Insulation Specification

  • Thermal Conductivity Value : Amount of heat (W) passing through a material having surface of 1 M2 and thickness 1 M in order to rise temperature by 1oC . Units are W/m K
  • K value (Insulation Value) : Thermal conductivity divided by thickness of the material [ W / m2 K]
  • U value (Total Insulation Value) : Also known as Overall Heat Transfer Coefficient determined by the insulation value of the various materials forming the panel . [ W / m2 K ] , KCal/m2 h oC , BTU/ F t2 h oF
On Continuous System   Density K value
   Polyurethane (PUR) 35-40 Kg/m3 0.022 w/m2K
   Polyisocyanurate (PIR) 40-45 Kg/m3 0.022 w/m2K
   Mineral Wool / Rockwool 80-150 Kg/m3 0.04 w/m2K
   Expanded Polystyrene (EPS) 16-24 Kg/m3 0.035 w/m2K
