PLop I read that in Belgium the rules are as known as in France
and its dependent on the taste of the people present around the table and not necessarily taking into account the logic of construction, arfff bay window to the north lol. We are not spoiled, but little by little the ideas evolves, we must not get left do and talk to the right people who will give them the right detours to ultimately have what we want
.
Impressive sanding result, and good idea for waterproofing (micro porous or not;) it will be determined if you use a steam brake or not, if waterproof then vapor barrier be careful).
for the chanvriblock look at the lambda coefficient (the y has the reverse); it is 0.07 W / m² K, I will give you the definition of an insulating product now: any product with a lambda equal to or less than 0.04 w / M² K conclusion: hemp is like hemp and lime not strictly speaking an insulator , but a "thermal corrector" which will also act as a vapor brake (so well implemented), it will allow to have a variable humidity rate depending on the season (less humid in winter and more humid in summer) contributing to a well-being of life. Personally I like hemp and lime plaster directly (on old 55 cm thick stone walls), and on brick walls I can't give too much advice for plaster, I am not at the point at all the above here the brick have not know except the alveolar (but with the lambda you will draw the conclusions which are essential of themselves
concerning chanvribloc).
As for the dry screed it is a compromise which should be acceptable quite acceptable even without causing too much work.
I will suddenly answer the question of obamot write in very small that stings my eyes
so it's written small;).
How you know obamot my little Swiss;)
all the houses are not alike and each old building has a construction method typical of the place where it was made
.
here with us the soil is generally beneficial so our foundations do not go down very low, like at 60 cm I no longer have a foundation on my house
(er actually if I have giant blocks of granite
) little anecdote I already broke three pickaxe by making a trench to put a drain and it is not the handle that I broke but beautiful and well the tip of the pickaxe at the level of the ring which surrounds the handle, Now I call my neighbor with his flyer which wears out its serious teeth
.
Regarding the delta Ms, I agree for concrete block but not for stone walls if unfortunately the dry wall too much the mortar will dry too and suddenly you help your wall to break, to reverse me I prefer to dig into it
, I pour the chappe and the slab, which I replace with a slab (which can also act as a chappe depending on the materials used for the soil then) with pozzolana or perlite as gravel, so it becomes semi-insulating, the best for me is to make a lime concrete lime cement slab (like NHL5 Z) with perlite or pozzolan;), but this is valid for us because granite underneath so the slab is not a slab carrier;), it just carries us and the furniture and partitions etc.
By cons on the periphery of the slab a layer of insulation, and suddenly I have a good insulating junction between floor and wall, and a semi-detached insulated slab but which heats up like the plaster when we touch them, it reflects our own well heat (this method is valid on solid ground because in a case of crawl space it is yet another story and it is even simpler;) we make a wooden frame house floor insulated as desired
).
And in the case of external insulation on an old house, well ??? it all depends on the condition of the wall and its construction, if it is full of small stone it is without regret that we can make an external insulation. on the other hand there are crazy walls, yes yes, crazy guys who did that, on the house of a friend (house of 1780 I think) there are arches in solid granite cut and placed in floor yes yes the blocks are at least 500Kg each and one wonders how the craftsmen mounted it, then in this case hiding it is out of the question it is too good and for the respect of the work we must keep them visible.
So here is my opinion as you know depending on the house the opinion changes
, each case is a separate case.
but your technique is good too obamot and I would do maybe the same thing as you with the houses around you
.
does that suit you as an answer my dear Swiss builder
and you saw the hygrothermal balance well eh;), but I'm for nothing I just found the link
