Reaction to fire

The reaction to fire of Kerrock material for the construction sector has been demonstrated through analysis covering its behavior in the initial phase of a fire. Tests were carried out in accordance with the requirements of the European standard EN 13501-1 (Euroclass System). Kerrock panels were classified with a reaction to fire class of B-s1,d0. The tests were performed:

  • at CSI (Certification and Behavioral Analysis Center – Italy) – Classification Report 0589\DC\REA\22_3
  • at ZAG (Slovenian National Building and Civil Engineering Institute) – Classification Report No. P 0942/10-530-4

Fire reaction tests of Kerrock were also carried out in accordance with DIN 4102-1 at HFM TUM (Technische Universität München). Kerrock received a B1 classification for building materials – Test Report B20252.

Kerrock material was also tested for smoke development and toxicity in accordance with Resolution MSC: 61 (67), FTP Code, Annex 1, Part 2. Exova Warringtonfire conducted the testing, and Kerrock meets the requirements of IMO FTPC, Part 2, Section 2.6.1.1 (Smoke) and Section 2.6.2 (Toxicity of smoke) – Report No. 2011-1241-1.

This confirms the suitability of Kerrock material for use in partitions, cladding, or ceilings.

LEED

LEED (Leadership in Energy & Environmental Design) is a leading international system, or program, for evaluating and certifying building design, while promoting best global practices in construction and the use of building products. It helps professionals improve the quality of building products and reduce environmental impact. The green building sector is rapidly growing, and therefore owners and contractors are increasingly recognizing the benefits of LEED certification.
