Thermedia 0.45 - This ready-to-use concrete solution combines both thermal & structural performance and reduces heat loss from buildings through thermal bridges

Thermedia 0.45 is a Lafarge Holcim solution for constructing residential and utility, multi-storey buildings in cities. It combines the structural and insulation properties to construct faster and to fulfil strict thermal regulations. It was solely designed to eliminate thermal bridges between facades, floors and splits (reduction of more than 40%) in the case of thermal insulation from the inside (ITI). Thermedia 0.45 allows replacing traditional construction with thermal brakes to reduce the overall cost and complexity of construction, requires regular formwork and can be placed with minimum energy.

Key features

  • Thermal conductivity coefficient (λ) = 0.45 W/m2K and compressive strength after 28 days (Rc28) = 25 MPa
  • 40% reduction of thermal bridges vs. standard concrete
  • About the same GHG emission vs. standard solution (the calculations saw 2% reduction)
  • 100% recyclable
  • Significant reduction of thermal bridges between facades, floors and splits


  • Up to 15 Euro/ m2 less for the facade construction vs. standard construction (concrete + thermal breakers + internal insulation)
  • Thermedia allows reducing the complexity of construction by providing an insulating and mechanically resistant concrete
  • Thermedia ready-to-use concrete requires the same regular formwork than other traditional concretes
