Antifires ensures compliance with Bielefeld’s BauO NRW and DIN 4102 requirements by manufacturing all fire-rated glass assemblies to the EN 1634-1 test standard. Each product undergoes rigorous testing in accredited furnaces, where parameters such as furnace pressure (0 ±2Pa) and temperature rise on the unexposed side (average ≤ 140°C) are monitored. The resulting test reports provide clear evidence of performance classifications, such as EI 60 or EI 90, which directly satisfy the requirements of the BauO NRW. Additionally, the company provides a German technical documentation package that includes installation guidelines for ceramic wool seals and intumescent fire seals, ensuring that the system is installed in a manner consistent with the tested configuration. This full-chain traceability, from factory production to on-site installation, guarantees that the final assembly meets the strict legal standards required for building permits in North Rhine-Westphalia.
For Bielefeld office building partitions, the most common fire resistance ratings are EI 30 and EI 60, depending on the building’s height and occupancy classification. EI 30 is typically sufficient for corridor partitions and small office sub-divisions, where the primary goal is to contain a fire for a short duration to allow evacuation. EI 60 is more frequently specified for compartment walls that separate different tenant spaces or fire zones, as it provides a full hour of both integrity and insulation. For high-rise structures or buildings with specific fire safety strategies, EI 90 may be required for stairwell enclosures and lift lobbies. These ratings are validated under EN 1634-1 and align with the fire resistance durations defined in DIN 4102, ensuring that the glazing performs as a reliable barrier. For projects requiring specific performance, such as the 26mm door glass with 89 minutes of integrity, Antifires can supply certified solutions tailored to the design brief.
Yes, Antifires provides localized installation support for projects in the Ostwestfalen-Lippe (OWL) region, including Bielefeld. This support includes pre-installation technical consultations, where engineers review the project’s framing specifications and fire resistance requirements. The company also supplies detailed installation manuals that specify the correct use of M6/M8 anchor bolts at 300-600mm spacing and the proper application of ceramic fiber expansion gaps (3-5mm). For complex retrofits, such as those in the Sparrenburg district, Antifires can coordinate with local contractors to ensure that the installation methods align with the tested assembly configuration. This localized approach minimizes the risk of installation errors that could compromise the fire rating, providing Bielefeld project teams with the confidence that their fire-rated glazing will perform as certified.
