Paged|Fire Retardant Plywood

Frequently Asked Questions

Everything you need to know about fire retardant plywood specifications, applications, certifications and ordering.

Certification

+What certifications do Paged FR products carry?

Paged FR products are CE-marked under EN 13986 (wood-based panels in construction) using AVCP System 1 attestation - the highest verification level, requiring a Notified Body to conduct initial type testing, factory production control inspection and ongoing surveillance. Reaction-to-fire is classified under EN 13501-1; railway grades carry EN 45545-2 certificates issued by accredited European laboratories. All wood is sourced under FSC and PEFC chain-of-custody certifications.

+FSC vs PEFC - which one do I need?

Both are credible international forest certification schemes. FSC (Forest Stewardship Council) is more frequently specified by international architects and accepted by all major green building schemes (BREEAM, LEED, DGNB). PEFC (Programme for the Endorsement of Forest Certification) is widely accepted in mainland Europe and is often required in public procurement. Paged sources wood under both schemes; specify your preferred chain-of-custody at the order stage so the matching documentation is issued.

+Where can I download the Technical Data Sheet (TDS)?

Each product page on this site has a 'Documents' section with the TDS, Declaration of Performance (DoP), CE certificate and fire classification reports as downloadable PDFs in English (and Polish, German, French where available). Documents are kept in sync with the latest test reports.

+What is the formaldehyde emission class?

Paged FR products are classified E1 (EN 717-1, less than 0.124 mg/m^3 in chamber test), the standard EU class for indoor wood-based panels. Selected lines are also available in lower-emission grades on request. All adhesives are phenol-formaldehyde-based, which is among the most stable and least-emitting formaldehyde resin systems used in plywood manufacturing.

Fire Classification

+What does B-s1,d0 mean?

B-s1,d0 is a notation under EN 13501-1: 'B' indicates the highest practical reaction-to-fire class for a combustible material (very limited fire contribution); 's1' is the lowest smoke production category; 'd0' indicates no flaming droplets are released during testing. Together these are the strictest sub-classes available for class-B materials and represent the standard fire performance target for fire retardant plywood used in public buildings, transport hubs and regulated occupancies.

+Which standards apply to railway interior plywood?

The European harmonized standard for railway interior fire performance is EN 45545-2. It assigns each material a Hazard Level (HL1, HL2 or HL3) and a Requirement Set (R1 for walls/ceilings, R10 for floors, R7 for cables, etc.). Fire retardant plywood used in passenger rail interiors typically targets HL2 or HL3 in groups R1, R6, R7, R10 or R17. The standard supersedes earlier national standards such as DIN 5510-2 (Germany), BS 6853 (UK), NF F 16-101 (France) and UNI CEI 11170-3 (Italy).

+Which standards apply to plywood in road vehicles?

In the EU, plywood used in the interior of buses and coaches with more than 22 passenger seats (M3 category) must meet UN ECE R118. The regulation tests horizontal burn rate (Annex 6), melting behaviour (Annex 7) and vertical burn rate (Annex 8). For trucks, vans and trailers there is no harmonized fire requirement at vehicle level, but customers in cold-chain and dangerous-goods transport often specify EN 13501-1 Class B materials by contract.

Logistics & Lead Times

+What is the lead time for full-truck quantities?

Standard formats and most popular thicknesses are typically available from stock with delivery in 3-10 working days within EU. Custom thicknesses, sizes or large project volumes are scheduled into our production plan with lead times of 4-8 weeks depending on the product line and current order book. Contact our sales team for an accurate confirmation against your specification and delivery date.

+What is the minimum order quantity?

We supply from single-pallet quantities up to multi-truck project volumes. Minimum order varies by product and finish: stocked items can be ordered by the pallet; custom-treated, custom-finished or special-format orders typically require a minimum of one full pallet per specification. Get in touch for an exact quote.

+Do you ship outside the EU?

Yes. Our standard delivery area is the EU, EFTA and the United Kingdom; we also export to selected markets in the Middle East, North Africa and Asia. Export deliveries are quoted ex-works (EXW) or FCA Incoterms; we can support with documentation including phytosanitary certificates and customs paperwork for non-EU destinations.

Products

+What is fire retardant plywood?

Fire retardant (FR) plywood is conventional plywood treated with fire retardant chemistry to slow flame spread, reduce smoke and limit heat release in case of fire. Paged FR products achieve Euroclass B-s1,d0 (EN 13501-1) - the highest practical class for combustible building materials. The treatment is applied either by full vacuum-pressure impregnation (every veneer protected) or by surface impregnation, depending on the product line.

+How does FR plywood differ from regular plywood?

FR plywood looks and machines like regular plywood but contains fire retardant chemistry that reduces flammability. Mechanical properties (strength, stiffness, density) are largely preserved, especially with surface-impregnated grades. The key differences are: documented fire classification under EN 13501-1, EN 45545-2 or UN ECE R118; CE marking under EN 13986; and a higher unit cost reflecting the chemistry, the impregnation process and third-party certification.

+What thicknesses are available?

Standard Paged FR thicknesses range from 4 mm (thin liner panels) up to 40 mm (heavy structural floors). Each product specifies its own thickness range; please refer to the product page or download the Technical Data Sheet for the exact list. Custom thicknesses for project quantities can be quoted on request.

+What standard panel sizes do you produce?

Common production sizes are 1250 x 2500 mm and 1500 x 3000 mm. Some products are also available in 1220 x 2440 mm for export markets. Larger formats and cut-to-size are available for project quantities. Confirm exact dimensions on the product Technical Data Sheet.

+Is fire retardant plywood waterproof?

Standard fire retardant plywood is bonded with phenolic resin (gluing class 3 / EN 314) and resists moisture during installation and short-term exposure, but the fire retardant chemistry can be leached by prolonged rain contact. For applications with sustained moisture exposure, specify Paged DryGuard FR - a multi-layer panel that combines fire retardancy with hydrophobic coatings, fire-retardant adhesive and UV protection.

Sustainability

+Are the fire retardant chemicals safe for indoor use?

The fire retardant chemistry used in Paged FR products is based on nitrogen and phosphorus salts and is free of halogens (no bromine, no chlorine), heavy metals and PFAS. The chemistry meets EU REACH requirements and is designed for indoor use including hospitals, schools and public transport vehicles. Material Safety Data Sheets are available on request.

+Where does the wood come from?

All wood used in Paged plywood is sourced from sustainably managed forests in the Baltic region (Poland, Estonia, Latvia, Lithuania), under FSC and/or PEFC chain-of-custody certification. The Group operates two plywood mills in Poland (Moroccg WS1, WS2 and Pisz) plus a birch veneer mill in Parnu, Estonia (Paged Eesti).

Technology & Processing

+What is the difference between vacuum-pressure and surface impregnation?

Vacuum-pressure impregnation places the panel in an autoclave, evacuates air and forces fire retardant chemistry into every veneer. The result is full cross-section protection: even after cutting or drilling, the exposed wood remains fire-classified. Surface impregnation applies the chemistry to the outer veneers only - it preserves the substrate's original mechanical performance and is the right choice when machining will not penetrate beyond the impregnated layer. Both methods can achieve B-s1,d0; the choice depends on the application's machining and exposure profile.

+Does fire retardant treatment affect machinability?

Paged FR plywood can be sawn, drilled, routed (CNC), planed and sanded with conventional carbide tooling. Vacuum-pressure impregnated grades are slightly more abrasive on cutting edges due to crystallised salts; carbide-tipped or diamond tooling is recommended for production runs. Surface-impregnated grades machine like untreated plywood. Edges, cut-outs and through-holes do not need to be re-treated when the panel is fully impregnated.

+Can fire retardant plywood be CNC-routed?

Yes. Fire retardant plywood is regularly used for CNC-routed components in trains, buses, exhibition stands and architectural panels. Use carbide or diamond-tipped tooling, moderate feed rates and effective dust extraction. Edge profiles and pockets retain fire performance for fully impregnated grades; for surface-impregnated grades, deep cut-outs may require edge re-coating.

+Can FR plywood be used outdoors?

Conventional fire retardant plywood is not weatherproof on its own - the fire retardant salts can be leached out by rain. For exterior or moisture-exposed applications use Paged DryGuard FR, which combines fire retardancy with hydrophobic coatings, fire-retardant adhesive and UV protection in a multi-layer system that retains both fire and weather performance.

+How long is the fire retardant treatment effective?

For interior applications kept in service classes 1 and 2 (heated buildings, covered exterior), the fire retardant chemistry remains effective for the lifetime of the panel - it is bound within the wood matrix and does not migrate. Repeated wetting by rain or condensation can leach salts from conventional FR panels; for those conditions choose multi-layer protected products such as DryGuard FR or specify a protective finish.

+Does machining (drilling, cutting) compromise fire performance?

For vacuum-pressure (fully impregnated) grades the answer is no - the entire cross-section is protected, so cut edges, holes and pockets retain the certified class. For surface-impregnated grades, deep cut-outs may expose untreated wood; in such cases re-coat the cut surfaces or specify a fully impregnated product. Always check the product Technical Data Sheet for guidance.
