Fire-resistant plate coatings
Ceilings and fire walls
Composition
The coverings of these ceilings and walls are made of multiple materials:
Alba plaster tile, cardboard plasterboards, fibre-reinforced plasterboards, special fire-resistant boards, fibre-reinforced concrete, rock wool.
Use of the system
For fire protection solutions, certain parts of buildings (e. g. fire compartments - escape routes) must be fitted with fire ceilings or fire walls (load-bearing/non-load-bearing), in way of the fire compartments or inside them, on the load-bearing structures of the building.
We can find these fire-resistant coatings in new buildings or in the event of renovations or reassignments of buildings.
Advantages
- Very good fire protection properties
- Ensure the statics of the building in case of fire
- Several possibilities of choice of materials
- Mechanical shock resistant
- Advantageous aesthetics depending on the choice of finish
- Very good soundproofing properties
AEAI Fire Protection Directive — Load-bearing systems and fire compartments / 15-15en
The fire resistance of the load-bearing systems and components forming the fire compartment must be fixed in such a way as to guarantee the safety of persons and fire-fighting, as well as to prevent the spread of fires to other fire compartments during the defined period of time.
Product feature
Also refer to the fire protection guidelines - Use of building materials /14-15en.
Classification
Resistance EI 30 to EI 180.
Carbon blade coatings
Composition
These fire plates are composed of:
Concrete, glass aggregate, cellulose fibres or synthetic fibres.
Use of the system
In the case of building renovations or reassignments, existing load-bearing structures are insufficiently dimensioned, so reinforcement is necessary and the solution is to glue a carbon fibre fabric to increase the load.
Carbon strips peel off at temperatures between 45 and 90°C, which is why it is essential to protect these strips for the safety of people and the statics of the building.
Two scenarios where they are used for protection: The first one if the reinforced concrete floor is not weakened, but in case of fire its safety curve is insufficient due to the loss of strength of the concrete and its load. Secondly if the safety reserve cannot be respected due to a higher load increase where the floor is weakened by a modification of the static system with a relatively large opening in the floor.
Advantages (depending on insulation choice)
- Very good fire protection properties
- Ensures the statics of the building in case of fire
- Frost and water resistant
- High compressive strength
- High bending strength
- High abrasion resistance
AEAI Fire Protection Directive — Load-bearing systems and fire compartments / 15-15en
The fire resistance of the load-bearing systems and components forming the fire compartment must be fixed in such a way as to guarantee the safety of persons and fire-fighting, as well as to prevent the spread of fires to other fire compartments during the defined period of time.
Classification
Resistance of 30 to 90 minutes. In Switzerland, there is no approval procedure for the usage of glued reinforcements, but fire-resistant products have been submitted to the building technology committee of the Association of Cantonal Fire Insurance Institutions (AEAI) and have been approved.
Fire protection cable trays
Composition
The fire protection elements of the cable trays are composed of:
Concrete, glass aggregate, cellulose fibres or synthetic fibres.
Use of the system
The fire protection elements of the cable trays are installed in vertical and horizontal evacuation routes, technical rooms in certain cases, where the thermal load of the cables exceeds the thresholds allowed by the AEAI standard.
The elements will be glued together and also mechanically fixed with or without a frame to the existing wall or floor.
Advantages
- Flexible, can be manufactured in any size
- Short installation time
- Waterproof and water-resistant
- High load capacity
- Good sound resistance also to impact noise
- Fire resistant EI90
AEAI Fire Protection Directive
In Switzerland, there is no approval procedure for fire protection elements of cable trays.
Classification without examination of the Swiss Fire Protection Directory.
Product feature
Choose the ideal fire protection for your project: either fire from outside the fire protection elements of the cable tray or fire from inside the fire protection elements of the cable tray.
The implementation of fire barriers for cable trays must be agreed with the competent authorities on a case-by-case basis.
Classification
Fire protection cable trays with partitioning function and thermal insulation are classified in fire resistance classes I30 to I120 - E30 to E120.
Coating of pillars and steel beams
Composition
The coatings of these structures can be installed with multiple materials:
Alba plaster tile, cardboard plasterboards, fibre-reinforced plasterboards, special fire-resistant boards, fibre-reinforced concrete, rock wool.
Use of the system
Fire-resistant technical coatings for pillars and metal beams (load-bearing and non-load-bearing) at or inside the fire compartments on the load-bearing structures of the building.
We can find these fire-resistant coatings in new buildings or in the event of renovations or reassignments of buildings.
Advantages
- Very good fire protection properties
- Ensures the statics of the building in case of fire
- Several possibilities of choice of materials
- Mechanical shock resistant
- Advantageous aesthetics depending on the choice of finish
- Very good soundproofing properties
AEAI Fire Protection Directive — Load-bearing systems and fire compartments / 15-15en
The fire resistance of the load-bearing systems and components forming the fire compartment must be fixed in such a way as to guarantee the safety of persons and fire-fighting, as well as to prevent the spread of fires to other fire compartments during the defined period of time.
Product feature
The plate thickness must be defined according to the calculation of the U/A factor and according to the manufacturers' tables.
Also refer to the fire protection guidelines - Use of building materials /14-15en.
Classification
Resistance EI 30 to EI 180.
Boxing return on flap
Composition
These fire plates are made up of two parts:
Concrete, glass aggregate, cellulose fibres or synthetic fibres.
Use of the system
For air conditioning installations the flaps must be installed on the axis of the fire compartmentalization, but in some cases it is impossible to carry out according to the standard and the flaps are offset from the floor or wall. For this reason, it is required to cover the ventilation elements with the same fire resistance as the construction element forming the fire compartment.
The boxing around the ventilation elements up to the fire damper must be carried out according to the state of the art of the system and according to the AEAI standards.
Advantages (depending on insulation choice)
- Very good fire protection properties
- Ensures proper valve operation
- Validated by the state of the art
AEAI Fire Protection Directive — Air conditioning systems / 25-15en
Classification
Resistance EI 30 to EI 90.
Smoke and heat extraction duct
Composition
These fire plates are composed of:
Concrete, glass granulate, cellulose fibres or synthetic fibres or calcium silicate based on Promaxon.
Use of the system
The air used in buildings must be regularly replaced by fresh air for people who live, operate and work there. Thanks to these coatings or smoke extraction channel manufacturing, we can ensure the safety of these people.
For horizontal or vertical ventilation and smoke extraction ducts in the event of a fire, instead of the air supplied or exhausted, no hot gas or smoke can reach other areas, the ventilation ducts are fireproof.
Advantages (depending on material choice)
- High quality fire protection
- Thermal insulation due to its endothermic reaction
- Shock and moisture resistant
- Smoke and hot gas resistant
- Suitable for outdoor and indoor use
- Stability over time
- Respect for the health of installers and users
AEAI Fire Protection Directive — Smoke and heat extraction systems / 21-15en
Buildings, other structures or fire compartments must be equipped with a smoke and heat extraction system sized according to their number of occupants, number of levels, type of construction, location, extent and use.
Classification
Resistance A1, EI 30 to EI 180.
