About Multiwall Polycarbonate

Multiwall polycarbonate, including twinwall polycarbonate, is lightweight, impact-resistant plastic sheet with hollow channels between its layers. This structure provides thermal insulation and light transmission for data center aisle containment, industrial partitions, and glazing.

Curbell Plastics supplies multiwall polycarbonate sheet for hot aisle containment (HAC), cold aisle containment (CAC), and other industrial applications. Our team can help you compare sheet constructions, thicknesses, colors, and product-specific performance requirements.

Availability or tolerance note beneath the module: Sheet sizes, thicknesses, colors, and wall structures vary by brand and product. Contact Curbell Plastics for availability, dimensional tolerances, and custom size requirements.

Multiwall Polycarbonate Properties and Material Options

Compare product lines and sheet constructions for your application. Wall structure, thickness, and color affect panel weight, rigidity, thermal insulation, and light transmission.

Polygal® Multiwall / Twinwall is polycarbonate sheet available in double- and triple-layered constructions, with a range of colors and light-transmission options. Its lightweight, insulating structure makes it useful for data center hot aisle containment (HAC), cold aisle containment (CAC), industrial partitions, and glazing. Polygal® is also rated for low flammability under the International Building Code.

PoliCarb® is structural multiwall polycarbonate sheet available in a range of thicknesses, colors, and light-transmission options, with constructions that include parallel partitions and inclined cross walls. Its lightweight, insulating structure makes it useful for data center hot aisle containment (HAC), cold aisle containment (CAC), industrial partitions, glazing, and daylighting. UV protection is provided on the exterior-facing side, with protection on both sides available upon request.

Multiwall polycarbonate is useful when low panel weight, insulation, and light transmission are priorities. For doors or viewing panels that require a clear view of equipment, consider solid polycarbonate. Compare sheet construction, thickness, and support requirements when selecting material for your application.

Selecting Multiwall Polycarbonate for HAC and CAC Systems

Data center containment systems separate cold supply air from hot server exhaust to reduce air mixing and support efficient cooling. Twinwall and multiwall polycarbonate can form lightweight walls, overhead panels, and end-of-aisle barriers within these systems.

Hot aisle containment (HAC) encloses the hot exhaust aisle and directs return air toward the cooling system. Cold aisle containment (CAC) encloses the cold supply aisle to direct conditioned air toward server intakes.

Compare sheet construction, thickness, panel dimensions, framing, service temperatures, and support spacing when selecting containment panels. Effective containment also depends on panel joints, doors, and openings around cables and equipment.

For fire-performance requirements, confirm the classification and test documentation for the specified product, thickness, and color. Cooling performance depends on the facility’s airflow design and controls, as well as the complete containment system.

Additional Technical Guidance

Multiwall polycarbonate can be cut and drilled to fit panel layouts and framing systems. Fabrication should account for flute direction, thermal expansion, edge support, and the sheet’s internal structure. Cutting can leave chips or dust inside the hollow channels. Follow the fabrication guide (link to Polygal® Multiwall Fabrication Guide) for flute cleaning, end treatments, compatible profiles and sealants, and minimum bend radii.
