How much does 1 m2 of full thermal insulation cost?
How much does 100 square meters of facade insulation cost?
How much does full thermal insulation cost for a detached house?
The average cost of full thermal insulation (façade insulation) is between EUR 90 and EUR 400 per m², but can also be above or below this range in individual cases.
How much does 1 square meter of external insulation cost?
In general, you have to reckon with 20 to 400 euros per square meter for facade insulation. On average, one square meter of subsequently insulated facade costs around 123 euros. With a facade area of 150 square meters, that makes 18.450 euros.
How much does facade insulation and plastering cost?
With the thermal composite system, the craftsmen charge 30 euros per square meter for insulation and 40 euros for plastering. In the case of the curtain wall, the assembly of laths and insulation costs 35 euros, the new facade 70 euros.

Does full thermal protection make sense?
The full thermal protection makes sense and can also be carried out in the course of another renovation activity. After all, this prevents heat from being increasingly emitted from the inside via the outer walls of a building. Energy is a valuable commodity.
Should you insulate an old house?
Does my old house need to be insulated? This question sooner or later arises for every owner of an old house. There is only one correct answer to this: No, you don’t have to! There is no law in the Federal Republic that requires homeowners to insulate an old property.
Which external insulation for old buildings?
Core insulation is by far the cheapest variant of external wall insulation. Most of the houses built in northern Germany between 1900 and 1973 have double-shell masonry with a 4-7 cm hollow layer. The insulation value of such an outer wall corresponds to about 2 cm of cellulose insulation — you are almost sitting outside.
How thick does the façade insulation have to be?
Thermal insulation of the façade must be 12 to 16 centimeters thick — this is what the Energy Saving Ordinance (EnEV), which has been in force since 2014, stipulates.
How much does Styrofoam facade cost?
Styrofoam panels are glued and plastered to the facade. The costs depend on the required insulation thickness and the type of facade. In most cases, they are between EUR 100 per m² and EUR 140 per m².
Does façade insulation make sense in old buildings?
A well-insulated house shell forms the best basis for this: Once installed, it reliably ensures low heating costs for decades. The flawlessly installed facade insulation of the old building achieves a minimal heat exchange between inside and outside. That way, the heat stays inside.
How many square meters of facade does a detached house have?
*A facade surface is 100 m² on average and may deviate from your area size. **Prices are indicative and serve as a guide. With professional facade cleaning, you can remove algae and fungi from the facade.
What is the best external insulation?
With a lambda value between 0,033 and 0,040, stone wool offers an average insulation value. This makes rockwool an excellent material for thermal insulation (warmth). Rock wool or rock wool panels are also recommended for sound insulation.
Why has insulation become so expensive?
The reason for the price increases: The PUR precursor methylene diphenyl isocyanate (MDI) for the production of PU insulating boards is currently in short supply. According to the Rigid Polyurethane Foam Industry Association, it is manufactured in a small number of plants in Europe, North America and Asia.
When is façade insulation worthwhile?
For example, insulation on exterior walls built before 1977 pays for itself after 4 to 10 years, most likely after 6 years. Insulating the facades of newer houses pays for itself after 9 to 22 years, typically around 14 years.
What’s the point of 10 cm of insulation?
10 cm of insulating material results in a U-value of 0,4 W/m²K. 20 cm of insulating material results in a U-value of 0,2 W/m²K. 40 cm of insulating material results in a U-value of 0,1 W/m²K.
Which insulation thickness makes sense?
“Whenever more than 10 percent of a component area is repaired, the Energy Saving Ordinance (EnEV) applies. Today it requires a U-value of 0,24 W/(m2K). That’s around 12 centimeters of insulating material. The legislator thus prescribes a very sensible insulation thickness.
Can you insulate too much?
Too much insulation leads to mold growth
Mold indoors usually occurs where humidity condenses on cold surfaces, i.e. moisture is deposited.
What insulation thickness old building?
In old buildings, there is only an obligation to insulate the top floor ceiling if this does not meet the minimum thermal insulation requirements according to DIN 4108-2: 2013-02 (corresponds to around 5 cm insulation material thickness).
Do you still insulate with styrofoam?
The insulating material is listed in building material class B1, i.e. it is considered to be flame retardant. So far, the toxic fire retardant HBCD has been used, which has since been banned. The transitional period will end in August 2015, after which it will no longer be possible to sell insulating boards with HBCD.
How long does a styrofoam facade last?
The researchers therefore assume that ETICS will have a service life of 40 to 60 years; doubling up in the meantime could extend this period by further decades. The vast majority of ETICS achieve long life cycles without a great deal of maintenance.
Why not insulate old buildings?
A poorly insulated building shell, old windows or an uninsulated roof drive up heating costs. Up to 40% of the heating energy is lost through a poorly insulated pitched roof alone. With a well-insulated home, you can significantly reduce your heating costs.
Where is most of the heat lost in the house?
But now we come to the results: The façade is responsible for the greatest heat loss in the energieheld house. Here, a good 30 percent of the total heat loss is released into the environment. The outer wall is closely followed by the roof. Through this, 20 percent of the heat escapes from the house.
What good is 2 cm of insulation?
Especially for rooms that are only used and heated sporadically, interior insulation with UdiIN 2CM® offers decisive energetic advantages. The rooms, which are insulated from the inside, can be heated up very quickly because the massive outer walls do not have to be heated at the same time.
