Fire Doors are important for stopping the spread of fire and smoke in a building. They are manufactured along with specific standards. It must have certain points to fulfill its purpose, such as fire resistance, minimal spacing between the door and surrounding walls, smoke sealing systems, and a Self-operating closing system. The things that need to be checked are given below:

Door Size

Typically, the size of Fire Rated Doors in Bangladesh are 1000 X 2100 mm; 900 X 2100 mm; 1100 X 2100 mm; 1100 X 2400 mm; 750 X 2100 mm; 900 X 2400 mm. The depth can vary depending on the material. However, you can have doors that are much taller. These sizes are commonly available and used in various commercial and residential buildings to meet fire safety regulations and requirements. However, it’s essential to check with the specific Manufacturer In Bangladesh or Supplier In Bangladesh. There are some variations in sizes may be available depending on their product offerings and customization options. High-quality residential fire rated doors for sale, providing peace of mind and enhanced safety for homeowners.

Thickness

The thickness of Fire External Door can vary depending on their fire resistance rating. The specific building regulations they need to adhere to. Generally, Fire Resistant Door come in different thicknesses to meet different fire rating requirements. The thickness of Doors varies according to its quality. For example, FD30 (30 minutes) doors are usually 44/45mm thick, as opposed to the standard door thickness of 35/40 mm. While FD60 (60 minutes) doors, most commonly used in commercial settings, are normally 54mm thick. Specially constructed doors can have a rating of 4 hours or more. The thickness of these doors will be adjusted accordingly to meet the specific fire rating requirements.

Material

Fire Glazed Doors are constructed of materials that work together to slow or stop the spread of flames, smoke, and, in certain applications, radiant and conductive heat transfer. Common materials of Fire Doors include wood, steel, fiberglass, and fire-rated glass, or a combination of these materials. Fire-resistant doors are made with special fireproof materials like glass, steel, gypsum, vermiculite boards, and even wood! These materials can resist fire for a minimum of 20 minutes to up to 90 minutes. It can provide enough time for people to evacuate the place. They are installed as Fire Exit Doors, like staircases and corridors, etc.

Composite

Fire Proof Door Composite refers to a type of Fire Door that is constructed using composite materials. Composite materials are made by combining two or more different materials to create a single material with enhanced properties. It often offers superior strength, durability, and fire resistance compared to individual materials. The use of composite materials in Fire Doors allows manufacturers to create doors that meet specific fire rating requirements. It also offering other benefits such as better insulation, reduced weight, and improved resistance to wear and tear. These doors are commonly used in various commercial and industrial settings where fire safety and high performance are essential considerations.

Design

Fire Door Design refers to the aesthetic and functional aspects of a Fire Door. While Fire Doors are primarily designed to provide fire resistance and contain the spread of fire and smoke in a building. Their design can also encompass various elements to complement the overall interior or exterior appearance of the space. A fire can engulf even a massive building in just a few hours. Instead of taking chances, it is better to invest in firefighting doors. There are many designs in doors, such as Designer Doors, Fire Oak Doors, Steel Door Designs, Wooden Door, Office Door Designs, Fire Rated Entry Doors, Sliding Doors, Bedroom Door Designs, Fire Glass Doors, Fire Rated Garage Door etc.

Fire Rating

A fire resistance rating for Fire Doors generally means the duration for which a passive fire protection system can withstand a standard fire resistance test. This can be quantified simply as a measure of time. It can involve other criteria, involving evidence of functionality or fitness for purpose. Fire-rated doors undergo endurance tests where the sample is exposed to extreme heat up to 1925 degrees F for the maximum rating of 180 minutes. If the door remains in the frame with no through openings and limits flames. It is certified with a resistance rating of 20/45/60/90/180 minutes. For those seeking fire-rated glass doors, Dhaka offers a variety of options to ensure both safety and aesthetics in their purchase.

Durability

Fire Door durability is a critical aspect of its performance, ensuring that the door maintains its integrity and fire resistance over time. As Fire Doors are designed to contain and resist the spread of fire, their durability directly impacts their effectiveness in protecting lives and property during a fire emergency. Fire doors are made to be fire-resistant so they can contain a fire for a certain period of time. The time period can range from twenty to ninety minutes, depending on the quality and the part of the building that is burning. There are several tests for fire resistance of record protection equipment like Class 125 Rating, Class 150 Rating, Class 350 Rating. Leading fire-resistant door manufacturer in Bangladesh, providing high-quality doors designed to withstand fire and protect lives and property.

Fire Protected

Fire External Doors are constructed of materials that work together to retard or stop the spread of flame, smoke, and, in certain applications, the transfer of radiant and conductive heat. Common materials include wood, steel, fiberglass, and fire-rated glass, or a combination of these materials. In application, Residential Fire Rated Doors work in conjunction with surrounding passive fire protection systems to provide around-the-clock defense against fire and enable safe and unobstructed passage out of a building. When installed properly, Fire Doors will not combust or fail for the duration of their fire rating (in the average fire). Standard fire ratings vary, typically ranging from 20 to 180 minutes depending on code criteria. Fire-rated doors are required to be self-closing and positive latching. They must remain closed during a fire to protect the means of egress.

Compression

Fireproof Doors can be made with a combination of timber, steel, gypsum, and aluminum. They can also have windows, which are made from borosilicate or ceramic glass (both of which offer higher fire resistance than standard glass), and may contain an anti-shattering wire mesh. A gasket that compresses too much or too little will not form a proper seal. The ideal compression percentage is 40, the maximum is 50, and the minimum is between 10 to 15. The price of Fire Rated Doors in Bangladesh can vary depending on factors such as the fire resistance rating, material, size, and brand.

Chemically Treated

To achieve fire ratings and supplemental life safety and security ratings, fire-rated doors undergo rigorous tests conducted by independent laboratories. These doors are typically filled with more resistant filler material like gypsum. Hollow steel doors can be filled with gypsum as well. Vermiculite and other aluminum or metal panels can be added to wood doors for further fire resistance and to meet hygiene requirements where applicable. All MS sheets are chemically treated before assembly in a highly equipped chemical treatment plant.
