Alu System Plus manufactures aluminium profile systems at Chrzanów, including the ASP80 FIRE+ fire-separation system, which the company describes as a system for fire partitions at EI 30 and EI 60. The system holds Krajowa Ocena Techniczna ITB-KOT-2017/0272 — its first edition covering internal fire and smoke-tight doorsets together with the wall kit — and a current ITB-KOT-2025/2746 for internal walls of the ASP80 system, both registered to the company at its Chrzanów address. It states that it tests and certifies with ITB and ift Rosenheim among others. The address here is taken from ITB’s register, because the company website renders its contact details in script.
