Questions and Answers
Why Choose Fire-Retardant Wood?
Fire-retardant wood makes it possible to combine wood’s natural and aesthetic qualities with the fire safety requirements of today’s construction projects. Through a documented and verified fire-retardant treatment, wood can be used in applications where untreated wood does not meet current fire safety requirements.
For the building owner, this means greater freedom in material selection, while the project’s fire performance can be verified through testing, classification, and associated documentation. This creates better conditions for meeting the project’s requirements without compromising on architecture, function, or sustainability.
Furthermore, when fire-retardant wood is certified and verified for its intended use environment—for example, through a documented use class where required—it provides a more reliable foundation for both the construction phase and long-term management.
Fire-retardant wood is not just about meeting a fire code requirement—it’s about creating the conditions for safe, sustainable, and long-term wood construction.
How do I know that the solution meets regulatory requirements?
To demonstrate that a solution meets the project’s requirements, it must be documented and verified in accordance with relevant standards, classifications, and applicable building codes. The documentation must also be relevant to the specific product, the structure, and the environment in which it will be used.
For wood facades, it is not always sufficient for an individual product to have a fire class. It is also important to ensure that the intended structure is covered by the documentation, tests, and any approvals that form the basis of the solution.
Reviewing the documentation as early as the design phase creates better conditions for an efficient construction project, reducing the risk of additional work, delays, and questions during technical consultations, inspections, and final approval.
A well-documented solution provides a more reliable foundation for design, the regulatory approval process, and long-term management.
Are two products with the same fire rating always equivalent?
No. Two products may achieve the same fire class, but still differ in terms of documentation, verified scope of use, durability, and the types of structures for which they have been tested and classified.
When selecting a fire protection solution, it is therefore important to evaluate the entire technical documentation—not just the declared fire resistance class. Factors such as the product’s Field of Application (FoA), verified use class where applicable, system testing, and third-party-monitored manufacturing can have a significant impact on how the solution is intended to be used and verified.
A well-documented solution provides a better basis for decision-making and greater peace of mind throughout the entire construction process—from design and construction to facility management.

Woodsafe’s strength lies in the combination of extensive experience, verified documentation, quality-assured production, and a clear focus on long-term fire safety performance.
How does Woodsafe ensure long-term fire performance?
Long-term fire performance is a key aspect of the development and verification of Woodsafe’s fire protection solutions. Therefore, we continuously conduct research, testing, product development, and quality assurance to document how the performance of the fire protection system is affected over time.
Woodsafe’s products are tested and classified in accordance with relevant European standards. For products intended for exterior use, durability is verified, among other things, through testing in accordance with EN 16755, where fire performance is evaluated before and after standardized accelerated aging. For facade solutions, there are also documented system tests and full-scale fire tests that verify the fire performance of the entire structure.
At the same time, Woodsafe conducts extensive research and development on the natural aging of wood, exterior exposure, and long-term fire performance through ASSURED™, a research program that combines natural exposure and artificial aging with accredited fire testing in accordance with ISO/IEC 17025.
For the building owner, this provides a basis for decision-making grounded in documented verification, continuous research, and technical development—with a focus on how fire-retardant wood products perform, not only at the time of delivery but also throughout their intended service life.
Woodsafe’s ambition is not only to verify fire performance at the time of delivery—but also to build knowledge about how fire-retardant wood products perform throughout their entire intended service life.
What certifications and documentation does Woodsafe offer?
Woodsafe’s operations are based on verified quality, third-party-monitored production, and traceable documentation throughout the entire manufacturing process.
Depending on the project’s requirements, the documentation may include, among other things, CE marking, declarations of performance (DoP), classification reports, type approvals, Field of Application (FoA), documented service class according to EN 16755, full-scale facade tests according to SP FIRE 105, and other technical documentation relevant to the specific product and application.
The comprehensive documentation provides designers, contractors, inspection supervisors, and building owners with a clear basis for design, verification, and inspection. It contributes to a more efficient construction process and provides assurance that the selected solution is documented for its intended use.
Documentation is not just a requirement—it is the foundation for traceability, verification, and long-term fire safety and security.

How do I monitor fire safety throughout the construction process?
Fire safety measures should be monitored throughout the entire construction process—from design and procurement to delivery, installation, self-inspections, and final approval.
This means ensuring that design requirements, technical documentation, and the materials delivered and installed are consistent with the selected solution. Any deviations should be identified and addressed before installation or continued production.
A traceable and well-documented process facilitates self-inspections, verification, and the final handover of the building. At the same time, it reduces the risk of deviations, additional work, and unnecessary delays during the course of the project.
Continuous monitoring throughout the entire construction process is essential to ensure that the finished building meets the project’s requirements and documented fire performance.
