Our quality certificates

In Diksmuide, we operate the biggest PVC recycling plant in the Benelux. To make sure we deliver the best quality window profiles, our recycling activities are independently audited by EuCertPlast, the European Certification of Plastics Recycling. This certification aims at environmentally optimal plastics recycling processes. As such, we contribute to the Recovinyl and Vinyl Plus 2030 European recycling objectives.

VinylPlus Product Labels

Our European product ranges Elegant, Elegant Thermofibra, Zendow, Zendow#neo, and Twinson have received a VinylPlus® Product Label. This label confirms that our products and processes apply to the highest quality, performance, and sustainability standards.

To attain this prestigious label, our products had to meet the following requirements:

  • Sourcing of traceable raw materials
  • Reduced waste policy and use of recycled material
  • Sourcing of PVC sourced from ECVM chartered suppliers, which conform to high standards of control over processes, operations and any emissions to the natural environmentµ
  • Sustainable use of additives
  • Energy efficiency and use of renewable energies

Recovinyl: recycling monitor

Recycling old PVC windows is an important part of our sustainability policy. With a capacity of 40,000 tonnes per year, our recycling plant in Belgium is the biggest in the Benelux. Our recycling activities are monitored by Recovinyl, the PVC industry’s recycling scheme. This means certified auditors check and verify the tonnages of recycled PVC we report every year.

ISO 14001 & ISO 9001 quality certificates

Just like you, we expect our PVC windows to have top-notch quality. That’s why our integrated quality management system has top priority. Obtaining the ISO14001 and ISO9001 certificates is a natural result of our yearlong efforts in sustainability and quality management. It helps us to continuously improve and make sure we maintain the highest standards in the industry.

The ISO 14001 certificate is internationally recognised as the leading environmental management system standard, focusing on environmental protection, pollution prevention, waste minimisation, and energy and materials consumption reduction. These are topics we feel very strongly about, so we’re proud to be able to offer you our environmental management guarantee.

Our ISO 9001 certificate proves we have a solid quality management system, focusing on recycling, compounding, tooling, extrusion, and finishing of high-quality plastic profiles for the construction industry, including the logistics that comprise the entire life cycle, from the acquisition to the loading of goods on trucks.

These certificates give you peace of mind, ensuring you that at Deceuninck, we are committed to the quality and sustainability of our products.
