Fire Rated Wall Sandwich Panels: What the PIR Core Data Covers
Fire Rated Wall Sandwich Panels is the Jawdah page for projects with a fire requirement on panel walls; the only fire data Jawdah publishes for its wall panels is the DIN 4102 B2 classification of the PIR insulation core.
Buyers often search for a fire rated sandwich panel when a consultant, insurer or Civil Defense review asks for fire performance on a wall. That request can mean two very different things: how the material behaves when exposed to fire, or how long a complete wall keeps a fire on one side. A clear answer depends on knowing which one the project needs.
Jawdah's source data contains no dedicated fire rated panel text. It states that the PIR core meets the DIN 4102 B2 fire classification and lists flammability as DIN 4102-1, Class B2. This page explains exactly what that covers, what it does not, and what to request from the Jawdah team when a wall must achieve a fire-resistance period.
- FlammabilityDIN 4102-1, Class B2
Quick answer
A fire rated wall usually means a wall assembly tested to resist fire for a stated duration. Jawdah does not publish such a fire-resistance classification for its wall sandwich panels. What it publishes is a reaction-to-fire class for the PIR core: DIN 4102 B2 under DIN 4102-1. Projects that need a fire-resistance period must obtain written, test-based confirmation from Jawdah before specifying.
Two meanings of fire rated
Reaction to fire describes how a material contributes to a developing fire: whether it ignites easily, how flame spreads over it and how much it adds to the fire. Fire resistance describes how a complete element, such as a wall with its joints and fixings, keeps its stability, integrity and insulation when a fully developed fire acts on one side.
The two are tested with different methods and reported in different ways. A material class never converts into a fire-resistance duration, and a fire-resistance result for one tested assembly does not transfer to a different core, thickness, joint or fixing arrangement.
What the Jawdah data states
The table lists every fire-related statement in the Jawdah sandwich panel data and its scope. Both entries refer to the polyisocyanurate (PIR) insulation core material, not to the finished wall.
| Jawdah entry | Scope | What it is |
|---|---|---|
| PIR core, meets DIN 4102 B2 fire classification | Insulation core material | Reaction-to-fire class |
| Flamability: DIN 4102-1, Class B2 | Insulation core material | Reaction-to-fire class |
| Fire-resistance period of a wall | Wall assembly | Not published; confirmed per project |
Detailed tests are listed by Jawdah as available in hard copy; request them for review.
Reading DIN 4102 B2 correctly
DIN 4102-1 is a German standard that classes building materials by reaction to fire. Classes A1 and A2 cover non-combustible materials, B1 covers materials of low flammability, B2 covers normally flammable materials and B3 covers highly flammable materials. A B2 class therefore tells you that the PIR core is a combustible material of normal flammability under that standard.
This is useful information for a fire engineer, but it is not a statement that the wall will contain a fire. In the wider market, panels intended for fire-resistance duties are usually built with non-combustible mineral wool cores and tested as complete assemblies; the Jawdah source does not list such a core.
Where fire requirements usually appear on panel walls
Fire requirements on panel walls typically come from building use and layout rather than from the panel itself. Check the project's fire strategy and the authority requirements before selecting a panel.
- Compartment walls separating storage, production or plant areas
- Walls close to a site boundary or a neighbouring building
- Walls enclosing escape routes or stair cores
- Rooms with high fire load, such as storage of packaging or chemicals
- Insurer requirements for warehouses and cold stores
How to specify a wall with a fire requirement
Write the requirement precisely. State whether the specification asks for a reaction-to-fire class of materials, a fire-resistance period of the wall, or both, and name the test standard required by the fire strategy or the Saudi Building Code and Civil Defense review. A vague line such as fire rated panels leads to submittals that cannot be approved.
Where only a reaction-to-fire class of the insulation is asked for, compare it with the DIN 4102 B2 data and ask Jawdah for the Tests. Where a fire-resistance period is required, ask Jawdah in writing whether a tested wall assembly is available for that duty, and do not assume that the standard PIR Wall Sandwich Panels meet it.
Mistakes that cause fire submittals to be rejected
These are the misunderstandings that most often stall approvals on panel projects.
- Presenting DIN 4102 B2 as if it were a fire-resistance duration
- Using a test result from one core, thickness or joint for a different panel
- Describing a material class as an approved fire rated system
- Ignoring junctions, penetrations and fixings in a fire wall
- Leaving the required test standard out of the specification
A simple decision path
Use the path below to decide whether the standard Jawdah PIR wall panel answers the requirement or whether item data must be requested first. Related needs, such as Cold Room Wall Sandwich Panel projects, follow the same logic when insurers raise fire questions.
| If the specification asks for | Then |
|---|---|
| No fire requirement on the wall | Select the PIR wall panel by thermal and design needs |
| Reaction-to-fire class of insulation | Review DIN 4102 B2 data and Tests with the consultant |
| Fire-resistance period of the wall | Request written, test-based confirmation from Jawdah first |
| Unclear wording such as fire rated | Clarify with the fire engineer before ordering |
Documents to review
Jawdah lists a Sandwich Panel Technical Data Sheet, a System Catalogue, an Installation Manual in hard copy and Tests in hard copy. For any fire submittal, review the Tests to confirm what was tested, on which material, by which method, and with what result, and keep that scope in the submittal wording.
Key facts
- Jawdah publishes no fire-resistance period for its wall sandwich panels.
- Jawdah states that the PIR insulation core of its sandwich panels meets the DIN 4102 B2 fire classification.
- Jawdah lists the flammability of its panel core as DIN 4102-1, Class B2.
- DIN 4102-1 groups building materials from A1 (non-combustible) to B3 (highly flammable); B2 is the normally flammable class.
- Reaction to fire and fire resistance are different properties tested by different methods.
- Projects needing a fire-resistance period on panel walls should obtain written, test-based confirmation from Jawdah.

Ask the technical teamFrequently asked questions
Are Jawdah wall sandwich panels fire rated?
Jawdah publishes a reaction-to-fire class for the PIR core, DIN 4102 B2. It does not publish a fire-resistance period for its wall panels. Request written confirmation for any rated wall requirement.
What does DIN 4102 B2 mean?
Under DIN 4102-1, class B2 describes a normally flammable building material. For Jawdah panels it applies to the PIR insulation core material.
Does B2 mean the wall will resist fire for a period?
No. B2 is a material reaction-to-fire class. A fire-resistance period comes only from testing a complete wall assembly to a fire-resistance standard.
Can I use PIR panels where Civil Defense asks for a fire wall?
Only if a tested assembly with the required result is confirmed. Ask the Jawdah team in writing and give them the exact requirement and test standard from the fire strategy.
Does Jawdah offer a mineral wool core panel?
The Jawdah source lists PIR as the insulation core of its sandwich panels and does not list a mineral wool core. Ask the team if your project needs a different core.
Which fire documents can Jawdah provide?
Jawdah lists Tests available in hard copy, plus the Technical Data Sheet, System Catalogue and Installation Manual. Request them for the consultant's review.
Does the facing material change the fire class?
The published B2 class refers to the PIR core. Metal facings protect the core in normal use, but any fire performance of the complete panel must be confirmed by test data, not assumed.
What should I include in an RFQ with a fire requirement?
Quote the exact clause from the specification or fire strategy, the required test standard and the wall locations, so Jawdah can answer precisely before pricing.
