Technology that protects and lasts

SPFR100 uses advanced polymerisation technology that locks the active ingredients inside the wood, helping them stay effective even in demanding outdoor conditions.

Deep penetration

The formulation penetrates into the wood fibres instead of forming a thick film, reducing cracking and peeling over time.

Low maintenance

When applied according to instructions, SPFR100 offers long-term fire performance with minimal maintenance requirements.

Compatible systems

Works with many industrial coating lines, spray booths and dipping tanks. Our technical team can support you during trials.

Trusted certification

Tested and certified by independent laboratories to meet European fire-safety standards for wood products.

Consumption rate
200–240 ml/m²

One of the lowest consumption rates among fire-retardant treatments for wood, helping you cover more square metres per litre.

Fire reaction
B-s1, d0

Certified fire reaction classification according to EN 13501-1 when used as part of a documented SPFR100 timber system.

Package sizes
5L–1000L

From small canisters for detail work to 1000L IBC containers for industrial treatment lines and large façade projects.

Frequently Asked Questions

Common questions about SPFR100, fire performance, application and ordering.

Reaction to fire describes how a material behaves in the early stages of a fire (ignition, flame spread, smoke). SPFR100 improves this performance and can help achieve B-s1,d0 classification. Fire resistance, however, refers to how long a full structure maintains its load-bearing capacity during a fire. These are two separate concepts.

Yes. SPFR100 uses advanced polymerisation technology that gives the product genuine weather resistance, including leaching resistance. No extra lacquers are required when applied according to the instructions.

Typical consumption is 200–240 ml/m² depending on wood species and fire class requirements. This makes SPFR100 one of the most economical fire-retardants available today.

Yes. SPFR100 can be tinted to a wide range of architectural tones, including custom matching based on RAL, NCS and other colour charts. The colour is part of the fire-retardant treatment.

SPFR100 is suitable for façades, CLT, glulam, plywood, multilayer panels, interior decorative panels, structural timber and more. It can be used both indoors and outdoors.

Yes. Many building regulations require fire reaction classifications such as B-s1,d0 for wood surfaces. Using SPFR100 as part of a documented system helps ensure compliance and simplify approval processes.
