Insulating materials

Insulation materials are building materials that have a low bulk density and thermal conductivity. Static air inside the building materials minimizes heat and cold loss, thus creating a stable indoor climate inside the building.

More about insulation materials

Air is a poor conductor of heat. This property can be exploited with thermal insulation materials. Air is trapped in the pores of the insulation material.

Typically, higher-density fabrics conduct heat better than low-density fabrics. Therefore, metal components are good heat conductors and are often responsible for insulation losses.

equivalent to 2 cm Insulation material:

  • Lightweight concrete blocks: 6.0 cm
  • Softwood: 6.5 cm
  • Porous bricks: 8.0 cm
  • Straw clay: 23.5 cm
  • Perforated bricks: 29.0 cm
  • Clinker masonry: 90.0 cm
  • Reinforced concrete: 105.0 cm
Planning notes

Various insulation materials are suitable for different applications. Exterior insulation, for example, must not absorb water, otherwise the insulating effect can be reduced.
