The mcr Silboard system consists of innovative fire-protection calcium silicate boards designed for:

  • building self-supporting EIS120 ventilation and smoke exhaust ducts
  • building cable ducts ensuring an uninterrupted electrical power supply or signal transmission for 30, 60, 90 and 120 minutes
  • fireproofing reinforced concrete construction components, reinforced with carbon fibre strips and cloths, in up to 120 minutes depending on the critical temperature of the adhesive applied
  • fireproofing steel structures, in classes R15-R180 (one layer) and R15-R360 (two layers)
  • building non-bearing fire division walls in classes EI 120 and EI 240

  • board thickness of no more than 40 mm – the thinnest insulation layer available for EIS120 ducts
  • high mechanical strength
  • easy to work; quick, simple and clean installation
  • smooth and clean surface of fire protection insulation
  • no need to insulate steel brackets supporting ventilation and smoke exhaust ducts and cable ducts
  • no toxicity, no health-hazardous substances
  • total resistance to biodegradation (fungi, bacteria)
  • weather exposure category Y – indoor applications and partial exposure to weather conditions as per ETAG 018-4
  • density: 550 ± 15% kg/m3
  • non-combustible product, reaction to fire class A1 as per EN 13501-1
  • heat transfer factor λ=0,095 W/(m·K)
  • available sizes: 800 x 1250 mm
  • thickness: 20, 30, 40, 50 mm
