The requirements of the AgBB scheme are not fulfilled in this measurement with the STEICOflex
036. But taking into account that the main emitter of the wood fibre insulation board is acetic
acid, and this is a wood's own ingredient, which is generated during the manufacturing process
and is therefore also subject to significant fluctuations from batch to batch, the wood fibre insu-
lation board is a high-quality product made from renewable raw materials from the point of
view of the Institute for Building Biology Rosenheim and will continue to be awarded the test seal
by us. It should also be noted that wood fibre insulation boards are not in direct contact with the
interior climate but are somewhat shielded by foils or other building boards, which normally
leads to significantly lower emissions of acetic acid into the living area.
After 28 days the R-value without acetic acid is only 0.4, the TVOC-value is only 43 μg/m³.
Evaluation:
Based on the measurement results and the comparison of measures according to the AgBB
schema as well as the approval principles of the DIBt, exposure to emissions of volatile organic
compounds due to the tested wooden fibre boards is not expected. Using the boards in the in-
terior rooms of buildings is therefore harmless to health in regards to VOC emissions (remarks on
STEICOflex036 are above).
