Understanding Mikasa’s Fire-rated Doors

fire doors and doorsets from Mikasa Doors

Fire safety is a major concern in commercial and industrial spaces, as well as multi-occupancy residential spaces. According to a study conducted in 2022, about 1.6 million fire accidents took place in India in 2021, in which more than 27,000 people lost their lives. While the construction layout can’t be changed once completed (unless remodelled), installing fire doors and doorsets is an excellent way to protect people and property during fire outbreaks. Mikasa, from the house of Greenlam Industries, is a trusted name when it comes to providing fire doors and doorsets that are made in compliance with various global fire safety standards.

Reasons To Install Fire-rated Doors

There are several reasons to install fire-resistant doors. These include:

Fire Safety is Essential

A fire outbreak in occupied spaces can maim or kill people and damage property. Installing fire doors and doorsets is a perfect safety measure as they delay the spread of fire and smoke, allowing the occupants to escape and the emergency services to respond to the incident.

Fire Doors can withstand Physical Damage

Fire-rated doors are larger and heavier than regular doors, which makes them extremely tough and able to withstand acts of vandalism. Apart from retarding flames during a fire outbreak, they also act to protect residential and commercial spaces from burglars and other potential threats.

Protection from Toxic Gases

During a fire outbreak in occupied spaces, it’s not just the flames that cause loss of lives, as the release of toxic fumes can also make people choke and faint. A fire exit door, in such a situation, can prevent toxic fumes from propagating to other rooms or spreading across the hallway. This makes fire-rated doors an ideal choice for spaces such as restaurants, hotels, stadiums, and shopping complexes.

Elements of FR Doors

What sets fire-rated doors apart from regular doors is their construction and the elements that constitute them. Some of the components of Mikasa fire-rated doors include:

  • Core: Mikasa’s fire-rated doors come with a highly stable core, which is made from a “five-layer density” particle board with a density of 620 to 850 kg/m3.
  • Wood Lipping: We provide a matching hardwood lipping that comes in different thicknesses of 3/6/10/12 mm, which helps in properly sealing the door leaf from all sides.
  • Frame: Mikasa’s FR door frames come in two types – Rebated (made from solid hardwood) and Engineered (LVL, MDF, or solid hardwood) frames, which have a minimum density of 640 kg/m3.
