90-Minute Fire-Rated Door

What is a 90-minute fire-rated door?

A 90-minute fire-rated door, also known as an EI90 fire-rated door, is designed and manufactured in accordance with international Integrity and Insulation standards. This feature allows the door to maintain its Insulation (I) performance for up to 90 minutes. Accordingly, in the event of a fire, the door is capable of resisting flames, blocking heat transfer, preventing toxic gases, and inhibiting the spread of fire to adjacent spaces.

The 90-minute fire-rated doors manufactured by Adamco Construction and Investment Joint Stock Company maintain Integrity (E) throughout the full 90-minute duration and comply with ISO 9001:2015 quality management standards. This enables the door to retain its original shape and structural properties even when exposed to extreme temperatures, thereby protecting assets and minimizing risks to human life and property.

With a strong orientation toward FDI customers, Adamco designs and manufactures EI90 fire-rated doors that meet not only Vietnamese PCCC requirements but also the technical specifications, documentation standards, and quality expectations commonly required in foreign-invested factories, industrial parks, and international projects.

Evaluation of EI90 fire-rated steel door performance

EI90 fire-rated steel doors are increasingly becoming a preferred choice for a wide range of projects. The following functional advantages have contributed to the growing recognition of this product line.

Fire resistance

Effective fire resistance provides valuable time for emergency response. The door does not deform or melt under high temperatures for up to 90 minutes during a fire. This ensures enhanced protection of people and property while preventing the spread of fire. The extended fire-resistance duration of up to 1 hour and 30 minutes is a key advantage that makes this product highly favored.

Non-combustibility

The triple-layer door structure with a high-grade fire-resistant core does not ignite when exposed to fire. Acting like protective armor, it prevents fire propagation and safeguards surrounding areas.

Smoke resistance

The product is equipped with fire-resistant rubber seals made from permanently elastic rubber, capable of expanding in response to rising temperatures. This effectively seals door gaps, preventing smoke penetration. In addition to blocking smoke, it helps protect post-fire health by preventing the intrusion of toxic gases and substances harmful to the respiratory system, heart, and lungs.

Toxic gas resistance

The door effectively blocks toxic gases during a fire, providing superior fire-protection support compared to many alternative products. This helps users avoid symptoms such as headaches, dizziness, vertigo, and shortness of breath, enabling clearer awareness and easier evacuation.

Hot air insulation

The door prevents hot air from spreading to other rooms during a fire, while also helping retain warmth in winter and reducing cooling loads in summer. The clean and refined space created by this product contributes to improved working efficiency and enhanced rest quality.

Anti-theft capability

Its anti-theft performance is highly rated thanks to a standardized steel sheet frame with excellent load-bearing capacity. Strong impacts such as hammering or stone strikes do not cause the door to dislodge or suffer structural damage. With a triple-layer construction, stainless steel locks, and robust hinges, the door effectively prevents unauthorized intrusion from outside.

Resistance to insects and dust

The tight-sealing design prevents the intrusion of rats, cockroaches, ants, and other insects into living and working spaces such as warehouses, factories, bedrooms, and offices. This is a preferred solution for protecting health and skin by blocking dust and other harmful elements. The door is also easy to clean, reducing the risk of bacterial and pathogen development.

Sound insulation

EI90 fire-rated steel doors provide effective sound insulation, creating private and controlled environments, making them an ideal choice for factories and offices. This helps establish a refined working environment, enhances productivity, and reduces noise pollution from machinery and external traffic. This factor also supports mental well-being, enabling individuals to work more creatively and efficiently.

Enhanced architectural aesthetics

ADAMCO doors feature modern and aesthetically refined designs, enabling the products to meet diverse practical requirements. Customers can easily find suitable fire-rated steel door solutions for residential buildings, apartment complexes, offices, shopping centers, or supermarkets.
