Say, bham, you would not be style to see the straw in the message of your neighbor without seeing the beam ...

wouarfarfarf! 8)

otherwise, I was thinking the other day about a method of flocculating straw: crushed in a vegetable mill : Idea:

Hello,

And if we were talking about the acoustic qualities of cellular concrete ......
The material being very sparse, its qualities of sound insulation are disastrous.
I was able to "live" for a while in a villa entirely built in "siporex" and I do not recommend it to anyone.

I am in Pornichet

the lime / hemp coating is not cold, it takes almost room temperature.
excellent interior and exterior sound insulation. in addition to thermal.
no sound reverberation

concerning the coef lambda and others, it is a vast debate.
When we rebuilt with noble materials, I brought in an EDF agent to calculate my consumption for the promo label ...
loose hemp insulation under roof plus the rest in lime / hemp.
he was hallucinating. As usual 10 years ago we were on.
hemp in a house, kesako?
"do not know can not say, what is the coefficient K, the lambda, the conductivity ... etc". no conventionally measurable energy balance .....

nothing on inertia which is the priority in my opinion.
certainly a wall of pisa or bauge is less good cstb (etement) speaking
but in practice this is not the case because of this inertia.
and hygrometric regulation.

it would be interesting as obelix to have feedback on the siporex.
you say it sucks phonically. can you give us examples. where did the noise come from? the openings were they efficient phonic question because it is necessary to know if the noise passed through the ur or elsewhere?
was there a coating, a coating?

for the straw, it's a good plan but you need a wooden frame to hold everything it seems to me. So in terms of self-construction, we have to go through a craftsman beforehand. This seems to me to be a very good alternative which comes up against a delicate point, the shob and the shon.
who is ready to declare walls 60 cm thick and therefore lose living space and pay taxes for an unusable space knowing that the average thickness of the walls is about 35cm for 105m2.

for the figures it's not my thing, but to say that 40cm of pizza is equivalent to 2m of concrete: no sorry, yes the coef and blah blah, in practice it is quite different, and know that a wall in pizza doesn ' is not easy to destroy (with backhoe loader) it is flexible and durable over time, stronger than concrete !!! we will see in 400 years the concrete mouth! eternal earth if sheltered from water, and on site, no transport, no chemical reaction, I see concrete made 15 years ago falling apart !! (yet dose well)

despite these evidences we continue with concrete because it is inexpensive easy to implement and very quickly exploitable.
but the resistance over time leaves something to be desired; but in this consumer society, this is part of the game.
we can no longer wait for the coatings to dry, we no longer support the slightest crack, craftsmen must use shit products, ecologically disastrous, but which do not show any defect for 10 years. it's the game again. it is the buyers the wrongdoers in a certain sense.

Hello everyone.

this summer I participated in a straw construction course in the charente. It is a very warm house. it neither has humidity. In winter it is heated with a mass stove (It uses 5 stakes of winegrower to heat a whole day.)

it will even be possible to use straw and earth to insulate a stone wall.

Jonule can you share with us, your idea for creating a home-made stove.
