Fire performance is described in two ways. Reaction to fire shows how a material burns, for example Euroclass A1 for non-combustible products under EN 13501-1. Fire resistance shows how long a wall, door or ceiling assembly keeps its integrity and insulation, for example EI 60 or EI 120 under EN 13501-2, or hourly ratings under ASTM E119 and Chinese standards such as GB/T 9978. Your fire engineer and local code decide which is needed.
| Panel core | Reaction to fire | Typical notes |
|---|---|---|
| Rockwool (mineral wool) | Non-combustible, often Euroclass A1 or A2 | Best fire performance, heavier, needs sealed edges against moisture |
| Glass wool | Non-combustible in many forms | Lighter than rockwool, check panel build |
| Aluminum honeycomb | Metal, low fuel load | Light, good for ceilings, not an insulation fire barrier |
| PIR (polyisocyanurate) | Combustible but better than PU | Good insulation, may meet insurer tests in tested builds |
| PU (polyurethane) | Combustible | Good insulation, often limited by fire rules |
| EPS, paper honeycomb | Combustible | Economical, mostly for low-risk dry areas |
Assembly points that decide real performance:
- Joints and profiles: the rating depends on the tested profile, thickness and joint detail.
- Fixings and ceilings: the supporting structure and hangers must also resist fire.
- Doors and glass: a fire door is a certified assembly of leaf, frame, seals and hardware.
- Penetrations: ducts, cables and pipes through a rated wall need approved fire stopping and dampers.
Cleanroom panels often form non-load-bearing partitions inside a building. Where a fire compartment boundary is required, the project may use masonry or fire board walls with cleanroom panels as infill. We will tell you plainly what our panels can and cannot do.
Cross-Border Delivery and Localized Construction Support
The main challenge in an overseas fire-rated project is that local authorities accept only certain test standards and certificates. A rating tested to one standard may not be accepted in another country without review. We therefore discuss approval requirements at the start, before production.
- Code and standard check: we ask which standard and rating your authority requires.
- Document match: we compare it with the test reports that exist for our panels and doors.
- Drawings: wall, ceiling, door and joint details are agreed before production.
- Packing and shipping: flat-pack loading, with rockwool panels protected from moisture, and documents with FOB, CFR or CIF terms.
- Installation support: manuals, video guidance or a supervising engineer.
Local construction: fire performance depends on installation as much as on the product. The installer must follow the tested details, without changing fixings, joints or sealants. Penetrations for ducts, cables and pipes need approved fire stopping, which is usually handled by a local specialist.
Local fire inspectors may need to witness installation or review documents. We provide drawings, material data and available test reports, and your engineer or contractor remains responsible for the approval process.
We also suggest early contact between our engineer and your fire consultant or authority. A short call to review the wall layout, door positions, ceiling build and penetration plan often removes the doubts that otherwise appear at inspection, when changes are costly.
Staged shipments can be arranged when the building is handed over in phases.
We are glad to review your floor plan.
Quality Control and Certification
Fire safety is an area where claims must be exact. We state a fire rating only when a test report supports it for the specific panel build, door or glazing, and we do not extend a rating to other thicknesses, cores or joints. This protects you and your project.
| Control step | Inspection | Why it matters |
|---|---|---|
| Incoming materials | Core density and type, face sheet, adhesive, profiles | Matches the tested build |
| Panel production | Thickness, bonding, edge sealing, dimensions | Consistent assembly |
| Core verification | Check of core type against the order | Right fire performance |
| Door and glazing | Leaf, frame, seals, hardware as a complete set | Certified assembly integrity |
| Packing | Count, labels, moisture protection | Core stays dry and intact |
Documents available: material specifications, factory inspection records and, where available, fire test reports and classification documents for panels, doors and glazing. Please tell us the exact standard and rating your project needs.
If no matching report exists, we will say so, and we can discuss options, such as a different panel build, a compatible tested door, or a new test by an accredited laboratory at the project's cost. Plain communication on this point prevents rejection at inspection.
Consultants and authorities often ask for the full test report, not only a summary, so that they can check the tested thickness, joint and fixings against the project. We share the documents that exist and explain which details they cover. Our factory can host audits or live video tours, so reviewers can see how panels are made and inspected.
Batch records are kept for each project, so later questions about a particular wall or door can be traced to production.
After-Sales Service and Response Capability
A fire-rated system keeps its value only if it stays intact. Damaged panels, loose seals and added penetrations can reduce performance without being obvious. Our after-sales service focuses on helping you maintain the system as it was tested and installed.
- Fast communication: technical questions answered in English by email, phone or messaging.
- Remote diagnosis: photos or videos of damaged panels, door seals and joints help us advise on repair.
- Matching spare parts: panels, door leaves, seals, hinges, closers and glazing in the same build.
- Modification advice: before cutting a new opening, ask us how to do it without losing the rating.
- Engineer visits: by arrangement.
Typical points to check during inspections:
| Item | What to look for | Suggested action |
|---|---|---|
| Fire door | Door closes fully, seals intact, no damage | Adjust or replace parts with matching items |
| Panel joints | Gaps, damaged edges, wet core | Repair or replace panel |
| New penetrations | Unsealed cable or pipe openings | Fit approved fire stopping |
| Ceiling hangers | Loose or modified fixings | Restore to tested detail |
Please keep records of modifications, since fire authorities and insurers may ask for them. Do not drill or cut rated walls without approved details.
Fire-rated systems should be included in the building's regular inspection program. We suggest that your maintenance team checks doors, seals and visible joints every month, and that any new opening or repair is planned with us or your fire consultant first.
When a part must be replaced, send us the room name and a photo. We will check the original drawings, identify the panel or door type and prepare a matching part. For urgent cases, we discuss the fastest shipping option.
Spare seals, hinges and closers at the site help you act the same day.
Commercial Terms, Warranty and Lifecycle Cost
Fire-rated systems cost more than basic panels, but the cost of a fire, an insurance refusal or a failed inspection is far higher. A clear fire strategy at the start usually saves money, because it avoids redesign, rejected materials and delays.
| Item | Our approach |
|---|---|
| Quotation | Itemized by wall, ceiling and door type, with drawings |
| Trade terms | FOB, CFR or CIF, defined in the quotation |
| Payment | Commonly a deposit with balance before shipment or against documents; final terms in the contract |
| Warranty | Defined by component group in the contract |
| Lead time | Given after drawing confirmation; fire-rated items may need longer |
| Customization | Core type, thickness, face, door rating, glazing |
Where cost is decided:
- Rating level: a longer rating needs heavier cores, stronger frames and certified hardware.
- Core choice: rockwool costs more than EPS but gives non-combustible performance.
- Doors and glass: fire doors and fire-rated glazing are significant cost items.
- Approval: additional testing or inspection raises cost but may be required locally.
Sprinklers, alarms, smoke control, fire stopping, structural fire protection and permits are outside our supply. Warranty exclusions are stated clearly in the contract.
When comparing quotations, ask each supplier to state the core type and density, panel thickness, rating standard, test report reference, door rating and glazing. Differences in these items explain most price gaps and are the points inspectors check.
We provide itemized quotations and can show alternatives, such as rockwool in rated walls and economical panels in non-rated areas, so that your budget is used where code requires it.

Fire-Rated Cleanroom Walls FAQ
Q1. What is the difference between non-combustible and fire-resistant?
Non-combustible describes how a material burns. Fire-resistant describes how long a whole wall or door assembly keeps its integrity and insulation in a test.
Q2. Are rockwool panels fire-rated?
Rockwool is a non-combustible core, but a rating belongs to a tested panel build and joint system. Please tell us your required standard and duration.
Q3. Which standards are used?
Common ones include EN 13501-1 and EN 13501-2 in Europe, ASTM E119 and UL 263 in the United States, and GB/T 9978 in China. Insurers may also use their own tests.
Q4. Can PU or PIR panels be used?
They are combustible cores, though some tested builds meet insurer requirements. Your fire engineer decides whether they are acceptable.
Q5. Can I cut an opening in a rated wall?
Only with an approved detail and proper fire stopping. Please ask us first.
Q6. Do you supply fire doors?
We supply doors with fire performance where a matching test report exists. We will confirm the rating for your order.
Q7. How do I get a quotation?
Send your fire standard, required duration, drawings and destination country.
Q8. Do insurers have their own tests?
Some insurers use their own approval schemes for insulated panels. Please tell us if your insurer has requirements, and we will check what we can document.
Q9. Can fire performance be added to an existing room?
Only with a suitable assembly and approved details. Please ask us before changing walls.
