Be it a commercial facility such as a multiplex or residential property such as your home, fire-safety is a must. According to the latest studies, fire outbreaks are the third biggest risk to businesses, highlighting the necessity of prompt fire-safety. While installing fire-rated doorsets is one of the most effective ways to improve the overall fire-safety standards, knowing a few distinguishing factors between a fire-rated doorset and a non-fire-rated door is essential. Continuing on the subject, we present a list of five key differences between a fire-rated doorset and a non fire-rated door. Read on.

1. Composition

A fire-rated door is composed of a high-performance solid particle core with the door frame being made from high-density hardwood or LVL core, depending on the desired range of fire-rating. On the other hand, a non fire-rated door is generally made by pasting wood batons and veneers together; as a result, it cannot offer the fire-retardancy properties offered by a fire-rated doorset.

2. Certification

Fire-rated doorsets come with a plethora of certifications ensuring the fact that the doorsets offer legitimate fire-resistance. For instance, Mikasa’s range of fire-rated doorsets meets BS 476 Part 22, BM Trada, and Q-Mark certifications for fire-safety, making them India’s only true fire-rated doors.

3. Intumescent Seals

Fire-rated doorsets come with intumescent seals attached around the door-frame. In the wake of a fire-accident, these seals expand and help contain smoke and fire for a set period of time. When it comes to non fire-rated doors, one cannot find any such intumescent seals around the door frame.

4. Door Gaps

Unlike normal doors, fire-rated doors have very little gaps around the top as well as the sides of the door. Upon closing a fire-rated door, the gap in the sides is less than 4mm and the gap under the door is around 8mm or less. Leaving little to no gaps in the sides and bottom allows fire-rated doors to control fire and smoke from spreading.

5. Complete Assembly

Fire-rated doorsets are offered as a complete assembly which includes the door leaf, frame, and the necessary ironmongery. As fire-rated doors need fire-proof accessories, the doors are generally sold as an entire unit, unlike a conventional door. Mikasa’s range of fire-rated doors is offered as a completely certified doorset.
