Fire Proofing

What is the purpose of fireproofing?

fireproofing, use of fire-resistant materials in a building to prevent structural collapse and allow safe egress of occupants in case of fire.

What material is used for fireproofing?

Common materials used include solid lumber, plywood, OSB, Particle board, gypsum board, cement fiberboard, or glass fiber insulation batts.

How is fireproofing done?

The most common way of fireproofing is by spraying low-density fibers or cementitious compounds, called spray-applied fire-resistive materials or SFRM. These sprays can be applied wet or dry, in coatings of the desired thickness, to provide heat resistance to steel.

How many types of fireproofing are there?

The three main types of fireproofing methods are cementitious fireproofing, intumescent fireproofing and firestop fireproofing.

What insulation is fireproof?

Fiberglass insulation is made of glass combined with plastic polymers and is naturally fire-resistant.

Fireproofing Materials

The design codes and standards do not provide any direct indication for the material to be used for fireproofing. The material must be durable and corrosion-resistant. Based on construction practice, the following materials are used as fireproofing materials:

Gypsum plasters

Pyrocrete 241

Mesh

Cementitious plasters

Carbomastic 801(a+b)

Carboguard 890 (a+b)

Carboguard 1340 (a+b)

Carboline 139 (ral 7042)

Fibrous plasters containing either mineral wool or ceramic fibers

Thinner # 2

Thinner # 76

Thinner #25

Thinner # 33

Concrete

Intumescent coatings

Asbestos

Types of Fireproofing / Fireproofing types

In many industrial facilities, to secure any insurance fireproofing is a pre-requisite. On a broad scale, Fireproofing is divided into two groups:

Active Fireproofing

Passive Fireproofing

In case of active fireproofing, human intervention is required for some kind of action to activate the fireproofing system. Whereas, passive fireproofing is planned and designed considering safety plans beforehand. The most common type of passive fireproofing is

cementitious fireproofing

intumescent fireproofing

firestop fireproofing
