house built in blocks

[myface]

Hello everyone, I need a advice from those who have experiences as a builder or restorer: I would have found an old single house (60s) in good position only that the perimeter walls are made of concrete blocks (those made with gravel and concrete, emptied inside, to understand).

Everyone tells me that I should knock it down and rebuild it, because thermally that material is worth zero, but I was wondering if there was a valid alternative in this regard, to save naturally :smile:.

In particular, I was thinking of considering the current construction only as a "support" and of building (in addition to the plants) a new wall inside to obtain acceptable insulation and habitability.

Is that a viable solution? What kind of problems could arise?

It's a structure made with the mythical "blocks", I lived as a child near a factory that made them, I remember an outdoor pavement of fresh blocks just "defecati" from the automatic machine, they were soft as a cake and we enjoyed destroying someone, causing terrible pursuits by the master.. .
I'm sorry, I just...
I would say that if from the structural point of view the walls are in place, which you can tell by a trusted technician, probably the best solution is to make him a "cap" with adequate materials and thicknesses to calculate; Basically, imagine you're the bone in blocks and feel cold, what are you doing? put on a nice coat, that is, add an insulating layer from the outside.
If you ship a bit in the building sites you will find a lot of information about this "classic" system, or ask some technicians you trust, it is generally not a very honest operation.

thanks for the attention in the meantime. I know that now it is customary to make also on the new houses the "coup" , i.e. to cover them externally of insulation panels (of the most various materials, bio and not.)

But more people told me that in my case it would be money thrown, or down there. I do not understand the technical reasons for such an analysis, nor the people in question have motivated me.

for this reason I thought then to dress internally (health knit:tongue: instead of coat, to stay in the dress metaphor! )

 

[warburg]

not seeing the structure risk of saying chestnuts, but generally it is not logical to dress from the inside, because the isolation is not as effective; the coat instead exploits, to achieve a good degree of insulation, also the existing walls: cold and warm from the outside meet more insulating layers: first the new ones of the coat, then the ones albeit weak existing, while instead the opposite allocates all the insulating capacity to the only internal new layer, which consequently must be oversized etc.
so, grossly.
recommended, maybe even from the sale of building materials, a council does not commit you.

Thank you very much. but I hope to find someone who has faced problems like mine to understand in the practice where you end up...:smile:

construction in concrete blocks if well made of rather long drate. Therefore if the structure is well built, if it has not had damage, in principle you can keep it as it is. the checks can make you a technician enabled by making texts to the masonry and foundations. with a few billion euros you certify compliance with seismic regulations.
As far as isolation is concerned, it must be verified exactly as the wall is made. in principle, if the house at some ten years is normal it is not great that, but usually you can start. How old is this building?

the coat you can put on everything and I don't see any more problems than with any other twist if you have any money you can evaluate alternatives.

therefore the fundamental point is if the stunt is still in good condition

yes the house is of the 60s, therefore it is about 50 years old. The only one is to look for a good expert and make him assess the situation. Hi.

as much as the thermal insulation rejuvenates, it safely executes the outer coat, with the firmness of isolating everything under the roof.
Moreover it also isolates well the attic with material type "materassino" laid in the attic (above the ceiling), and the floor, always with adequate material, if instead it is above the cellar/box, and do not interfere on the ceiling apply panels on the intradox of the loft.
pay attention to the so-called "thermal bridges" (cross/angels) of perimeter structures, which require "specialistic" insulation
In general, the external "couple" is the best insulation solution of existing structures, compared to "internal" solutions.
for coat thicknesses, turn to a technician who will advise you at best. do not forget the windows and doors

hi myface, I just bought a house similar to yours, indeed just like a floor and in concrete blocks, can I ask you how you did the restoration of the house? various reinforcements and coat? Does it work?
thanks in advance
