Fire Resistant Sandwich Panel Solutions
Fire resistant sandwich panel solutions from Real Panel provide a complete spectrum of fire safety performance for building envelopes — from Euroclass B-s2 (limited combustibility) through B-s1 (very low smoke) to A1/A2 (non-combustible). Whether your project requires enhanced fire protection for an industrial building, non-combustible cladding for a multi-story commercial facility, or fire-rated partitions within a cold storage complex, our fire resistant sandwich panel range delivers certified, tested, and documented fire performance across Turkey, Romania, Bulgaria, Georgia, Macedonia, and Kosovo.Fire safety in building cladding has never been more important. High-profile facade fires worldwide have tightened regulations, increased insurance scrutiny, and raised public awareness of building envelope fire performance. Specifying the right fire resistant sandwich panel is not just a code compliance exercise — it is a fundamental responsibility to the building's occupants, neighboring properties, and emergency responders.
Meeting Romania's Evolving Fire Safety Standards
Romania’s fire safety regulations have been tightening since the tragic 2015 Colectiv nightclub fire in Bucharest, which transformed public and regulatory attitudes toward fire safety in buildings. Romanian fire regulations (ISU requirements) now mandate specific fire resistant sandwich panel classifications for commercial, public, and multi-story buildings. PIR and rockwool panels are increasingly specified by Romanian architects and fire engineers for projects where B-s1 or A-class ratings are required.
Real Panel’s fire resistant sandwich panel solutions for the Romanian market include full EN 13501-1 fire test documentation, CE marking, and technical support for fire code compliance. Our panels travel from Turkey via Bulgaria within 7–10 working days, with fire test reports accompanying every shipment for building inspection purposes.

Why Fire Resistant Sandwich Panels? 5 Critical Advantages
Fire resistant sandwich panel construction is governed by the European fire classification system defined in EN 13501-1, which rates building materials from A1 (non-combustible) to F (no performance determined). Every Real Panel product carries a tested and certified Euroclass fire rating, giving designers, building officials, and insurers the documented fire performance data they need to approve your project.
- Certified Fire Performance — Tested, Not Assumed
Every fire resistant sandwich panel in our range has been tested to EN 13501-1 by accredited laboratories. Fire test reports document reaction-to-fire classification, smoke production (s-class), and flaming droplet behavior (d-class). This is not theoretical performance — it is measured, certified, and available for your building permit application.
- Complete Fire Spectrum — One Supplier, Every Rating
Real Panel is one of the few manufacturers offering fire resistant sandwich panel solutions across the entire Euroclass spectrum: PUR (B-s2, d0), PIR (B-s1, d0), rockwool (A1 or A2-s1, d0), and fibercement-PIR (A2-s1, d0). This means you can source every fire rating your project needs from a single supplier, with guaranteed compatibility and coordinated delivery.
- Very Low Smoke — The Hidden Lifesaver
In most building fires, smoke kills more people than flames. The s-classification in the Euroclass system rates smoke production: s1 (very low), s2 (low), s3 (moderate/high). Our fire resistant sandwich panel options at B-s1 (PIR) and A2-s1 (rockwool, fibercement) produce minimal smoke during fire exposure, giving occupants more time to evacuate and firefighters better visibility for rescue operations.
- Zero Flaming Droplets — No Fire Spread Downward
The d-classification rates whether burning material drops or falls from the cladding during fire. All Real Panel fire resistant sandwich panel products achieve d0 — no flaming droplets. This prevents fire from spreading downward to lower floors, adjacent materials, or evacuation routes below the facade.
- Self-Charring Protection (PIR)
Our PIR panels feature a unique self-charring mechanism: when exposed to fire, the PIR foam surface forms a dense carbon char layer that insulates the unburned material behind it. This self-limiting fire behavior slows fire penetration through the fire resistant sandwich panel, buying time for evacuation and emergency response.
Understanding the Euroclass Fire Classification System
The Euroclass system (EN 13501-1) classifies building materials by three criteria. Understanding this system is essential for specifying fire resistant sandwich panel solutions correctly:
Reaction to Fire (Main Class)
| Class | Meaning | Our Panel | Behavior |
| A1 | Non-combustible | Rockwool | Will not burn under any conditions |
| A2 | Very limited combustibility | Rockwool, Fibercement | Negligible contribution to fire |
| B | Limited combustibility | PIR (B-s1), PUR (B-s2) | Limited fire contribution, self-extinguishing |
| C | Moderate combustibility | — | Not in our range |
| D | High combustibility | — | Not in our range |
| E | Combustible (ignitable) | EPS | Burns but self-extinguishes when flame removed |
| F | No performance | — | Not in our range |
Smoke Production (s-class)
- s1 — Very low smoke: PIR, rockwool, fibercement. Visibility maintained for longer during fire. Best for occupied buildings.
- s2 — Low smoke: Acceptable for most industrial applications. Moderate smoke production.
- s3 — Moderate/high smoke: Not applicable to our fire resistant sandwich panel range.
Flaming Droplets (d-class)
- d0 — No flaming droplets: All Real Panel products. No burning material falls from the panel during fire.
- d1 — Limited droplets: Not applicable to our range — all products exceed this.
- d2 — Significant droplets: Not applicable.
Our Fire Resistant Panel Range — From B-s2 to A1
Our complete fire resistant sandwich panel product line, ranked by fire performance:
Rockwool Panels — A1 / A2-s1, d0 (Non-Combustible)
The ultimate fire resistant sandwich panel. Stone wool core does not burn at temperatures exceeding 1000°C. Zero smoke, zero droplets, zero fire contribution. Available for facades and roofs. Achieves BROOF(t1) external fire exposure rating for roofing applications. The heaviest panel option but the only truly non-combustible choice.
Fibercement Panels — A2-s1, d0 (Architectural + Fire-Safe)
Non-combustible fibercement exterior surface combined with PIR core. Our fibercement facade panels achieve A2-s1, d0 while delivering flat, architectural aesthetics that rockwool’s metallic surfaces cannot match. The premium fire resistant sandwich panel choice for commercial facades where both fire performance and appearance matter.
PIR Panels — B-s1, d0 (Fire-Enhanced Foam)
The highest fire rating achievable with a foam-core panel. PIR facade, PIR roof, and PIR cold room panels produce very low smoke (s1) and self-char to limit fire spread. The practical fire resistant sandwich panel choice for projects that need enhanced fire performance without the weight and cost of rockwool.
PUR Panels — B-s2, d0 (Standard Fire Performance)
Our PUR panels achieve Euroclass B-s2, d0 — limited combustibility with low smoke. Suitable for most industrial buildings, warehouses, and agricultural facilities where B-class fire performance is sufficient. The most cost-effective fire resistant sandwich panel option that exceeds the minimum B classification.
Fire Strategy by Building Type
Different building types have different fire resistant sandwich panel requirements. Here is a specification guide:
| Building Type | Min. Class | Recommended Panel | Rationale |
| Single-story industrial | B-s2 | PUR | Cost-effective, meets minimum code |
| Multi-story commercial | B-s1 | PIR or Rockwool | Stricter codes for height + occupancy |
| Schools & hospitals | A2 / B-s1 | Rockwool or Fibercement | Public safety, non-combustible preferred |
| Shopping centers | B-s1 | PIR (walls), Rockwool (boundary) | High occupancy + property boundary risk |
| Cold storage (ammonia) | B-s1 | PIR cold room | Ammonia fire risk, smoke critical |
| Property boundary walls | A2 | Rockwool | Prevent fire spread to neighbors |
| High-value asset storage | A2 / B-s1 | Rockwool or PIR | Protect contents + insurance |
| Agricultural buildings | E / B-s2 | EPS or PUR | Lower occupancy, budget priority |

Insurance & Regulatory Benefits
Specifying the right fire resistant sandwich panel directly impacts insurance costs and regulatory approvals:
- Lower insurance premiums: Upgrading from PUR (B-s2) to PIR (B-s1) on walls and roofs can reduce annual property insurance premiums by 5–15%. Rockwool (A1/A2) may qualify for further reductions. Over a building’s lifetime, premium savings can exceed the additional panel cost.
- Faster building permits: Fire resistant sandwich panel products with EN 13501-1 test reports and CE marking streamline fire code review in building permit applications. Documented fire performance eliminates the back-and-forth that uncertified materials cause.
- Post-Grenfell regulations: Several countries have tightened cladding fire regulations following the 2017 Grenfell Tower tragedy. Specifying A-class or B-s1 fire resistant sandwich panel materials ensures compliance with both current and anticipated future regulations.
- Mixed-panel fire strategy: Building codes often allow different fire ratings on different elevations — A-class on boundary walls, B-s1 on public facades, B-s2 on industrial rear elevations. Our single-supplier range makes mixed-panel fire strategies simple to specify and deliver.
