摘要

The gap is cavity walls between a heat insulating inner shell and a brick wall outer shell is maintained by distance pieces which help to create a barrier against moisture, to act as heat insulation and to retard the diffusion. To prevent mortar during the building of the outer wall from falling into the intended gap, it is suggested to erect a mortar guard screen on the brick wall side. The brick wall shell can now be built in one fast non-stop operation.
