VENTILATION CHIMNEY SYSTEMS SKW CJ BLOK® LECA concrete ventilation hollow blocks PW CJ BLOK® are intended for building gravity ventilation systems for air exchange in residential, public and industrial premises.

Ventilation ducts made of CJ BLOK® ventilation hollow blocks of high fire resistance have the ability to prevent the spread of fire from one room to another, when exposed to fire from inside or outside the duct.

Ventilations made of CJ BLOK® hollow blocks are referred to as fire-resistant ducts. This feature allows them to be used in projects to ensure specific fire resistance in accordance with the PN-EN 13501-2 standard.

CJ BLOK® fire resistant ventilation ducts are classified according to the following fire resistance classes:

  • ducts made of hollow blocks PW 1/25:    EI 120
  • ducts made of hollow blocks PW 2/36, PW 2/38: EI 90
  • ducts made of hollow blocks PW 3/52:    EI 120
  • ducts made of hollow blocks PW 4/50:    EI 120

The numbers 90 and 120 indicate the degree of the fire-containment capacity, given in minutes.

 

Advantages of CJ BLOK® ventilation hollow blocks:

  • Simple and quick assembly. 
  • High compressive strength. 
  • High fire resistance. 
  • No masonry required. 
  • Suitable for use with CJ BLOK® chimneys.
