Styrofoam as thermal insulation for the inside

As energy prices continue to rise, the call for good insulation is getting louder and louder. There are two different ways of doing this in this area. One of them is to use styrofoam as thermal insulation from the inside.

Rising prices for heating costs are causing many to finally do something to reduce them. The alternative can only be to insulate. The best insulationthat can be done is that from the outside. Unfortunately, this is not possible, for example if it is a half-timbered building that is then also a listed building. However, many homeowners have also failed to do so building of your house to ensure that it is also protected against heat loss, and you have to retrofit it later. Then there is, for example, the effective solution to work with styrofoam as thermal insulation from the inside.

Using styrofoam as thermal insulation from the inside - the prerequisites

  • The most important requirement if you want to work with styrofoam as thermal insulation from the inside is that the material to be processed walls should be absolutely dry.
  • Freshly produced panels have the property that they will shrink a little over time, so you should always use something that has already been seasoned.
  • Make sure that the insulation is not installed too thickly, otherwise there is a risk that moisture in the masonry cannot evaporate from outside. Only if the outer walls are already protected against moisture, for example by a protruding one roof, the insulation can be applied thicker. This is already optimal with a panel thickness of 4-5 centimeters.

Processing styrofoam correctly - the procedure

  1. First you should provide the surfaces with a primer to reduce the absorbency. Then adhesive plaster is applied with a notched trowel and the panels are placed on top. Make sure that these are absolutely close together. You can easily saw the styrofoam sheets to size with a hand saw.

  2. Glue so-called flank insulation wedges to the corners of the room walls and ceilings that meet the outer walls to ensure that the insulation is absolutely watertight.
  3. Then glue them onto the panels and the adjacent window frame in the window reveals Windproof joint insulation tape to prevent moist air from getting under the insulation.
  4. When the insulation is complete, the reinforcement fabric is also attached to the panels with adhesive plaster. Adhesive plaster is then applied to this later, thus completing the thermal insulation from the inside.
