Dayton Fire Safety Compliance Standards for Building Envelope Systems
Dayton’s building envelope systems must address multiple safety parameters, with fire resistance being a primary concern for life safety. The OBC requires that glazing in fire-resistance-rated walls maintain both integrity (E) and, in specific applications, insulation (I) to prevent radiant heat transfer that could ignite adjacent materials. Antifires validates all assemblies under the positive pressure protocol, which simulates real fire conditions more accurately than neutral pressure tests. This testing ensures that the glass and frame system can withstand the dynamic forces of a fire without failing prematurely. For example, an EI60 rated assembly, such as the 28mm multi-layer panel, provides 60 minutes of both flame containment and thermal insulation, limiting the average temperature rise on the unexposed side to ≤140°C. In contrast, an E90 integrity-only system, like the 6mm single-layer glass, is suitable for locations where insulation is not required by code, such as certain corridor glazing. The selection criteria also involve the framing system; Antifires uses G.M.S. hollow steel sections with ceramic wool and intumescent seals to accommodate thermal expansion and maintain the seal. For Dayton’s mixed-use developments, where warehouse-to-office conversions are common, these systems allow for large expanses of daylighting without sacrificing code compliance. The table below summarizes key performance distinctions for typical commercial applications:
| Rating Type | Standard | Typical Application | Glass Structure Example |
| E90 (Integrity Only) | UL 10C / NFPA 252 | Exit corridors (when sprinklered) | 6mm single-layer tempered |
| EI60 (Integrity + Insulation) | ASTM E119 / BS EN 1634-1 | Stairwell enclosures | 28mm multi-layer with gel |
| EI120 (Integrity + Insulation) | ASTM E119 / BS 476 Part 22 | Vertical shafts / fire barriers | 50mm insulated composite |
Fire Rated Glass Selection Criteria for Dayton’s Industrial and Institutional Settings
In Dayton’s industrial and institutional settings, the selection of fire-rated glazing must address specific project hazards and occupancy classifications. For exit corridors and stairwell enclosures, the OBC often mandates a 1-hour or 2-hour fire-resistance rating, depending on the building height and occupant load. Antifires offers a range of systems that meet these requirements without compromising natural light transmission, which is critical for wayfinding and occupant well-being. For instance, the 21mm FPOS composite glass provides 120 minutes of integrity and 30 minutes of insulation, making it suitable for vision panels in 2-hour rated walls. The glass structure incorporates multiple layers of tempered glass with intumescent interlayers that activate under heat, forming an opaque insulating shield. This characteristic is particularly valuable in light industrial facilities where visibility into production areas must be maintained under normal conditions but blocked during a fire event. For warehouse-to-office conversions—a common trend in Dayton’s redevelopment zones—the framing system must also accommodate existing structural deflections. Antifires uses M6/M8 anchor bolts at 300–600mm spacing and a 3–5mm expansion gap filled with ceramic fiber to allow for thermal movement without compromising the fire seal. The following list outlines key selection criteria for these environments:
- Rating Duration: Match the required hourly rating (e.g., 60, 90, 120 minutes) per OBC Table 716.
- Insulation Requirement: Determine if the code mandates EI rating for the specific location (e.g., stairwells vs. corridors).
- Frame Compatibility: Ensure the frame is tested with the glass as a complete assembly for positive pressure conditions.
- Daylighting Goals: Select multi-layer gel-filled glass for high light transmission (up to 85%) while achieving insulation.
Dayton Building Application Scenarios: Healthcare, Education and Light Industrial Projects
Dayton’s diverse building stock—ranging from historic school buildings to modern healthcare facilities and light industrial parks—requires tailored fire-rated glass solutions. In healthcare settings, such as hospitals and outpatient clinics, the OBC mandates smoke-resistant and fire-rated glazing in corridors and patient room doors to compartmentalize fire and facilitate safe egress. Antifires’ 26mm door glass, which achieves 90 minutes of integrity and 68 minutes of insulation, is ideal for these applications. Its multi-layer construction (5mm + 5.5mm gel + 5mm + 5.5mm gel + 5mm) provides robust thermal performance while allowing staff to visually monitor patients. For educational facilities, such as Dayton Public Schools, renovation projects often require 45-minute or 1-hour rated glazing in exit corridors and stairwells. The 10mm FPOS glass, with 135 minutes of integrity, offers a cost-effective solution for vision panels in fire doors, meeting the code while maintaining a transparent aesthetic. In light industrial projects, such as manufacturing plants or logistics centers, large glazed partitions are often used to separate office areas from production floors. Here, the 50mm EI120 system provides both integrity and insulation for 120 minutes, meeting the highest local requirements for fire barriers. The table below summarizes typical applications and recommended products for Dayton projects:
| Project Type | Typical Requirement | Recommended Product | Key Performance |
| Healthcare (Hospitals) | EI60 in corridors | 28mm EI60 panel | Integrity 66 min, Insulation 64 min |
| Education (Schools) | E90 in exit doors | 6mm E90 glass | Integrity 90 min |
| Light Industrial | EI120 in fire barriers | 50mm EI120 composite | Integrity & Insulation 120 min |
Why Dayton Contractors Trust Antifires for Fire Rated Glass and Door Systems
Dayton contractors and specifiers consistently choose Antifires for fire-rated glazing systems due to the company’s unwavering commitment to tested performance and code compliance. Every assembly—from the glass to the frame and seals—is validated under recognized standards such as UL 10C, NFPA 252, and ASTM E119. This comprehensive approach eliminates the risk of component mismatch, which is a common cause of failure during municipal inspections. For example, the use of intumescent fire seals (20mm × 4mm) and ceramic wool (3–6mm, density 210 kg/m³) in the framing system ensures that thermal expansion does not compromise the fire barrier. Furthermore, Antifires provides detailed installation manuals and technical data sheets that include specific anchoring patterns and gap tolerances, enabling contractors to achieve a reliable installation on the first attempt. The company’s product lines, such as 90-minute integrity-only glass for doors and partitions, offer a direct path to compliance for Dayton’s most common commercial applications. Additionally, the availability of 120-minute integrity and insulation glass systems addresses the highest local requirements for fire barriers and vertical shafts. By providing complete, certified assemblies rather than individual components, Antifires reduces liability for contractors and ensures that the final installation meets the rigorous standards of the Ohio Building Code.
