficiency and performance are increasing.
Contractors must deliver containment systems that meet strict operational standards while staying within project timelines. Using reliable sealing solutions is a key part of achieving these outcomes.
Hot and cold aisle containment systems are only as effective as their sealing. Small gaps can lead to major inefficiencies, making proper material selection essential.
By using high-quality foam and bonding tapes such as FS690, FS870, A7600 and V2800, contractors can improve:
- Airflow control
- Cooling efficiency
- Installation speed
- Long-term reliability
