DRE Nefryt RC3 EI30 is the EI30 version of an interior entrance door that combines the manufacturer’s specified security, fire, and smoke classifications. Its leaf uses a glued softwood frame with a special multilayer filling, a three-point hook strip lock, three three-part hinges, anti-pry pins, and intumescent seals for the EI30 version. DRE lists use in residential, public, shared residential, utility, and technical interior locations. The door is selected as a complete entrance assembly, with its frame, threshold, fittings, and closing components matched to the specified configuration. The EI30 version must remain distinct from the separate Nefryt RC3 version in the catalogue, since the fire-related components and quoted configuration are different.
For Nefryt RC3 in the EI30 version, DRE publishes RC3 under PN-EN 1627:2021, EI2 30 fire resistance, and Sa4/S200 smoke classifications. The acoustic result also depends on the frame and threshold. The catalogue lists Rw 42 dB with the OSH2 or OSH LUX hybrid steel frame and a metal threshold, and Rw 41 dB with the OSS2 fixed steel frame and metal threshold. Those results should stay attached to their named configurations when comparing proposals. A frame choice therefore changes more than the appearance of the opening. Record the selected frame and threshold beside the leaf, and retain the EI30 version in the order rather than relying on the broader collection name alone.
The catalogue lists nominal width codes from 80E through 100E and CPL laminate finish groups for the surface selection. The EI30 door should be equipped with a closer as specified by the manufacturer. Listed additions include the appropriate handle, escutcheon, cylinder, viewers, additional lock options, and closing devices. Fire-related viewer or hardware selections need to follow the intended assembly. Review the entrance’s opening direction and finished-floor detail before finalizing the threshold and frame. The starting amount covers the EI30 leaf in the stated laminate group; it is different from a complete-set illustration for the separate RC3-only version. Frame, handle, threshold, and the required closing arrangement complete the ordered entrance.
