AccelShell™

The new standard for insulated wall panels

AccelShell™ insulated wall panels can be customized to meet project-specific thermal performance and finish requirements, and can be load-bearing or cladding only, making them ideal for commercial buildings and data centers.

Manufactured at our offsite facility and delivered ready for installation, these panels help minimize site risk, reduce field impacts, and support faster project delivery.

Frequently Asked Questions

AccelShell™ is Clark Pacific’s prefabricated insulated wall panel and enclosure solution for data centers and other critical facilities. The system combines a durable precast concrete exterior, continuous insulation, interior concrete wythe, engineered connections, and coordinated joint detailing into a factory-produced wall assembly. AccelShell™ can serve as the exterior enclosure and, in select configurations, can also be engineered as part of the building’s structural system.

Owners choose AccelShell™ when they want a faster, more coordinated way to deliver the building enclosure. Instead of coordinating separate trades for framing, sheathing, insulation, exterior cladding, weather barrier, fire detailing, and finish work, AccelShell™ brings those functions into a prefabricated precast wall system. This helps accelerate dry-in, reduce field labor, improve quality control, and create a more durable exterior wall assembly.

AccelShell™ improves schedule by shifting major enclosure work into factory production while site work and structural activities advance. Panels can be engineered, detailed, fabricated, finished, and delivered in a planned sequence so the building enclosure can be installed quickly once the site is ready. Because insulation, exterior finish, embeds, openings, and connection details are coordinated before fabrication, AccelShell™ helps reduce delays from field layout, trade stacking, weather exposure, and late enclosure coordination.

AccelShell™ supports thermal performance by placing insulation inside the factory-built wall panel assembly and coordinating connectors, joints, sealants, flashings, and terminations as part of the complete enclosure system. AccelShell™ panels are intended to serve as the primary exterior wall and weather-barrier assembly when detailed and installed with the specified joint and flashing system. Additional membranes or alternate weather systems can be incorporated when required by the owner, design team, or project specifications.

Yes. AccelShell™ can be configured as a cladding wall system attached to a separate structural frame, or as a load-bearing wall system where the wall panels are engineered to carry vertical and lateral loads. Cladding applications focus on enclosure, insulation, durability, and exterior finish. Load-bearing applications integrate the wall panels into the structural system, helping reduce separate framing and support faster delivery. Final configuration is based on building design, loads, seismic requirements, connections, openings, and project-specific engineering.
