To achieve the fire protection requirements, different types of wood have different requirements
Fire tests are performed by third-party institutes to ensure that NTLs fire impregnation meets the requirements. However, it places certain demands on the construction, which is built with impregnated wood.
We help eachother with the sales process of fire retardant wood
For our customers, it should be easy to work with fire-impregnated wood. We have gathered some essential information below based on the most common questions we receive.
What is important to keep in mind when buying or selling fire retardant wood?
It can be confusing to navigate among the requirements for fire protection. Here we have put together a three-step process to get you started on ensuring you have found the right solution.
Does the fire protection achieve B-s1, d0 within the EU requirement EN 13501 - Reaction to Fire?
The fire classes that apply to surface layers on walls and ceilings consist of a main class for fire spread (A1-F) and additional classes for the amount of smoke and if there are burning drops.
The requirement for outer and inner panel is "B-s1, d0", which means main class B as well as minimal smoke development and no burning drops from the material.
Make sure your supplier has documentation that proves this fire class.
Is the fire protection durable over time?
Fire-protected wood, such as outer panels, is forced to endure many stresses from UV light, water and wind. To ensure fire class over time, our fire protection is coated with paint tested according to EN 927-6.
Are there any other requirements in the specification from the fire consultant?
Sometimes additional documentation is requested in connection with fire safety. These can be, for example, the fire test SP Fire 105 for facade constructions or emission tests for interior environments.
Talk to your supplier of materials or fire protection solution to see if they meet the required requirements.
Painting of fire-impregnated wood should always be certified
It is important to be aware that painting of fire-impregnated wood can affect the fire class. The end product should therefore be tested and approved with accompanying documentation for everyone's safety.
