Thermally Efficient Steel Lintels



Improving the thermal performance of walls is crucial for energy efficiency in buildings, and addressing thermal bridges like lintels is a key aspect of this. Here
are some methods to achieve better psi values:

  • Thermally efficient lintels that offer a cost effective solution to lowering carbon emissions.
  • Lintels without base plates, no clips or brackets: Eliminating the base plates altogether reduces the amount of material that conducts heat, further minimizing thermal bridging.
  • Each of these methods aims to decrease the psi value, indicating a lower heat loss through the lintels, thereby improving the overall thermal performance of the wall and the building as a whole.
  • Also we can offer a two part lintel system that involves separate lintels for the inner and outer leaf of the wall, effectively creating a break in the thermal bridge between them.
  • This design significantly reduces heat transfer compared to traditional lintels.
