What Makes an A2 Non-Combustible Cladding Panel Different?
The commercial term “nonflammable ACM panel” is useful for search, but professional procurement should use the fire classification and exact tested construction. In an A2-oriented aluminum composite panel, the core is engineered with a high mineral content rather than a conventional polyethylene-rich core, while aluminum cover sheets provide the finished faces and fabrication surface.
Do not confuse A2 with ordinary FR or B1 ACP
Fire-retardant ACP and A2 non-combustible ACP are not interchangeable purchasing descriptions. A B1/FR panel can use a flame-retardant mineral-modified core, while an A2-oriented construction generally requires a substantially higher inorganic/mineral content and must be evaluated under the specified fire test and classification route.
- Write the required classification and test standard into the RFQ.
- Ask for the exact panel build-up covered by the report.
- Match skin thickness and coating to the submitted sample and production order.
- Confirm whether the fire requirement applies to the panel only or the complete façade assembly.
- Have the architect, consultant or local authority confirm acceptance for the intended building.
A2 vs B1 / FR vs Standard PE Core: Compare Before You Quote
This comparison is intended to help buyers frame the RFQ. Local codes differ, and a panel name alone does not establish compliance.
| Panel Direction | Core Concept | Typical Buying Priority | What to Confirm |
|---|---|---|---|
| A2 target Non-combustible ACP / ACM | High mineral / inorganic core construction designed for stringent reaction-to-fire requirements. | High-rise façades, public buildings, transport facilities, healthcare, education and projects with strict fire specifications. | EN 13501-1 classification, exact test report, tested thickness and skins, coating, system requirements and local acceptance. |
| B1 / FR ACP | Mineral-modified flame-retardant core with improved fire behavior compared with standard PE core. | Projects where FR classification is specified but A2 is not required. | Exact FR grade, test method, core formulation, smoke / droplet criteria and destination requirements. |
| Standard PE ACP | Polyethylene-rich core. | Signage, selected interiors and other applications where the relevant code permits the proposed construction. | Application limitations, coating, thickness, skin gauge and local fire rules. |
Non-Combustible Aluminum Composite Panel Specifications to Confirm
DERACP can review the specification around the real project. The values below are practical purchasing references—not a statement that every combination carries the same A2 classification. Final availability and fire documentation must be tied to the approved construction.
| Specification Item | Project Direction | Buyer Confirmation |
|---|---|---|
| Total panel thickness | 4 mm is a common architectural reference; other constructions can be reviewed. | Use the thickness covered by the required fire report and compatible with the façade design. |
| Front / rear aluminum skin | Architectural A2 projects often discuss 0.50 mm skins; other gauges may be possible depending on the tested build. | State front and back skin thickness separately in the quotation and purchase order. |
| Core | A2-oriented high-mineral / inorganic core configuration. | Require the core description and matching classification evidence for the exact panel. |
| Coating | PVDF is commonly evaluated for exterior façades; FEVE or other systems may be considered by project. | Confirm resin system, color, gloss, coat build, exposure, warranty basis if applicable, and sample reference. |
| Width | 1220 mm, 1250 mm and 1500 mm are common ACP production references; custom widths are subject to review. | Check production limits, façade module, cutting yield, pallet size and report coverage. |
| Length | 2440 mm and longer project sheets can be discussed. | Balance joint reduction against handling, flatness, fabrication and container-loading constraints. |
| Finish | Solid, metallic and selected decorative effects; custom color matching can be discussed. | Approve a physical sample and record color code, gloss and directional effect where applicable. |
| Protective film | Standard or OEM-printed film according to order requirements. | Define film identity, direction, adhesion, storage conditions and removal timing. |
| Export packing | Panel stacks, edge protection, pallets or reinforced packing based on size and route. | Confirm bundle identification, sheet count, moisture protection, loading method and destination handling. |
A2 Non-Combustible Cladding for Fire-Sensitive Building Envelopes
Project teams often evaluate A2 aluminum composite material where the façade specification, building height, occupancy, authority requirement or risk assessment calls for a more stringent reaction-to-fire class than conventional ACP.
- High-rise and mid-rise exterior façades
- Hospitals, clinics and healthcare facilities
- Airports, metro stations and railway terminals
- Schools, universities and public buildings
- Shopping centers, hotels and office complexes
- Soffits, parapets, columns and curtain-wall infill areas
Match panel to the complete wall design
Coordinate skin gauge, cassette dimensions, routing, stiffeners, subframe, fixing details, cavity barriers and required assembly-level fire evidence.
Review evidence before material approval
Reference the exact classification, report number, panel build, coating and limitations in the submittal rather than accepting a generic “A2 ACP” statement.
Build a traceable A2 product program
Define repeatable sheet sizes, colors, skins, film, pallet identification and document sets so reorders remain aligned with the approved specification.
Compare equivalent construction, not price labels
A lower quote may describe a different core, aluminum gauge, coating or test scope. Normalize the technical specification before comparing commercial terms.
Plan routing and folding around the A2 core
Higher-mineral cores can process differently from PE-core ACP. Confirm tool selection, groove geometry, bending radius and dust management through trials.
Separate branding from compliance identity
Custom film and packaging can carry your brand, but test documentation and product identification must remain traceable to the actual tested construction.
Seven Checks Before Buying a Non Combustible ACP Panel
A strong RFQ reduces the risk of receiving a sample, report and production batch that describe different constructions.
Name the standard
State “EN 13501-1 A2-s1,d0” or the project’s required local standard rather than writing only “fireproof ACP.”
Lock the panel build
List total thickness, front skin, rear skin, core and coating in one controlled specification.
Check report identity
Confirm the test report applies to the same product family and construction being proposed for supply.
Review façade system scope
Determine whether the project requires panel-level classification only or evidence for the complete installed wall assembly.
Approve color physically
Use an identified sample for color, gloss and metallic direction; screen colors should not be the final acceptance reference.
Trial fabrication
Before mass conversion, test cutting, grooving, bending, edge finishing and fixing details on the proposed A2 core construction.
Preserve traceability
Keep approved sample IDs, order specification, batch marks, packing labels and reports connected through delivery.

Non-Combustible Aluminum Composite Panel FAQ
What is a non-combustible aluminum composite panel?
It is an aluminum composite material developed for projects that require more stringent fire behavior than conventional PE-core ACP. In A2-oriented construction, two aluminum skins are bonded around a high-mineral / inorganic core. The term “non-combustible” should be supported by the specified classification and a report covering the exact product construction.
What does A2-s1,d0 mean for an ACM panel?
Under EN 13501-1, A2-s1,d0 is a reaction-to-fire classification. “A2” indicates very limited contribution to fire, “s1” relates to low smoke production, and “d0” indicates no flaming droplets / particles within the classification criteria. Always confirm the current standard edition, test report and project acceptance requirement.
Is A2 ACP the same as B1 fire-resistant ACP?
No. A2 and B1 are different classifications and may use different core constructions and test routes. A generic “fireproof ACP” description is not enough. State the required grade and standard in the RFQ and ask the supplier to match the proposed panel to the applicable report.
What thickness is common for A2 non-combustible cladding?
Four millimeters is a common architectural reference for A2 aluminum composite panels, and 0.50 mm aluminum skins are frequently specified in façade-grade constructions. However, the correct thickness and skin gauge must follow the façade design, required fire documentation and the exact tested panel build.
Can a nonflammable ACM panel use PVDF coating?
PVDF coating is commonly evaluated for exterior aluminum composite cladding because of its weathering and color-retention performance. Coating selection should match climate, exposure, color, cleaning and the construction covered by the required technical documentation.
Can DERACP supply custom colors and sizes for A2 cladding projects?
DERACP supports project-based customization of ACP dimensions, aluminum skins, coating, finish, protective film and packing. For an A2 requirement, custom variables must also be checked against the exact construction and test evidence required by the project before the order is approved.
What should I send to DERACP for an A2 ACP quotation?
Send the project country, application, required fire classification / standard, panel thickness, front and rear skin gauges, coating, color, width, length, quantity, façade or fabrication drawings, destination port, packing requirement and any consultant clause or report format requirement. If some values are undecided, identify them as open items rather than allowing assumptions.
Does an A2 panel automatically make the whole façade compliant?
Not necessarily. Building regulations can apply to the complete wall assembly, including insulation, cavity barriers, subframe, membranes, fixings and installation details. The architect, fire engineer, consultant and local authority should confirm the system-level requirements for the project.
Request a Specification-Based A2 ACP Review
Tell DERACP the required fire classification, panel build, façade application, color, dimensions, quantity and destination. Ask for the current technical documentation that matches the exact proposed construction before you compare price.
Technical note: product availability, test reports, classification, dimensions, tolerances, coating, lead time and regulatory acceptance are subject to the exact confirmed construction, current documentation and project requirements. DERACP product information does not replace review by the project architect, façade engineer, fire consultant or local authority having jurisdiction.
