Interior wall insulation - established insulation with simple installation

The thermal insulation of residential and working buildings is one of the essential measures to sustainably reduce energy consumption and to achieve a more pleasant living environment. In the selection of various insulation methods, the insulation of the interior walls is one of the simplest and most effective variants that can be retrofitted in old buildings or newer residential buildings. The application of insulation boards or a closed composite system inside the living space saves labor and costs that would be incurred in an external insulation. The latter is not even possible depending on the type of building, for example if it is a listed building and a modification of the facade and its appearance is prohibited.

In which cases the interior wall insulation is worthwhile

While exterior wall insulation absorbs cold and moisture even in front of the facade, the inner wall insulation only works inside the building. In addition to the insulating heat effect, an intact state of the masonry is therefore required. Although it is possible to benefit from the internal insulation of the walls in each type of house, no master of the house but wants to accept penetrating moisture and mold in masonry just like that. This can completely penetrate the façade during prolonged exposure and limit the effectiveness of the interior insulation.

The installation of a comprehensive interior wall insulation is relatively simple and often part of a comprehensive interior renovation. Especially with new buildings, it is very simple to mount an insulating layer before attaching more house installations or paint. If it comes to retrofitting with modern insulation materials, the dismantling of radiators, door frames & Co. must be considered. Compared to an insulation of external facades or roofs, however, the effort is limited.

Which insulating materials are used indoors

For the most part, homeowners opt for polystyrene panels, which offer innumerable advantages as a modern insulation material for the interior and, unfortunately, have yet to defend against individual prejudices. Industrially manufactured polystyrene panels meet the highest quality standards and are therefore neither easily flammable nor exposed to a higher risk of adulteration of the facades. They are affixed using special adhesives that ensure optimum durability even in the event of major temperature fluctuations, and even laypersons can easily attach them.

The use of insulating wool and other natural materials is possible, but in the implementation is more expensive and cumbersome. Various of these insulating materials require the construction of a stand construction, which create a cavity of a few centimeters deep on the inner walls and make it fill with insulation material of appropriate thickness. The construction makes it possible to choose more flexible the thickness of the insulating wall, but minimized by their attachment of the living space.

How much does the insulation in indoor rooms cost?

The inner wall insulation is one of the cheapest forms of modern thermal insulation, depending on the choice of insulation material should be expected at 40 to 50 euros per square meter without assembly costs. Exterior polystyrene insulation costs more than double, but may be more conducive to personal preference for protecting the dwelling and saving long term heat costs. Here it is important to decide on the right type of insulation in each case and to take equal account of budget and protection needs.
