LEADS Group have been undertaking projects in the field of fireproofing for more than three years.In every assignment our objective is to ensure that fireproofing systems are applied in accordance with the international codes & standards ,approved designs & specifications & regulatory requirements.
Fireproofing – a passive fire protection measure – refers to the act of making materials or structures more resistant to fire, or to those materials themselves, or the act of applying such materials.
In simple terms, Fireproofing is the application of fire retardant cementitious, fibrous, or intumescent products to bare, unprotected structural steel beams, columns or decks of a building.
Applying a certification listed fireproofing system to certain structures allows these to have a fire-resistance rating. The term fireproof does not necessarily mean that an item can never burn. It relates to measured performance under specific conditions of testing and evaluation. Fireproofing does not allow treated items to be entirely unaffected by any fire, as conventional materials are not immune to the effects of fire at a sufficient intensity and/or duration.
Fireproofing is extremely serious and critical to Life-safety and Property-protection, therefore, only design listed fireproofing systems be applied.
Main Types of fire proofing are:
Gypsum plasters : The industry considers gypsum-based plasters to be “cementitious”, even though these contain no Portland, or calcium aluminate cements. Cementitious plasters that contain Portland cement have been traditionally lightened by the use of inorganic light weight aggregates, such as vermiculite and perlite.
Cementitious Plasters: Gypsum plasters have been lightened by using chemical additives to create bubbles that displace solids, thus reducing the bulk density. Also, lightweight polystyrene beads have been mixed into the plasters at the factory in an effort to reduce the density, which generally results in a more effective insulation at a lower cost. The resulting plaster has qualified to the A2 combustibility rating as per DIN4102.
Intumescent Coating: An intumescent is a substance that swells as a result of heat exposure, thus increasing in volume and decreasing in density. Intumescents are typically used in passive fire protection and require listing, approval and compliance in their installed configurations in order to comply with the national building codes and laws.
