Compares with wall constructions and weights 

1-scab construction of a wall
 1-scab construction of a wall
In comparison to the needed size of a wall for thermal insulation of ICF to a conventional wall.
  • To achieve a thermal transmittance value of a 37.5 cm thick wall with 0.12 W/(m²K), a 1-scab construction of a wall needs to be at least 65 cm.
  • To achieve at 0.16 W/(m²K) as a well designated coefficient of thermal inductivity the value 0.12 W/(m²K), the wall needs to be already 131 cm thick.
  • At 43.75 cm the ICF wall thickness needs to become even
    157 cm thick.

High complexity and uncertainty factors.

  • Here is the additional exterior damp course consisting of rigid-foam or mineral fibre.
  • The exterior damp course takes over the heat insulation.
  • But through the securing dowels for the insulating boards, gaps through blunt butt joint etc. leaks can develop.
    Consequence: damage of the bricking by thermal bridges.


3-scab construction of a wall

3-scab construction of a wall

Of ICF designed for complete damping without thermal bridges.

  • Nut or nose raster avoid thermal bridges
  • Hot of cold air flow behind the damping is not possible
  • Permanent and intensive conjunction through wire pentameters:
  • The tensile strength is compared to affixed sheet goods more than 100 times higher.

  • Through the ICF reversal-construction system
  • Primarily sticking the damping and then filling the concrete- the construction of a wall becomes - also concerning the saving of time - considerably more cost-effectively.
  • At the same time you get a solid basis using  this massive building technique and appropriate steel inlays according to the default of the structural designer:
  • Earthquakes up to at least seismic intensity 8
  • Storms, like a hurricane, category 5 (Saffir-Simpson-Hurricane-scale)


Primary energy of building materials

Reflecting the energetic situation the production energy should not remain unconsidered. This so called “primary energy content” of building materials consists of

  • the direct need of energy which emerges at the production  at the manufacturing company;
  • the indirect need of energy that emerges at the production process of the raw materials used in the final product;
  • the indirect need of energy which.

The convenient value of poystyrol-rigid foam has been made possible not until the last few years through extensively improvement considering the production method
