Fire Protection Systems for Wood and Concrete

Presentation Rudolf Hensel GmbH and Audax-Keck GmbH

A number of fundamental requirements

of fire protection are specified

in the Building Regulations

which are different in any country


• Means of escape

• Internal spread of flame to linings

• Structural Integrity of the building

• Fire compartmentation

• Access and facilities for emergency services

• Reduce the rising cost of insurance polices

• Protect capital investment

• Reduce the possible risk to the fire fighters


• Building Codes require that steel is protected to ensure loadbearing strength


• Building Codes require that steel is protected to ensure loadbearing strength

• Temperatures rises from 20°C to more than 1000°C

Coating Systems

Advantages • Ideal where the exposed profile of the steel

is a feature of the building design • Only system suitable for castellated and

cellular beams where the openings are used for services

• Light weight compared to other systems


Coating Systems

Advantages • Thin film systems reduces the amount of

space used • Up to 10 times faster to apply than boarding

systems • Decorative topseals available • Fibre free, no dust • Easy to clean and maintain


Coating Systems

Disadvantages • Quality checks required • Primer compatibility checks required • Drying times • Masking may be required to surrounding

areas • Skilled labour application for best results


Coating Systems

Intumescent coatings are the most efficient coatings for

30, 60, 90 and 120 minutes retardation time.

Now also successfully tested

up to 180 minutes!

A Fire Protection Coating is a perfect fire protection for simple steel constructions as well as for complex modern steel constructions.

The fire protection system reacts to the heat

and produces a temperature insulating char

protects the steel construction against critical temperatures

saves valuable time for evacuation and firefighting

Principle of Fire Protection Coatings

Intumescent Coatings

Principle (lat. intumescere = to foam)

General composition of an intumescent coating: 1) Carbon source 2) Acid donor 3) Blowing agent

Formation of a voluminous insulating protective layer by developing a carbon-rich foam and a concurrent expansion.

The intumescent foam attains a thickness 10 to 100 times that of the originally applied coating and insulates the substrate material by its low thermal conductivity.

Steel Fire Protection Systems Then and Today


> 1970 Architects recognize benefits of

fire protection paints for steel IC solvent based For open profiles Fire resistance classification R30 High film thicknesses (2-3mm) Mainly for indoor use

> 1980 Realisation of huge construction projects with steel-,

anti-corrosion- and fire protection coatings Launch of single-layer systems with less solvent

contents IC still mainly solvent based Improved colour designs due to top coat

developments

> 1990 Launch of water-based IC Fire resistance classification

up to 60 Minutes (R60) Indoor use without top coat More efficient formulas due to

a new generation of raw materials: improved weather-resistance low coverage rates

> 2000 First approval for a solvent-based IC with

fire resistance classification R90 First approval for water-based IC Construction projects with high surface

requirements (smooth or textured) Decorative steel fire protection systems

become more important

> 2010

R90 steel fire protection systems are more attractive than plaster or panels

Film thicknesses of 2 – 4 mm for R90/R120 (for plaster or panels ≥ 20 mm are necessary)

DekoPaint-Standard (2010) requires very low VOC-emissions

Growing demand of „Green Building“, sustainable building and LEED


Modern steel fire protection systems

provide maintenance-free long-term protection

protect against corrosion

are aesthetic due to low film thicknesses

provide long fire resistance up to three hours (R180)

protect filigree constructions too

are cost-effective

meet relevant standards worldwide

are sustainable


Improvement of Constructions

Common tasks

• Optical attractive design

• Weight- and cost-optimized construction

• High-quality surfaces

Result

• Visible circular and rectangular hollow sections

• Thin-walled steel sections

• Inappropriate colour shades

Challenges

• Fire protection not duly taken into consideration in the planning stage

Source: Rudolf Hensel


Background

• Heat conductivity of open profiles is better than heat conductivity of circular and rectangular hollow sections

• Partially no approvals for circular and rectangular hollow sections

• Higher film thicknesses for filigree profiles required

Consequences for fire protection

• High film thicknesses for hollow sections required

• Additional work steps to reach the necessary film thickness

• Additional costs

• Big influence on the optical appearance of the steel sections

Conclusion

• Consideration of fire protection in the earliest planning stage will lead to cost-effective solutions combined with a high level of fire safety and surface appearance.

Thermal absorption of different steel profiles

• Massive profiles heat up slowly

• Critical temperature is reached slowly

• Low film thickness of fire protection coating is sufficient

• Filigree profiles heat up quickly

• Critical temperature is reached quickly

• High film thickness of fire protection coating is necessary


Section Factor (High) Hp/(Low) A

Section Factor (Low) Hp/(High) A

• Low fire resistance • Greater protection required • High film thickness

• High fire resistance •Less protection required •Low film thickness

The Life Cycle Inventory (LCI) includes information regarding resource consumption, e.g. energy, water and renewable resources as well as information regarding emissions in air, water and soil. The Life Cycle Impact Assessment (LCIA) is based on the results of the LCI and specifies the concrete environmental effects. These are: Greenhouse effect Destruction of the ozone layer in the stratosphere Acidification of water and soil Eutrophication Formation of photochemical oxidants Exhaustion of fossil energy resources Exhaustion of mineral resources

Reference – HUGO BOSS AG, Metzingen – with HENSOTHERM® 420 KS

A new administration building for Hugo Boss AG has been build on the campus of the headquarters in Metzingen. With this building the overall concept developed in the year 2000 has been continued. The construction site started in February 2012. In May 2013 the building was handed over to the user. Certified according to DGNB Gold Standard IWS Award 2013
