Lithuanian Fire Safety Regulations (STR 2.01:2004) and Kaunas Municipal Building Code Compliance
Compliance with STR 2.01:2004 in Kaunas requires that all glazed fire barriers meet specific fire resistance ratings based on building height, occupancy type, and escape route designation. For example, stairwell enclosures in residential towers exceeding five stories typically demand EI 60 performance, while corridor partitions in public buildings may require EI 30 or EI 120 depending on fire load and compartment size. The Lithuanian Fire and Rescue Department’s guidelines further stipulate that fire-rated glass must prevent flame penetration (integrity) and limit heat transfer (insulation) for the rated duration.
| Rating | Integrity (E) | Insulation (I) | Typical Application (Kaunas) |
| EI 30 | 30 min | 30 min | Corridor partitions in low-rise offices |
| EI 60 | 60 min | 60 min | Stairwells in residential high-rises |
| EI 120 | 120 min | 120 min | Compartment walls in warehouses |
Antifires’ 60-minute fire-rated glass systems are specifically engineered to meet these municipal requirements, using multi-layer intumescent gel technology that activates under heat to form a rigid insulating barrier. This ensures that even in historic Kaunas buildings with non-standard opening sizes, certified fire protection can be achieved without structural overhauls.
Fire Rated Glass Grade Selection: EI 30 to EI 120 Performance Parameters for Kaunas Projects
Selecting the appropriate fire resistance grade for Kaunas projects depends on the building’s fire safety strategy and the specific compartmentation requirements outlined in STR 2.01:2004. For stairwells and escape routes in residential towers, EI 60 is the most common specification, as it provides 60 minutes of both integrity and insulation—sufficient time for occupant evacuation and fire service intervention. In contrast, office lobbies and atrium enclosures may only require EI 30 when separated from main escape routes by other fire-resistant elements.
- EI 30 (30 min): Suitable for internal corridor partitions in low-to-mid-rise commercial buildings where fire load is limited and sprinkler systems are present.
- EI 60 (60 min): Mandatory for stairwell enclosures in buildings over 12 meters in height, as per Kaunas municipal amendments to STR 2.01:2004.
- EI 120 (120 min): Required for high-risk areas such as industrial warehouses, mezzanine floors, and storage compartments with combustible materials.
Antifires’ 120-minute fire-rated glass solutions utilize a 50mm multi-layer insulated structure that achieves both integrity and insulation for the full duration, making them ideal for Kaunas’s growing logistics and industrial sectors. All products are tested under BS EN 1634-1 and BS 476 Part 22, ensuring that the certified performance is traceable and verifiable for local fire inspections.
Kaunas Building Application Scenarios: Residential High-Rises, Office Complexes and Industrial Warehouses
Kaunas presents diverse application scenarios for fire-rated glass, ranging from the renovation of Soviet-era residential blocks to the construction of modern office complexes near Laisvės Alėja. In the city’s historic district, where building layouts often feature narrow corridors and shared stairwells, fire-rated glass partitions provide a transparent yet compliant solution for compartmentation without altering the original architecture. For example, in a typical five-story panel building, installing EI 60 glazed doors at stairwell entrances ensures that smoke and flames cannot spread between floors, meeting the requirements of STR 2.01:2004 for escape route protection.
- Residential High-Rises: Fire-rated glass in stairwells and corridor enclosures to maintain compartmentation and protect evacuation paths.
- Office Complexes: Glazed partitions in lobbies and meeting rooms that provide natural light while achieving EI 30 or EI 60 ratings.
- Industrial Warehouses: Fire-rated windows and doors in mezzanine areas and storage zones to contain fire spread and limit heat radiation.
Antifires’ fire-rated glass partition systems are designed for these varied environments, offering flexibility in frame materials (G.M.S. hollow steel sections) and glass thicknesses (10mm to 54mm) to match specific project requirements. In Kaunas’s new mixed-use developments near the Nemunas River, these systems enable architects to create open, light-filled spaces without compromising fire safety compliance.
Antifires Brand Advantage: Localized Compliance Support and Certified Product Traceability for Kaunas Clients
Antifires distinguishes itself in the Kaunas market through comprehensive localized support that streamlines the approval process for fire-rated glass installations. All products are accompanied by fire test certificates issued under BS EN 1634-1 and BS 476 Part 22, which are recognized by the State Fire Prevention and Rescue Department in Lithuania. For Kaunas clients, this means that documentation can be provided in both Lithuanian and English, facilitating direct submission to municipal building inspectors without the need for third-party translation or verification.
- Certified Traceability: Each glass unit is marked with a unique batch number linked to its test report, ensuring full transparency for audits.
- Expedited Logistics: Products are shipped via Klaipėda port, reducing lead times for Kaunas projects compared to suppliers based in Central Europe.
- On-Site Guidance: Technical support includes installation supervision for frame sealing, expansion gap management (3mm–5mm), and intumescent seal placement, all critical for maintaining the certified fire resistance.
By offering direct access to test data, localized documentation, and installation expertise, Antifires reduces the risk of project delays caused by non-compliance or documentation gaps. This end-to-end service model is particularly valuable for Kaunas developers navigating the intersection of national regulations and municipal building codes.
