Where to Apply


Ingeborg – Calcium silicate board is recommended for applications where conforming to the high standard fire regulator by the relevant Building and Fire Authority is required. Such applications would include:

  1. Fire Rated Duct – Mechanical ventilation systems are used to extract vitiated or polluted air from a building
  2. General Building Services – Smoke extraction is the evacuation from a building of products of combustion
  3. Wet/Dry Riser – Kitchen exhaust ductwork presents a particular hazard, in that combustible

Lafire Asia Pte Ltd understands the importance of fire protection systems in a building. To address major issues like fire protection and the effectiveness of protective measures, our dedicated team went through 5 to 6 years of research and progress and developed Ingeborg. Besides saving lives in the event of fire outbreak. Ingeborg also reduces the rising cost of insurance policies, protects capital investments and reduces the possible risk to the firefighters.

Ranked number 2 worldwide in providing fire protection system, Ingeborg is a high-performance fire rated calcium silicate board that serves as one of the alternatives to other fire rated board protection system in the building industry.

Complying with Singapore Civil Defence Force (SCDF)’s regulation requirement, Ingeborg is lighter and thinner as compared to the spray system and the intumescent system available in the market, making it a more superior product. It is noncombustible, engineered calcium silicate board.

Fire Rated Duct

Mechanical Ventilation System

Mechanical ventilation systems transmit fresh air using ducts and fans, without purely depending on air via tiny openings in walls. The necessary fans and conditioning equipment are generally located in separate plant rooms, often in a very large, extend throughout the building, penetrate compartment walls and/or floors and have openings in every space through which it passes.

In the absence of fire precautions, ventilation ductwork furnishes a route by which fire, smoke, and toxic gases are enabled to escalate through a building.


Smoke Extraction System

The main objective of a smoke extraction system is to avert danger, i.e. to save lives and to protect property. The smoke extraction system facilitates the escape of the building occupants and assists firefighters in locating the actual location of the fire and extinguishing it.

If the ductwork is incorporated in a smoke extraction system is wholly contained within the fire compartment, it must at least be capable of resisting the anticipated smoke temperatures generated during the development of a fire. These will generally be lower than the temperatures specified in BS 476: Part 24, which are intended to represent a fully developed fire. However, if the ductwork penetrates a fire resisting barrier, it must also be capable of providing the relevant fire resistance in a test to Part 24. Further clarification of the fire testing requirements for these two different situations is provided in Section ‘5’ of this document ‘Standard Fire Tests’. In view of the importance of maintaining the design extraction rates during a fire, Part 24 also imposes an additional requirement on smoke outlet ductwork (i.e. the retention of at least 75% of its original sectional area during the test)

Car Park and Kitchen Extraction Systems

Car parks and non-domestic kitchens are required to have separate and independent extraction systems, because of the polluted nature of the extracted air. As BS 5588: Part 9/BS9999, recommends that fire dampers should not be installed in extraction ductwork serving car parks or kitchens, any duct or ductwork penetrating fie resisting barriers should be fire resisting.

Kitchen extraction ductwork should be subjected to regular safety checks to prevent any hazards. A fire in an adjacent compartment through which the ductwork passes could, therefore, initiate a fire within the ductwork which, in the absence of fire dampers, might jeopardise the safety of the kitchen occupants. As a result, BS 476: Part 24 sets an additional requirement, (i.e when tested as duct A against external fire) the internal surface of the ductwork within the furnace must meet the insulation criteria. It is also essential that this particular type of ductwork is provided with access for cleaning, at distances not exceeding 3m.


Dual Ventilation / Smoke Extraction System

These systems serve as a conventional ventilation system under normal conditions but are converted to a smoke extraction system in the event of a fire, thus providing an economical dual system.

Fire Rated Duct
General Building Services

British Standard 476 Part 20:

For the provision of fire resisting constructions to cable ducts in general building services in accordance with the performance criteria of BS 476: Part 20 and AS 1530: Part 4. As no specific British Standard exists for such applications, Prompt constructions have been tested in accordance with the criteria of German. The British Standard BS 476: Part 24, and appraised to BS 476: Part 2.

The appraisals include an allowance for both internal and external. The integrity and where pertinent the insulation performance of the enclosure, and any penetrations through compartment walls and floors, is measured.

Circuit integrity of electrical cables or the ability of the service to function are not measured and do not constitute part of the failure criteria.

Wet/Dry Riser



Protection to fire-fighting system i.e sprinkler, rising mains, hydrant etc. An Individual Standard for the wet & dry riser is required in Singapore Fire Safety Bureau. The fire resistance test procedure is described in FSB/PSB/001/00 dated 8 November 2000. This test procedure was adopted specially for the needs in Singapore for testing the fire resistance performance of steel pipe for rising main. In a building, piping for rising main may run through the compartment. It is a concern for Fire Safety and Shelter Department that such piping for rising main need to be adequately protected. Otherwise, in the event of a fire, the piping may not only collapse, reducing the water pressure at the fire-fighting point but will also heat up the water conveying through it for fire-fighting by firemen. The water may reach a stage of boiling and scald the firefighters in the action of releasing the water for fire-fighting. This test procedure was written to facilitate the testing of fire resistance performance of steel piping for rising main. It excludes piping containing fuel and gases. The water boiling point temperature of 100°C is used as a reference. The cladding of the steel pipe is expected to be able to insulate the piping. It is felt that the external surfaces of the steel pipe, on the fire side, shall maintain a temperature not exceeding 75°C above the initial temperature and that on the unexposed side, measured on the cladding, not exceeding 180°C above initial temperature. The test is conducted with air as a medium in the pipe. With water, heat losses from the pipe are expected to be higher, thereby making the test less onerous. The fire resistance performance of the system is based on the integrity and insulation criterions for the unexposed face and the insulation criterion for the exposed face to the fire.
