NFRC Certificate for DAKO!

News New products


This time, we had our product’s level of energy-saving checked, which in recent years has become one of the key issues when choosing joinery. The result of the tests carried out is the award of the NFRC certificate for two  series of windows, which guarantees thermal insulation parameters at a sufficiently high level:

The procedure of examinations and analysis preceding obtaining these documents and certification is complicated and long-lasting, and the products are subjected to rigorous tests. Only the best products receive a certificate, the results of which are presented in the form of an energy label illustrating the values of their most important parameters such as Uw, Vt, Shgc . This allows us to easily compare products with each other, which significantly facilitates an informed choice for customers.



  • This certificate is issued by Keystone Certifications, Inc., which is a recognized research entity in the American market, bringing together all the major manufacturers of joinery.
  • The certification applies to DAKO’s own products, not the individual components.
  • The award of this certificate confirms the high quality and high thermal insulation parameters of the DPP-70 series.
