Firewall fire-retardant coatings with European classification are essential for ensuring the safety of buildings and structures in compliance with fire safety regulations. The choice of certified fire-retardant coatings is crucial for meeting the requirements of fire resistance and reaction applicable to many wooden structures in both public and private spaces.


When you consult our experts in fire-retardant and intumescent coatings, you are placing your trust in professionals with years of experience in the field, who are able to recommend the most advanced solutions that comply with European standards.


Our range of fire-retardant coatings with European certifications complies with the most stringent EU standards: Bs1-d0, Bs2-d0 and BFL-s1.

Fire-retardant coatings

Hospitals, schools, theatres, cinemas, auditoriums, exhibition centres, shopping malls, hotels, places of worship, stations, airports, historic and monumental sites

CLASSIFICATION

Bs1-d0

Bs1-d0 certification represents one of the highest levels of fire safety for building materials. It is in high demand for the treatment of wooden walls, claddings and ceilings. With extremely limited flame spread (Class B) and minimal smoke production (s1), this certification is required for high-risk buildings, where it is essential to ensure maximum protection and maintain visibility in the event of a fire, such as shopping malls and large public buildings.

CLASSIFICATION

Bs2-d0

Bs2-d0 certification confirms that the material treated with fire-retardant coating has low flame spread (Class B) and moderate smoke production (s2), with no flaming droplets (d0). Bs2-d0 certification is in high demand for the treatment of wooden walls, claddings and ceilings. This type of coating is particularly suitable for environments where it is essential to limit the spread of fire and reduce the risks associated with the formation of dense smoke, such as theatres, schools or hospitals.

CLASSIFICATION

BFL-s1

The BFL-s1 certification applies specifically to flooring materials. It certifies that the material treated with Firewall fire-retardant coatings is flame-resistant (Class BFL) and produces a minimal amount of smoke (s1) in the event of combustion. This certification is essential for ensuring safety in high-traffic environments, such as offices, hotels and commercial spaces, where safety and visibility during an evacuation are paramount.

Characteristics of Firewall fire-retardant coatings classified as European Fire Reaction classes Bs1d0 and Bs2d0​

Firewall fire-retardant coatings in Class 1 features:

  • They slow down the spread of flames. Firewall coating system has passed tests demonstrating that it drastically reduces the ability of fire to spread across the treated surface
  • Intumescent formula: some coatings in European Class are intumescent, which means that, when exposed to heat, they expand to form a protective insulating layer that slows down the combustion of the material beneath
  • Low smoke emission: as well as preventing the spread of flames, Firewall fire-retardant coatings in European Class ensure low emissions of toxic fumes, thereby improving safety during evacuation
  • Durability and stability: Firewall solutions are long-lasting and remain effective even long after the fire-retardant system has been applied
  • Advanced aesthetics: like all Renner Italia products, Firewall coatings offer design solutions with an infinite range of colour options (tinting system) and gloss levels.

Substrates that can be treated with European
classified fire-retardant coatings

SOLID WOOD

When used in furniture, wood is highly flammable and requires fire-retardant treatment to slow down combustion.

MDF or chipboard panels

Frequently used in furniture and interior finishes, they require effective protection to comply with safety regulations.

FABRICS AND CLADDINGS

Rugs, curtains and other textiles must be treated with fire-retardant coatings or treatments to prevent fires.

PLASTIC MATERIALS

Some polymers used in coatings and furnishings must be flame-retardant to prevent flames from spreading rapidly.

STEEL AND METAL

Although metals are non-combustible, they must be treated with fire-retardant coatings when used as furniture materials, as standard coatings are, by contrast, highly flammable
