Kaunas Certified Fire Rated Glass and Fire Doors for Lithuanian Building Compliance

In the city of Kaunas, Lithuania, building safety compliance is governed by the national regulation STR 2.01:2004 “Fire Safety. Basic Requirements”, which establishes mandatory fire resistance ratings for glazed elements in residential, commercial, and public structures. This standard, enforced by the Lithuanian Fire and Rescue Department, requires that fire-rated glass and door assemblies used in escape routes, stairwells, and compartment walls achieve certified performance levels such as EI 30, EI 60, or EI 120. For a comprehensive overview of the national regulatory framework, refer to the official STR 2.01:2004 text on the Lithuanian e-Seimas portal.

Antifires supplies fully certified fire-rated glass and door systems that meet these localized requirements, ensuring that Kaunas architects, contractors, and building owners can achieve compliance without compromising design flexibility. Our products are tested under BS EN 1634-1 and BS EN 1364-1 standards, providing verified integrity (E) and insulation (I) performance. Whether for new mixed-use developments near the city center or renovations of Soviet-era panel buildings, Antifires delivers solutions that align with both municipal building codes and European fire safety directives. By integrating certified fire-rated glass into partitions, doors, and windows, projects in Kaunas benefit from enhanced compartmentation, smoke control, and evacuation path protection—critical factors in multi-story residential towers and office complexes.

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.

RatingIntegrity (E)Insulation (I)Typical Application (Kaunas)
EI 3030 min30 minCorridor partitions in low-rise offices
EI 6060 min60 minStairwells in residential high-rises
EI 120120 min120 minCompartment 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.
