1. Product description
For the purpose of awarding the seal of approval, the company has instructed us to subject its
products to building biology follow-up testing based on follow-up testing conducted in 2017
(expert report no. 3018 - 991). The products were collected from the customer on 07 October
2019 by official supervision of Instytut Technologii Drewna, Poznan. IBR received the original
sampling protocols for review.
In terms of materials technology, the products submitted for testing are upgraded wood fibre-
board according to EN 622-1 and EN 622-4 and/or EN 13171 as well as other wood fibre materi-
als for construction applications.
All test results are summarised for the products below:

Typical areas of application are thermal and acoustic insulation in the building trade. Lignin
found naturally in wood is released in the production process. This is adequate as a binding
agent in order to bind the panel materials produced under pressure and heat and to achieve
adequate strength and stiffness. The soft wood fibreboard is also produced in a bituminised ver-
sion. This makes the panel materials permanently resistant against moisture penetration. Only
small-diameter timber and untreated residual coniferous wood from the sawing industry is used
in production, relieving the forest industry and taken from sustainable forestry operations. Forest
thinnings are used among others. Used wood which may be contaminated is excluded. PU resins
and paraffins are also used as binding agents and for hydrophobising.
Similar to panel-shaped wood-based materials and/or thermal insulation felt materials, all com-
mon wood processing tools can be used. While dust generated during processing is not hazard-
ous to health, it should largely be avoided.
The need to use personal protective equipment when processing the material within the scope
of the standards stipulated by the employer’s liability insurance associations is pointed out ex-
plicitly. Persons charged with processing these materials can make use of readily available assis-
tance. Comprehensive product information and processing regulations can be viewed on the
manufacturer’s Internet site or can be found in the product-specific printed documentation.
It is subject to constant third party monitoring and controls by the manufacturer. The local appli-
cation of additives or coating which might be necessary is not part of the examination. For more
