CTE DB SI Compliance Requirements for Fire Protection in Zaragoza Buildings
Zaragoza's construction sector must rigorously follow the CTE DB SI regulations, which specify fire resistance ratings for glazed elements based on building height, occupancy type, and evacuation routes. For commercial high-rises and residential towers, particularly in mixed-use developments along the Ebro River, the standard demands minimum EI 60 for partition walls and EI 30 for doors in escape corridors. These requirements are derived from European test methods such as BS EN 1364-1: 1999, 2015 and BS EN 1634-1: 2008, 2014, which assess both integrity (E) and insulation (I) performance. The CTE DB SI also mandates that fire-rated glazing maintain structural stability under furnace pressures of 0 ±2 Pa after 5 minutes, with maximum deflection limits of 38 mm to 152 mm toward the furnace side. Antifires supplies systems that meet these criteria, using G.M.S. hollow steel frames with 3 mm to 6 mm ceramic wool (density 210 kg/m³) for expansion gaps, ensuring compliance with local building codes.
Fire Rated Glass Grade Selection Based on Zaragoza’s Climatic and Structural Demands
Selecting the appropriate fire-rated glass grade in Zaragoza requires balancing safety with architectural constraints, especially in historic districts like El Tubo. Here, retrofits must align with heritage preservation laws while achieving EN 13501-2 classifications for integrity and insulation. For example, the 10 mm FPOS structure (3 mm float glass + 4 mm fire gel + 3 mm float glass) offers 135 minutes of integrity and 16 minutes of insulation, making it suitable for internal partitions where space is limited. In contrast, the 21 mm FPOS multi-layer composite provides 120 minutes of integrity and 30 minutes of insulation, ideal for stairwell enclosures in older buildings. The table below summarizes key options:
| Glass Type |
Integrity (min) |
Insulation (min) |
Typical Application |
| 10 mm FPOS |
135 |
16 |
Internal partitions in historic retrofits |
| 21 mm FPOS |
120 |
30 |
Stairwell enclosures |
| 28 mm EI60 |
66 |
64 |
Fire-rated doors in common areas |
These solutions use intumescent gel layers that expand under heat, maintaining insulation performance even when surface glass cracks within 2–4 minutes of exposure.
Engineering Project Demands for Fire Doors and Windows in Zaragoza’s Urban Expansion
In Zaragoza's rapidly expanding logistics hubs, such as Plaza Logística, fire-rated windows and sliding doors are critical for warehouse separation zones. These facilities, often housing high-occupancy storage of flammable materials, require systems with EI 90 ratings to reduce fire spread risks. The 6 mm E90 glass (tested to BS 476 Part 22: 1987) provides 90 minutes of integrity and is installed using M6/M8 anchor bolts at 300–600 mm spacing within steel frames. For larger openings, the 50 mm ultra-high-performance glass achieves 120 minutes of integrity and insulation, meeting the demands of fire compartmentation in logistics centers. 120-minute fire rated glass with integrity and insulation is particularly suited for these environments, where thermal insulation prevents radiant heat transmission (W) to adjacent zones. Installation protocols require 12 mm to 15 mm fire-rated insulation boards and 20 mm × 4 mm intumescent fire seals to ensure gap integrity under furnace conditions.
Antifires Brand Advantages for Zaragoza Customers: Localized Certification and Just-in-Time Delivery
Antifires offers distinct advantages for Zaragoza customers, including EN 16034 and CE-marked fire-rated glass, doors, and windows with pre-verified documentation. This eliminates delays in municipal inspections for both new builds and retrofits. The company's just-in-time delivery model ensures that products arrive on-site with complete compliance paperwork, including test reports referencing BS EN 1364-1: 1999, 2015 and ASTM E119 standards. For projects requiring specific ratings, Antifires provides systems like the 26 mm door glass (5 mm + 5.5 mm gel + 5 mm + 5.5 mm gel + 5 mm), which achieves 89–90 minutes of integrity and 68 minutes of insulation. 90-minute fire rated glass for doors and windows is a popular choice for commercial applications. All products are backed by certified test data from accredited laboratories, ensuring that Zaragoza's architects and contractors can confidently meet CTE DB SI requirements without compromising design flexibility.
