Introducing Subzero Engineering’s Dissolvable Air Barrier (DAB) Panels - Safe Overhead Containment for Modern Data Centers

Subzero Engineering is pleased to announce the acquisition of the Dissolvable Air Barrier (DAB) Panels product line from Cambridge R&D, further expanding Subzero’s portfolio of data center containment solutions and reinforcing its commitment to safety, performance, and turnkey system delivery. 

DAB Panels are a unique overhead containment solution designed to provide effective airflow separation during normal data center operation while dissolving within seconds when exposed to water during sprinkler activation. This dissolvable design helps eliminate falling panel hazards and supports safer fire suppression outcomes—addressing a critical challenge found in traditional rigid overhead containment systems. 

“With this acquisition, we’re strengthening our ability to deliver truly integrated, safety-driven containment solutions,” said Shane Kilfoil, President of Subzero Engineering. “DAB Panels complement our existing containment portfolio and give our customers another proven option to address airflow management and fire safety without compromise.” 

DAB Panels are engineered for both hot aisle and cold aisle containment applications and offer a combination of airflow performance, safety, and installation flexibility. Made from EPA-certified, plant-based cellulose materials, the panels achieve Class A fire and smoke performance, producing low heat and minimal smoke while maintaining visibility for emergency personnel. 

Despite their dissolvable design, DAB Panels remain durable during normal operation—withstanding high static air pressure and maintaining airflow separation where it matters most. Panels can be easily modified in the field to accommodate varying cabinet heights and existing infrastructure, eliminating the need to relocate sprinkler heads and reducing installation time and cost. 

DAB Panels integrate seamlessly across Subzero’s full portfolio of data center containment products, including aisle frames, doors, roofs, and airflow management systems. This unified approach enables Subzero to deliver turnkey containment solutions engineered for performance, safety, and long-term scalability—backed by a single partner and a coordinated system designed to work together.
