Now there are some interesting programs about the insulation craze with ETICS.
It would be wrong, flammable, moisture between ETICS and masonry, etc. etc.
These programs have a certain entertainment value, but I wouldn’t exactly describe them as reliable sources of information ^^
Especially the arguments from KoFi, who apparently gets to chime in on every program, I always find quite amusing... Solar gains... don’t make me laugh...
What problems do you again expect from a ETICS made of EPS?
Flammable?
Under certain conditions, almost everything is flammable... Does a properly installed ETICS burn spectacularly during a room fire, as reported in the 45-minute program by NDR? There is now a statement on the Internet about this exact program saying that the test setup did not correspond to real conditions, especially due to the chimney effect... Recently, there was another such fire test on Welt der Wunder... a room fire was simulated by the fire brigade on a wall insulated with EPS... everything burned except the EPS... can be found on rtl2’s website...
I also don't know of many fires in single-family homes that have been traced back to ETICS...
Moisture?
Of course, you should make sure during installation that everything is sealed properly and that water cannot continuously run behind the ETICS... But I wouldn’t see such gross installation errors as a general disadvantage of ETICS... Or would you refrain from buying a car because the gasoline engine doesn’t work anymore if you put diesel in it?
Hazardous waste?
What does hazardous waste mean? That it has to be disposed of separately and not just thrown in the regular trash? Most construction debris has to be delivered separately anyway... For 100 kg of EPS, I pay about €21 at my local disposal facility... you can get rid of a whole house facade for less than €100...
One could go on forever like this... The fact is that most of the arguments are not sound but mostly scare tactics or simply hardly relevant! EPS is, for example, not particularly diffusion-open! Is that bad now? Actually no, because the amount of moisture that diffuses through the walls is minimal and almost negligible anyway! Whether that’s 1% or 2% doesn’t matter... you have to ventilate to get rid of the moisture! But it sounds good when you say that the whole thing is not diffusion-open... at first it sounds like a musty climate inside ^^
And it’s not as if a monolithic wall construction, whether Poroton or aerated concrete, is without disadvantages... I think of cracking, summer heat protection, thick walls, special anchors in the interior, etc... often with a nice extra charge!
If I were you, I wouldn’t let myself panic but would critically question every single point that bothers you about ETICS!
Of course, you can also build without ETICS! You just shouldn't believe that you have built the "better" or even "healthier" house that way... other factors often play a much bigger role!
