Our qualifications


All PEG insulators are tested in our labs and undergo orientation tests, after checking their thermal conductivity on a lambdameter internally. They are then certified by competent laboratories (CSTB, LNE...).

Certification ATE n° 11/0421 :

  • OEKO-TEX: Certificat OEKO-TEX n° CQ 886/1
  • CERTIFICAT WESSLING: Results A+ (emissions in indoor air)

Wessling quality label guarantees the quality and safety of products. Products are free from harmful substances, and the consumer can trust the manufacturer's declarations. It helps consumers in their decision for a product.


Our isolators suffered fire orientation tests at CSTB. The results of fire behavior are very positive.
