Aligning with Portuguese Decree-Law 220/2008 and EN 13501-2 Fire Resistance Classifications
Compliance with Decree-Law 220/2008 in Aves requires a precise understanding of how fire resistance ratings translate to building elements. This regulation, which transposes European directives into Portuguese law, demands that glazed assemblies in escape routes, fire compartments, and facades meet specific performance levels. Antifires directly addresses this by offering products classified under EN 13501-2, the European standard for fire classification of construction products. This classification system uses a unified nomenclature—E for Integrity, I for Insulation, and W for Radiation—to define the capability of a product to contain fire.
For commercial projects in Aves, such as office buildings and retail spaces, the required rating often falls within the EI 30 to EI 60 range for internal partitions and doors. In contrast, high-risk industrial facilities or storage buildings may necessitate EI 90 to EI 120 performance. Antifires’ product line includes certified assemblies that have been tested to these exact thresholds. For example, our 28mm EI60 panel construction (6mm + 5.5mm gel + 5mm + 5.5mm gel + 6mm) provides verified integrity and insulation performance, while our 50mm and 54mm EI120 systems offer the highest level of protection for critical compartment lines.
To simplify specification, Antifires provides detailed technical datasheets that cross-reference our product codes with the relevant EN 13501-2 classes. This ensures that every fire partition solution installed in Aves is fully traceable to its test evidence, providing clear audit trails for local fire safety engineers and regulatory authorities.
Selecting Fire Rated Glass Grades for Aves: EI and EW Performance with Insulating Glass Units
Selecting the appropriate fire rated glass grade for a project in Aves involves analyzing the specific performance requirements for integrity, insulation, and radiant heat transfer. Antifires offers two primary performance categories: EI-class (Integrity and Insulation) and EW-class (Integrity and Radiation control). The choice between these categories depends on the building’s fire strategy and the location of the glazed element.
For internal partitions and doors that must limit temperature rise on the unexposed side to protect occupants and adjacent materials, EI-class glass is essential. Our 26mm door glass (5mm + 5.5mm gel + 5mm + 5.5mm gel + 5mm) achieves an integrity rating of 89–90 minutes and an insulation rating of 68 minutes, making it suitable for escape route enclosures. For applications where radiant heat control is the primary concern—such as in corridors where direct exposure to flames is unlikely but heat transfer must be minimized—EW-class glass provides a cost-effective solution.
The structural composition of these glasses involves multiple layers of tempered glass and intumescent interlayers. For instance, the 10mm FPOS (3mm float + 4mm gel + 3mm float) offers 135 minutes of integrity, while the 15mm FPOS multi-layer structure provides up to 132 minutes of integrity with 33–34 minutes of insulation. These configurations are available as insulating glass units that also meet thermal efficiency standards, a common requirement in Aves’s mixed-use developments where energy performance and fire safety must coexist.

Integrating Fire Rated Glass in Aves’s Historic Renovations and New Industrial Facilities
Aves presents a unique architectural challenge, combining historic stone and timber buildings in the city center with modern industrial parks on the outskirts. Antifires’ fire rated glass systems are engineered to integrate seamlessly into both contexts, providing certified fire safety without compromising the aesthetic or structural integrity of the original design. In historic renovations, the focus is on preserving sightlines and material authenticity while upgrading passive fire protection to current standards.
For heritage buildings, our slim-profile 10mm FPOS and 15mm FPOS systems can be installed within existing timber or steel frames, using 3mm to 6mm ceramic wool and intumescent fire seals (20mm x 4mm) to maintain the fire barrier. The glass is fixed with M6 or M8 anchor bolts at 300–600mm spacing, respecting the original masonry without excessive alteration. In these scenarios, EI 30 to EI 60 ratings are typically sufficient to meet the requirements of Decree-Law 220/2008 for limited occupancy heritage structures.
In contrast, new industrial facilities in Aves—such as factories and logistics centers—require robust fire compartmentation to protect large open spaces and high-value equipment. Here, Antifires specifies 50mm and 54mm EI120 multi-layer insulated glass systems, which provide up to 120 minutes of both integrity and insulation. These systems are installed in G.M.S. hollow steel frames with 12mm to 15mm fire-rated insulation boards, capable of withstanding the thermal and mechanical stresses of a fully developed fire. The same fire rated glass can be used as vision panels in factory fire doors, allowing for natural light and visual monitoring without compromising the compartment’s fire resistance.
Why Aves Builders Trust Antifires: EN-Certified Products and Localized Technical Support
Builders and specifiers in Aves choose Antifires for a combination of certified product performance and localized technical support that simplifies compliance. All our fire rated glass and door assemblies carry EN 16034 and CE marking, providing a clear declaration of performance that is recognized across the European Union, including Portugal. This certification directly supports compliance with Decree-Law 220/2008, as it provides the necessary test evidence for building control authorities in Aves.
Our localized support includes the provision of Portuguese-language technical documentation, including installation manuals, maintenance schedules, and fire safety declarations. This documentation is critical for contractors and architects who must submit compliance reports as part of the building approval process. Additionally, Antifires offers on-site compliance guidance, where our technical team can review installation details and ensure that framing, sealants, and fixings meet the tested configuration. For example, we specify the correct use of ceramic tape (density 210 kg/m³) and expansion gaps of 3mm to 5mm filled with ceramic fiber to maintain the integrity of the fire seal.
Logistically, Antifires leverages European distribution hubs to ensure rapid delivery to Aves and the surrounding Porto district. This minimizes project delays and allows for just-in-time delivery schedules. By combining certified products with localized expertise, Antifires reduces the risk of non-compliance and ensures that every installation meets the rigorous standards demanded by Portuguese fire safety regulations.
