Damming the clinker façade - what can you do?


Clinker facades provide excellent and durable weather protection for the building. Unlike plaster facades, however, the subsequent insulation of a clinker façade is problematic throughout. The possibilities for this are described in detail in this article.

Construction of clinker facades

A clinker façade is usually constructed with two shells. The clinker facade represents a facing wall before the actual masonry, and connected to it via so-called air layer anchor. The intermediate space may already be insulated, but is usually uninsulated in old houses.

Possibilities for the insulation of clinker facades

Overall, there are several basic options for insulating clinker facades:

  • Removal of the front brickwork (worst option, should be avoided if possible)
  • Insulation on clinker (almost always problematic)
  • Einblasdämmungen

Each of these methods brings with it their specific problems that must be considered and avoided if possible.

Removal of the clinker facade

A removal of the high-quality (and once expensive) clinker façade does not really make sense for an insulation. In addition, unreasonably high costs would have to be expected. As a rule, there is another option for every house to insulate the walls, where the clinker façade can be preserved.

Insulation on clinker

Basically, this is possible, but due to the air gap in the interior between the two masonry layers, the insulation will not be particularly effective.

Einblasdämmungen

If the gap between the two masonry parts is uninsulated, insulation of this area is often a very efficient and cost-effective solution.

Small holes are drilled or individual cobbles removed, and the entire space is then filled with insulation material. This happens under high pressure, so that the gap is completely filled. If, with a sufficiently wide gap, insulating material of at least the quality 0.40 is used, in many old houses even the values ​​demanded by the EnEV can be achieved in this way.

Possible problems:

  • Air layer anchor (these represent a thermal bridge)
  • so-called trickling (can be caused by leaks in the area of ​​the facade, trickling insulation material emerges)
  • larger hollow layer present (can be filled with fibrous insulation material, is also cheaper)

Tips & Tricks

Everything that was said in this post refers to real clinker facades. Simple veneering of the wall with straps or so-called KS veneers is another matter.
