Woodsafe® PRO™
Documented fire performance – verified for long-term durability
Woodsafe® PRO™ is an industrially fire-retardant treated wood with documented fire performance, a verified use class, and a Swedish Type Approval. Manufactured under continuous third-party supervision in a CO₂-neutral production process, it provides a reliable basis for decision-making in projects with demanding requirements for quality, safety, and long-term durability.
Woodsafe® PRO™ - Documented fire protection for interior and exterior wood applications
Woodsafe® PRO™ is a well-established solution for the industrial fire-retardant treatment of solid wood and plywood. The product combines documented fire performance with the natural beauty of wood and can be applied to a wide range of timber species, including Scots pine, spruce, birch, larch, ash, cedar, maple, and oak.
This provides architects, contractors, and specifiers with extensive opportunities to use wood in environments with demanding fire safety requirements—from schools, sports arenas, and concert halls to hotels, public buildings, and painted timber façades, provided that the applicable coating specifications and installation guidelines are followed.
Woodsafe® PRO™ was the first fire-retardant treated wood (FRTW) to be CE certified under the European Construction Products Directive (CPD 89/106/EEC). Since 2013, the product has been covered by the EU Construction Products Regulation (CPR 305/2011), meaning that its performance is declared and continuously assessed in accordance with applicable European legislation.
Since 2008, Woodsafe® PRO™ has also been covered by a Swedish Type Approval issued by a notified body. The Type Approval verifies that the product complies with the requirements applicable within its intended scope of use under Swedish building legislation and provides additional documentation to support specification, building control, and regulatory approval.
Although Swedish Type Approval is no longer mandatory, Woodsafe has chosen to maintain this independent verification. It reflects our commitment to providing documented solutions with a high level of traceability, quality, and long-term reliability. For us, it is a natural part of our ongoing commitment to quality assurance, technical documentation, and dependable long-term performance.
In addition, Woodsafe® PRO™ is approved according to EN 16755 for use classes INT1, INT2, and EXT. This means that the durability of its fire performance has been verified in accordance with the standard's test methods for the respective service environments. For exterior applications, the classification applies in combination with the specified surface coating system and the associated application guidelines.

General information
General information
In our impregnation process, the wood and the wood product are wetted in their entirety and, depending on the product, 2-15% by weight of fire retardant is pushed deep into the cell structure of the wood, where it is fixed.
The combination of moisture and drying means that an initially finished planed, sawn or processed wood product can become slightly crooked and warped compared to untreated wood. The better the quality of the wood product, the better the final product.
In the fire impregnation process, the wood is soaked with water mixed with fire impregnation agent and then dried. The impregnation process also means that dimensional changes depending on the type of wood and plywood can occur, even within the framework of the same quality grading, which can result in the dimensions of the wood materials changing differently.
Dimensional change may deviate from planing tolerance and plywood tolerance, which is considered ok because the impregnation process takes place after planing and the production of plywood. It is the responsibility of the client/customer to take these conditions into account when ordering Woodsafe's contractor impregnation services through partners.
