... sorry, but someone to whom "it is necessary" to repeat over and over again that it is first necessary to clearly identify the causes before dealing with effects, has not yet learned or understood anything! And I don't want to extend the enormities, because there are many ... Like that of persisting in mistakes ...
... all the more reason to be humble in this area: it is scary when you read from the second post - when we still only have disparate elements, therefore totally insufficient - that someone supports such affirmations ....:dedeleco wrote:even BAC + XXL are still having and being ripped off sometimes, like me, because we cannot know everything and the evaluation of the optimum is not always easy !!
... while the photos show that there is already a very basic insulation: we see wood, already not so bad ... then closed boxes in apparently uninhabited attic ... I know many houses of which insulate the walls, which don't even (need) that! It would be necessary to see on the spot ... but by correcting a few points, it is possibly possible that there is not much to do in this attic!moby25 wrote:You have to indeed start with the roof [...]
... so affirm what he says - twice repetita - without having taken care to warn about the dew point !!! Without any evaluation of the rest! Either without being informed about which heating system could replace the existing one, without knowing if there is or not a ventilation, if one is in the presence or not of construction with double windows, and especially if there is, or not , any air inlets? Last but not least, without having taken the trouble to assess who we are dealing with, to predict to what extent the wise advice will be understood and above all followed by effect ... All this is absurd ... Otherwise remedies and initiatives can -be worse than evil. However Moby should know something about it, since he has been there! But it's peanut!
... you will excuse me, for once, for not sharing your opinion! The air intakes and cold bridges are the first things to look at after making an overall inventory on site!
===================================
In addition ... as an example, when we allow ourselves to say, dare-dare:

... while one has oneself suffers a catastrophic condensation problem, notably due to cold bridge / s and while these are not yet imperatively identified, that doesn't give a damn! This is why a “heat balance” must be made. It does not cost much and we see immediately where to intervene first: better than a long speech !!! "Identification of the causes", then fixing of the priorities namely "where and how to intervene" ... and not say ex abrupto "it is necessary" start there ... then realize that it was not the right thing to do ... and have a heat balance afterwards ...
Even with experience ... it is difficult to do without it today, it is so sharp because we always discover amazing things! And people - and rightly so - are more and more demanding as to the expected gains ... If today we have such a tool that is the infrared signature ... you really should not hesitate!
... not a word on cellulose wadding? Cork ... and many other insulators, which must ALL be chosen according to needs and circumstances ... It's really the ponpon!moby25 wrote:To insulate "ecological", there are indeed rigid wood wool panels (or semi-rigid) but that may be expensive.

zero for college!After ... we can always back up his speech with diagrams stuck on the woueb (without indicating the source ...) to play it "pro" ... it does not prevent such an approach clearly showing heavy deficiencies which means that his reasoning is totally off the mark and devoid of common sense, if not professionalism! It would be laughable, if errors in the building were not as expensive! Especially when he is in the situation of having to rebuild the floors of his pavilion ... ^^
===================================
that's not what the photos say! Furthermore, after breaking the wall "to see" (if, if ... ^^), he himself said that the chipboard was completely soaked on the edge at the precise place of the anchoring in the Wall!!!dedeleco wrote:In addition, its "floor support structure and joists" are only very partially "dirtily soaked in water",
Hence the fear that the structure will partially collapse (?) By loss of lift resulting from the sliding / detachment of the first concrete block leading the others to collapse! It is not trivial! All the more so because at this precise location, there is already a predictable fracture zone !!!
since he did not follow what was said, it proves that he has not learned, that he is not meticulous (you repeated it) and besides y'a- is there a leak in bathroom or not? ... We never knew exactly! No following! Denial! No feedback from the architect ...! Blah-blah! Diagrams stuck here or there, chosen at "p'tit bonheur la chance" and applied out of any context .... finally Dedelco, you have to open your eyes a little! It's called a bracaillon and the least you can do is warn others!dedeleco wrote:a very small proportion which is probably due to condensation in the bathroom which seeps into the chipboard, on the photo.
