Fire safety for Basic, Medio+ and Pro+ I-Lock®

We have taken a stand – and that is why you can safely invite nature inside with I-Wood Denmark®. Fire performance is a crucial area, and therefore it is important for us to be able to document approved use of our panels.


Fire classification

I-Wood Denmark® has been subjected to a number of tests on our standard panels. I-Wood Denmark® Basic, Medio+ and Pro+ I-Lock® (ordinary MDF) have been tested in accordance with EN 13823 to prove that they fulfil a minimum of D-s2, d2, which is the requirement for domestic ceiling and wall panels.

For large-scale projects and buildings, we can also use B-s1,d0 raw materials/sub-components and various finishes. To discuss this further, contact I-Wood Denmark® and speak to our fire safety advisor.

Tested structures:

Increased fire classification requirements

If your project includes increased fire classification requirements, I-Wood Denmark can components including the following:

  • MDF, B-s1,d0-approved raw board
  • Felt, B-s1,d0-approved
  • Polyurethane varnish, flame-retardant

If you would like a specific surface treatment, or if your project requires a certain fire classification, then please contact us to discuss your needs and for advice concerning this. You might also require other types of materials, raw boards or veneers.
