Brush Panels vs Cable Grommets: Sealing Performance Compared
Brush panels and brush grommets seal different openings in different planes. Here is when to use each and why most facilities need both.
How Unsealed Cable Openings Undermine Your Containment Investment
Containment panels seal the aisle, but unsealed cable cutouts in the floor bleed cold air and reduce performance. Here is how to find and fix every leak point.
The Relationship Between Raised Floor Height and Cooling Capacity
Plenum depth sets the ceiling on how much cooling your raised floor can deliver. Here is how floor height affects tile output and what to do when the floor limits your capacity.
Why Floor Tile Placement Is the Most Overlooked Cooling Variable
Most data centres place floor tiles based on convenience, not thermal demand. Here is how to audit tile placement and rebalance airflow delivery to eliminate waste.
Raised Floor vs Overhead Cooling: Which Delivers Better Results in 2026
Raised floor cooling is not dead, but it is not right for every facility. Here is how raised floor and overhead cooling compare on performance, flexibility, and cost in 2026.
Containment in Colocation: Who Pays, Who Benefits, and Who Decides
Containment in colocation stalls because providers bear the cost and tenants capture the benefit. Here is how to break the deadlock with practical cost-sharing models.
Containment Retrofits: Real Costs, Timelines and Results
Retrofitting containment into a live data centre is complex. Here is what the project actually involves: costs, timelines, phased installation, fire suppression review, and measured results.
Hot Aisle vs Cold Aisle Containment: The ROI Numbers Nobody Talks About
Containment improves PUE and cuts cooling costs, but most articles skip the financial framework. Here is how to calculate real ROI for your facility.
Blanking Panel Materials Compared: ABS Plastic vs Steel vs Foam
ABS, steel, and foam blanking panels each perform differently on fire safety, reusability, and long-term cost. Here is how to choose the right material for your data centre racks.
Liquid Cooling vs Air Cooling: Where Blanking Panels Still Matter
Liquid cooling does not eliminate the need for blanking panels. Hybrid facilities, rear-door heat exchangers, and AI transitions all depend on proper airflow management.
The Compliance Gap: Fire Ratings and Safety Standards for Data Centre Rack Accessories
Most data centres invest in fire suppression but never check the fire rating of the blanking panels inside their racks. Here is how to close the compliance gap.
How Long Do Blanking Panels Actually Last? A Product Lifespan Analysis
Blanking panels fail when material, mounting design, and environmental conditions work against them. Here is how to predict lifespan and calculate the real lifecycle cost.
The Role of Brush Grommets in Cable and Airflow Management
A brush grommet is a bristle-lined seal installed at cable entry points in raised floors, server racks, and enclosures. It allows cables to pass through openings while blocking conditioned air from escaping, preventing dust ingress, and protecting cable jackets from...
Cold Aisle vs Hot Aisle Containment: Which Is Right for Your Data Centre?
Neither cold-aisle containment nor hot-aisle containment is universally superior. Cold aisle containment (CAC) encloses server intakes to protect the conditioned air supply, while hot aisle containment (HAC) captures exhaust air and returns it to cooling units. The...
How to Reduce Thermal Recirculation Without Adding More Cooling Units
How to Reduce Thermal Recirculation Without Adding More Cooling Units Thermal recirculation occurs when hot exhaust air from server racks returns to server intakes rather than being routed to CRAC or CRAH units, raising rack inlet temperatures and reducing effective...
How Directional Airflow Floor Tiles Improve Cooling Efficiency
Directional airflow floor tiles are engineered raised floor components that channel cold air precisely toward server rack intakes, reducing wasted cooling capacity and eliminating hotspots in data centre environments. Unlike standard perforated tiles that disperse air...
What Is a Blanking Panel? Thermal Function, Sizes & Use Cases
A blanking panel is a modular rack insert, typically 19-inch or 23-inch wide, designed to seal unused rack units (U) in server cabinets, preventing hot exhaust air from recirculating into cold intake zones and eliminating energy-wasting bypass airflow. In modern data...
How Do AI Data Centres Manage Heat in High-Density GPU Clusters?
AI workloads are redefining the thermal design requirements of data centres. When clusters consist of thousands of GPUs operating simultaneously, heat becomes a performance constraint, not just a facilities concern. The scale of energy consumption, thermal output, and...
