The first passive house with cellular glass walls

logo_smallA typical saying is that passive house walls with cellular glass are becoming too thick due to the moderate thermal conductivity. Like most sayings, the truth is something else, it is founded on conservatism. Indeed, Denmark has its first cellular glass passive house and the next one is underway.

The house is a Clean Tech Block result, which is already mentioned in previous blog. Clean Tech Block is a project from  Gråsten Teglværk, the University of Aalborg and the University of Ljubljana.

The choice for cellular glass is obvious:

  • air tight (passive house standard)
  • vapour tight and so no risk for humidity accumulation
  • free from rodents, ants and other animals.
  • long if not eternal lifetime
  • ecologic, according to the Swiss even the most ecologic thermal insulation
  • non-combustible
  • self-supporting, no deformation due to mechanical load or temperature
  • almost the same thermal expansions as the other minerals used in the building
  • not expensive if produced by direct foaming of recycled glass.

In our opinion, this is a major step in cellular glass building.
