Bremen’s Fire Protection Compliance: Adapting to the Landesbauordnung and EN 1363 Standards
Bremen's building projects must navigate the specific requirements of the Landesbauordnung Niedersachsen/Bremen, which aligns with the national Musterbauordnung (MBO) to enforce fire resistance ratings (F30 to F90) for glazed assemblies. These regulations are directly tied to the European fire testing framework, primarily EN 1363-1 for general fire resistance and EN 1634-1 for door and window assemblies. Antifires ensures that its fire rated glass systems are tested and classified under these standards, providing documented proof of performance for local authority approval. The classification system, defined by EN 13501-2, categorizes products into integrity-only (E), insulation (EI), and radiation control (EW) classes, which are directly referenced in Bremen’s building codes. For example, a typical requirement for escape route windows in commercial buildings is EW60, limiting radiant heat transfer to protect occupants. By integrating these standards, our solutions offer a clear compliance pathway, supported by test reports from accredited laboratories such as MPA NRW, ensuring that every installation meets the stringent safety benchmarks set by Bremen’s Bauaufsicht.
Technical Specifications for Bremen: Selecting EI and EW Fire Rated Glass Grades for Industrial Use
For Bremen’s diverse industrial landscape, including logistics hubs in Überseehafen and manufacturing facilities, selecting the correct fire resistance class is critical. Antifires provides EI-classified fire rated glass (integrity and insulation) for compartment walls, which must limit temperature rise on the unexposed side to an average of ≤140°C and a maximum of ≤180°C over the test duration. This is essential for maintaining structural stability and preventing fire spread in high-risk zones. For escape route windows and vision panels in stairwells, EW-classified glass (integrity and radiation control) is specified, ensuring that radiant heat does not exceed 15 kW/m² at a distance of 500mm from the unexposed surface. Our product range includes certified thicknesses from 12mm to 30mm, achieving up to 120 minutes of fire resistance (EI120) under EN 13501-2 classification. The following table summarizes typical grades for Bremen’s industrial applications:
| Application | Class | Typical Rating | Glass Thickness |
| Compartment Walls | EI | EI60–EI120 | 21mm–54mm |
| Escape Route Windows | EW | EW60–EW120 | 10mm–15mm |
| Fire Doors | EI | EI30–EI60 | 26mm–28mm |
Bremen Building Applications: Fire Rated Glass for Logistics Centers and Historic Renovations
Bremen’s urban development presents unique challenges, particularly in logistics centers within the Überseehafen district and historic renovations in the Schnoor quarter. For logistics hubs, Antifires supplies fire rated glass systems that achieve F90-rated fire separation, utilizing multi-layer composite structures with intumescent gels that expand under heat to maintain integrity. These systems are designed for large-span glazing in loading bays and warehouse partitions, where structural deflection (up to 152mm toward the furnace) must be accommodated without compromising the fire barrier. In historic buildings, such as those in the Schnoor quarter, preserving the original facade appearance is paramount. Antifires offers narrow-profile fire doors and windows that integrate seamlessly with heritage aesthetics, using steel frames with ceramic wool and intumescent seals (20mm × 4mm) to meet F90 ratings without altering external sightlines. These solutions are tested to EN 1634-1 for doors and EN 1364-1 for partitions, ensuring that both modern industrial and sensitive retrofit projects achieve certified fire protection while respecting architectural integrity.
Why Bremen Clients Trust Antifires: Localized Support and EN-Certified Product Traceability
Bremen clients choose Antifires for our localized technical support and full traceability of CE-marked products under the Construction Products Regulation (EU) 305/2011. Each fire rated glass unit is documented with test reports from accredited German laboratories, such as MPA NRW, ensuring compliance with EN 12150-1 (thermally toughened glass) and EN 14179-1 (heat-soaked glass). This traceability streamlines approval processes with Bremen’s Bauaufsicht, reducing project delays. Our team provides on-site consultation for system selection, including frame specifications (G.M.S. hollow steel sections) and installation parameters (expansion gaps of 3mm–5mm filled with ceramic fiber). For detailed product specifications, explore our 120-minute fire rated glass solutions for high-demand applications. Additionally, our fire door systems are tailored for Bremen’s commercial and industrial projects, ensuring full liability coverage and expedited local approvals.
