Every document below is the original issued by the testing or certification body. Where the original is in Polish, German or Italian, we have written the English summary ourselves — the summary is ours, the certificate is theirs. If you need an official English version for a permit or a tender, ask us and we will request it from Drutex.
All Drutex window lines are listed in the NFRC Certified Products Directory under manufacturer code DRU, and we quote those values without reservation. The IGLO PVC lines were removed from the NRCan ENERGY STAR Canada list in August 2026; Drutex has confirmed that re-applications are filed. We make no ENERGY STAR claim for those lines until they are listed again.
