Dissolvable Air Barrier (DAB) Panels

ESSENTIAL DISSOLVABLE AIR BARRIER PANELS

Eliminate Trip Hazards While Maintaining Thermal Containment

Why Choose Subzero Engineering’s Dissolvable Air Barrier Panels?

DAB Panels are designed to meet fire code requirements in jurisdictions where traditional drop-out panels have been restricted by Authorities Having Jurisdiction. The proprietary cellulose-based construction dissolves completely in under 30 seconds when exposed to sprinkler water. This eliminates the trip hazards and obstructions that have raised concerns in Virginia, Texas, California, and other states.

As data center fire safety requirements evolve, maintaining thermal separation between hot and cold aisles while meeting code compliance has become increasingly complex. DAB Panels address these requirements by providing containment that works within existing fire suppression systems without creating the safety hazards associated with falling panels.

Key Features and Benefits

Fire Safety Compliance

The panels carry an ASTM E84 Class A fire rating with a flame spread index of 20 and smoke developed index of 0. The dissolvable design has been validated by independent fire protection engineers and is EPA Safe and CE Certified. The panels dissolve in under 30 seconds on water contact, eliminating trip hazards while maintaining sprinkler effectiveness.

• Thermal Performance:

  
  DAB Panels help optimize data center cooling efficiency and cooling equipment to operate more efficiently while still maintaining ITE ASHRAE thermal guidelines.

• Installation Flexibility:

  
  The panels are manufactured in standard 24″ x 24″ sizes that integrate with existing data center infrastructure. Multiple installation methods are available for both horizonal and vertical containment systems.

• Cost Effectiveness:

  
  Implementing DAB Panels can reduce fire suppression infrastructure costs through improved sprinkler coverage requirements. Many installations qualify for utility energy rebate programs, further improving project economics and project ROI.
