The European Association for External Thermal Insulation Composite Systems (ETICS) is the umbrella associaton of

  • 11 national ETICS associations;
  • 4 European associations of leading suppliers

(insulation materials); and

  • 1 supporting company member.

EAE represents about 85 % of Europe‘s ETICS market.

Reaction to Fire – historical development

  • Increasing insulation thickness

– Before 2005 insulation thicknesses > 100 mm rare – New energy legislation + increasing energy costs: increasing average thicknesses

  • ETICS industry (2006)

– Series of tests to further improve fire safety – Large-scale tests and natural tests (real estates)

  • Result

– Introduction of fire barriers to ETICS with combustible insulation

REACTION TO FIRE WITHOUT FIRE BARRIERS

  • Increasing pressure inside the ETICS

(heated air, pyrolysis gas)

  • Pyrolysis gas escapes through the

rendering

  • Organic content of rendering burns
  • Lintel deformation

  • Windows: 0.9 m (1.7 m x 1.4 m)

Fire load:

  • 375 kg (resp. 475 kg) wood plus 40 – 50 l Isopropanol
  • Equals 723 – 772 MJ/m2

Conclusion

slide-43
SLIDE 43

ETICS and Reaction to Fire ● European Fire Academy: Round Table Frankfurt ● 27/06/2013 ● Ralf Pasker 43

Test results show:

  • Organic content of render systems burns in a very

limited area of the facade and does not support vertical or horizonal extension of the original fire

  • Original flame is not enlarged significantly
  • No or limited risk of droplets

„Approved ETICS properly installed and maintained are safe in use“ (German parliamentary commission involved in investigation of fire safety of EPS-ETICS)

  • Further tests regarding reaction to fire of plinths
  • Evaluation of improvements on construction sites
  • ETICS industry takes fire safety seriously
  • Adaption of latest results
  • Open for exchange of experirence
