From the Biederen Bungalow to Modern Detached House: Bungalow converted

In the 1960s bungalows in Germany experienced their heyday. The single-storey residential opportunities have often lost significantly at charm over the decades - that does not have to be! How to rebuild a bungalow and help it to help him bloom in our guidebook.

Save energy - façade insulation

One of the most important points in the conversion of an old bungalow to modern living space is the thermal insulation. Before the first thermal insulation ordinance came into force in Germany in 1977, it was common practice to build external walls with a U-value of only around 1 W / m²K. Compared to a wall erected in 2014, this means about 5 times more heat loss.
This creates a number of other problems:

  • In any case, bungalows do not show ideal heating behavior, due to the lack of storeys, the enclosed space is not optimal.
  • Poorly insulated exterior walls can quickly lead to mold growth.
  • A comfortable living environment is difficult to achieve because cold walls are perceived as uncomfortable - even if the room temperature itself is high.

When it comes to facade insulation, you are obliged to observe the new Energy Saving Ordinance (EnEV) and to establish modern insulation values.
Therefore, if in doubt, always consult a specialist company in order to choose the right insulation material in the right material thickness.
When insulating the facade from the outside, proceed as follows:

  • Thoroughly clean the outside wall. All surfaces must be stable, level, dry, free of grease, dust and frost. Repair damaged areas with plaster or mortar (€ 7.79 at Amazon *). In the case of highly absorbent substrates, you should prime the facade with a primer.
  • Attach base profiles for the external insulation. Make sure to attach the profiles 30cm above the top of the ground.
  • Mix the right adhesive mortar for your insulation boards.
  • Apply the adhesive all around the plate and also place adhesive dots inside the plate. Approx. 60% of the board should be covered with glue.
  • Put the panels on the facade. Work with an offset of at least 20 cm between the rows. Work on house corners with a small overhang and interlock the insulation with one another.
  • Work particularly carefully on wall openings such as doors and windows.
  • Anchor the insulation boards with plate anchors along the long edges.
  • Apply a suitable adhesive spatula to the external insulation.
  • Work a crease-free reinforcement mesh on the facade.
  • Now you can plaster the facade again.
