Home / Architecture / FACADE INSULATION

A property consists of several parts. For example, you have a roof, facade, floors and walls. It is important that your home is energy-efficient and a good insulation of your house determines a lot. There are endless possibilities in terms of finishes and design on the facade.

To go deeper into the facade insulation you first have to know what it exactly is. The word says it all, it is the insulation of the facade or external walls. An important role of the insulation is to reduce energy consumption. This is often the main reason for making the costs. In addition to the insulation itself, it also beautifies the outside of the house. This has a lot of influence on the value. Cold bridges and false drafts are easily eliminated by the insulation, just like mold formation that will rarely or never occur on a well insulated outer wall.


There are many materials that are used for the insulation of facades. The most used is polystyrene plate. It is lightweight and therefore easy to place. It is also easy to cut to size and can even be placed in difficult spots. Furthermore, stone wool and cellular glass plates are also widely used materials. Stone wool has a high compressive strength and glass sheets are very vapor-tight. PUR foam is another frequently used material that is sprayed in liquid and expands quickly, so that a space is easily filled.

Thicknesses and adhesion

The facade insulation does not have any negative influence on the habitable space of your home and therefore you can easily place it a little thicker. Be careful not to cross the dividing line, though.

Each material has its own dimensions. Glass wool needs at least 4 centimeters of cavity width and PUR or polystyrene at least 3 centimeters. The track width plays an important factor in determining which material you choose.

There are 2 ways of attaching the insulation. It is either stuck into place or mechanically fixed. The choice depends on your home and the construction of the outer wall.

Finishing after insulation

  • Plastering, one of the cheapest and simplest ways
  • Stone strips, thin strips of sawed brick
  • Wood, preserved wood is widely chosen (thermowood or tropical wood)
  • Metal or plastic, is widely used in modern homes with unique character
  • New exterior wall, the most costly solution
