5. 1. 7. Limits for VOC and SVOC emissions from wood fibre insulation materials


description relevant product categories 

explanation

Wood fibre insulating materials can emit various substances. In addition to formaldehyde (if binders containing formaldehyde are used), these substances may include volatile and semi-volatile organic compounds (VOCs and SVOCs) such as aldehydes, terpenes from wood components, as well as short-chain carboxylic acids, particularly acetic acid and formic acid.

 
minimum requirement

If insulation materials are installed facing the interior, without a wind-tight layer separating them from the indoor air, the following criteria for emission behaviour must be met:

 

Parameter

Max. test chamber concentration after 28 days

Carcinogenic substances classified as Categories 1A and 1B under CLP Regulation 1272/2008 (C-substances) 1 µg/m³ (not quantifiable)

Total of volatile organic compounds C6–C16 (TVOCs without acidic acid)

300 µg/m³

Acidic acid

600 µg/m³

Total of semi-volatile organic compounds C16–C22 (TSVOCs)

100 µg/m³
Formaldehyde*) 0,05 ppm*)

 

*) Proof required only for insulation materials with binders containing formaldehyde.

Proof:

Test report of an accredited testing laboratory, with test chamber procedure in accordance with ÖN EN ISO 16000 (-3),-6,-9,-11 and ÖNORM EN 16516. Test specifications according to AgBB-Scheme 2018, with a space loading of ≥ 0.5 m²/m³ for wood and wood-based panels. For older measurements, tests according to AgBB-Scheme 2015 are also accepted. The test certificate must not be more than 5 years old.

 
All products awarded one of the following eco labels meet these criteria:

  • natureplus quality label (Award Guidelines RL0104, RL0201)
  • Blauer Engel/Blue Angel (Guideline DE-UZ 132)
