Structural Steelwork Protection
Current regulations require certain elements of the building structure to have fire resistance. Fire resistance testing on structural steel members have shown, that by incorporating a proprietary fire protection system, the ability of the structure to resist fire will be greatly enhanced dependent upon the particular system chosen.
Boarded Fire Protection Systems
Materials we use
- Glasroc F board encasement
- Beam Clad
- Fire line board
Boarded fire protection systems offer a non-combustible and cost efficient method of providing up to 240 minutes fire protection to structural steelwork. As the original means of affording structural fire protection, this method has seen major developments in the types of boards available today.Boarded fire protection systems can be durable, resistant to water and beneficial to acoustic performance. Certain fire boarded systems are able to accept decorative applications, such as paint or plaster, providing an aesthetic finish without the need for further preparation.
Intumescent Paint Systems
Thin film applied Intumescent paint is a fast method of providing up to 120 minutes fire protection to structural steelwork. Intumescent coatings provide an appearance similar to that of paint, with basic to high gloss finishes now available. At ambient temperatures Intumescent paint systems remains stable. However in a fire condition, the increase in temperature activates a chemical reaction which then causes the intumescent coating to expand many times its original thickness.
This expansion provides an insulating foam-like coating or "char". It is this "char" that provides the fire protection to the steel work which, in some instances, can be up to 50 times its initial applied thickness. Therefore, secondary casings applied to the steel members must allow for expansion to ensure the intumescent paint system performs correctly.
Fire Compartmentation Systems
The spread of fire can be restricted by sub-dividing buildings into a number of discrete compartments. These fire compartments are separated from one another by compartment walls and compartment floors made of a fire-resisting construction which hinders the spread of fire.
Approved document J, Combustion appliances and fuel storage systems, defines a fire compartment as:
ÃÂÃÂ a building or part of a building comprising one or more rooms, spaces or storeys constructed to prevent the spread of fire to or from another part of the same building or an adjoining building. (A roof-space above the top storey of a fire compartment is included in that fire compartment.) A separated part of a building is a form of compartmentation in which part of a building is separated from another part of the same building by a compartment wall. Such walls run the full height of the part and are in one vertical plane.ÃÂ
Fire compartmentation/Fire stopping:
- Prevents the rapid spread of fire which could trap the occupants of a building.
- Reduces the chance of fires growing and creating a danger to occupants, fire and rescue services, and people in the vicinity of the building.
- Limits the damage caused to a building and its contents.
The degree of sub-division that should be provided by fire compartmentation will be dependent on:
- The use of the building.
- The fireload in the building.
- The height of the building.
- The availability of a sprinkler system.
We offer, design, supply and installation of Thermal Soffit Insulation systems to Service Yard, Car Parks or Residential Basements where certain ÃÂuÃÂ value criteriaÃÂs are to be met and achieved.
Soffit Insulation Systems offered consist of:
- Direct Fixing Systems, i.e. to Concrete Soffits; Structural Metal Deck
- Bespoke MF Grid Systems
There is an increasing requirement for the thermal upgrading of semi-exposed concrete decks both in the conversion and refurbishment of existing buildings and in new build constructions in accordance with Part L, of the Building Regulations.
