When evaluating fire-retardant treatments for timber, most specifiers focus on certification and fire class. But there is another metric that has a direct impact on project economics and logistics: consumption rate.
What is consumption rate?
Consumption rate refers to the amount of fire-retardant product required to treat one square metre of timber surface. It is typically measured in millilitres per square metre (ml/m²) or grams per square metre (g/m²).
For SPFR100, the typical consumption rate is 200–240 ml/m², depending on wood species, profile, and the target fire classification.
Why consumption rate matters
A lower consumption rate translates into tangible benefits:
- Lower material cost: Less product is needed per square metre, reducing the overall treatment cost.
- Easier logistics: Fewer containers need to be transported and stored, simplifying project planning.
- Faster application: Less material means shorter dipping or spraying cycles, increasing throughput on industrial lines.
- Environmental impact: Lower consumption reduces the carbon footprint of transportation and packaging.
SPFR100's advantage
Compared to many traditional fire-retardant systems, SPFR100 offers one of the lowest consumption rates on the market while still achieving B-s1,d0 classification. This makes it particularly attractive for large-scale projects where every millilitre counts.
For example, treating 1,000 m² of timber façade with SPFR100 at 220 ml/m² requires 220 litres. A competing product with a consumption rate of 350 ml/m² would need 350 litres for the same area – a 59% increase in material cost and logistics complexity.
The bigger picture
Consumption rate is not just a technical detail. It directly affects project budgets, timelines, and competitiveness. When combined with SPFR100's weather resistance and certified performance, the low consumption rate makes it a compelling choice for timber fire protection.
