Fire Retardant Timber

Fire retardant timber delivers the natural beauty and structural benefits of timber while reducing fire risk. For construction projects where safety compliance is required, fire-treated timber provides documented protection that meets building regulations without compromising on aesthetics.

HALT NFR provides CE certified fire retardant wood for both internal and external applications. All orders are treated and supplied from our facility in Belfast, with delivery across the UK and Ireland.

Our Fire Retardant Timber Products

HALT NFR supplies a range of pre-treated timber products with fully documented and certified fire retardant properties, ready for specification across a variety of project types.

Sheet Materials

Fire retardant sheet materials offer the same protective properties in plywood and other engineered boards. These panels are well suited for wall linings, doors, furniture, and decorative applications, and can be finished using standard methods including painting and veneering.

TGV Timber

TGV timber is one of the most popular cladding profiles in the UK, offering a seamless appearance with additional strength and insulation. The interlocking tongue and groove design creates clean, continuous lines while the characteristic V-joint adds subtle shadow detail that brings visual depth to any facade.

HALT NFR supplies pre-treated TGV timber that combines aesthetic appeal with certified safety compliance. Each board is impregnated with BURNBLOCK®, a non-toxic, water-based fire retardant made from natural ingredients. The vacuum pressure treatment drives the solution deep into the timber, achieving a Euroclass B-s1,d0 rating under EN 13501-1 and full compliance with Construction Products Regulations.

Reclaimed Timber

Reclaimed timber combines sustainability with distinctive character, making it a popular choice for architects and designers focused on responsible building practices. By repurposing existing wood, reclaimed timber reduces landfill waste and lowers demand for virgin materials, supporting efforts to minimise deforestation.

HALT NFR supplies a diverse range of reclaimed timber products valued for their unique patina, natural durability, and long-lasting strength. These materials are ideal for flooring, wall cladding, architectural features, and interior design elements where authentic character and industrial aesthetics are desired.

What Is Fire Retardant Timber?

Fire retardant timber is timber that has been specially treated to resist ignition and slow the spread of flame. Through fire retardant treatment for timber, BURNBLOCK® is driven deep into the timber's cellular structure using vacuum pressure impregnation, creating fire-resistant material that performs far more effectively than untreated alternatives.

The treatment is completely invisible and leaves no residue or staining, so your timber is ready for finishing, coating, or painting without limitation.

How Does Fire Rated Timber Work?

When exposed to heat, the treated surface chars and releases water, absorbing thermal energy and preventing oxygen from reaching the timber. Without oxygen, there is no fire. The timber still chars, but does so in a controlled manner rather than contributing to flame spread as untreated timber would. This provides valuable extra time for safe evacuation should a fire break out, along with reduced damage to the building.

Fire Resistant Timber Classifications

Fire-treated timber is classified according to performance standards that determine its suitability for different applications. In the UK and Europe, the EN 13501-1 standard applies, with Euroclass B-s1,d0 representing a high level of fire performance.

What Does Euroclass B-s1,d0 Mean?

This classification indicates limited contribution to fire spread (B), minimal smoke production (s1), and no flaming droplets (d0). Timber treated with BURNBLOCK® by HALT achieves this rating, ensuring full compliance with the Construction Products Regulations (CPR) and providing the documentation you need for building control approval.

Applications for Fire Retardant Timber

Fireproof wood suits both internal and external applications across a wide range of building types and construction elements, including facade and wall cladding, decking, flooring, doors, and architectural features.

Commercial and Public Buildings

Hotels, schools, hospitals, care homes, restaurants, and retail spaces all benefit from fireproof timber that meets strict regulatory requirements while maintaining design flexibility. These environments demand materials that perform reliably under regulatory scrutiny, and treated timber allows architects to specify natural materials without compromising on safety.

External Cladding

Fire retardant timber provides an attractive facade finish while meeting stringent fire safety requirements. This is particularly valuable in urban environments where fire spread between buildings poses a genuine concern. With certified fire retardant timber, external cladding projects can achieve both visual impact and documented compliance.
