Construction in straw, like all other constructions containing vegetable materials besides, existed since thousands of years in all the corners of the world. But it was officialized in the USA only towards the end of the 19th century and in the years 1920 in France. She knows more and more followers in this moment, because besides being ecological, she has other practical advantages to the daily newspaper.
Ecological properties of the straw
The reduction of the gas emission in the atmosphere is one of the broad world objectives of small, average or large companies but also of the private individuals. To reach this finality, the straw is used more and more to build houses because it is the ideal material for that.
It is at the same time natural, renewable and which can be recycled but is also famous for its thermal exploits and its insulator characteristics. Like wood, another ecological material, the straw preserves CO2 and thus emits less gas. Moreover, it is not necessary to use gray energy by producing it and besides its lightness, it is not useful to invest enormously in its transport.
The straw is sold in bundles, often in farmers and is a really accessible material because of its low price. In general, one or two euros is enough to acquire a bundle. And for a construction in straw, it is not useful any more to make use of a reinforced concrete and other industrial materials. Wood for the framework as well as stones and limes will get the bargain.
For any individual who wishes ecological houses at low prices, best is to build them with straw. Moreover, the car construction can be held well with this material what allows a tiny cost of work because that borders the 500 to 1000 euros/m ². Even while engaging of the people receiving benefits on the matter, the price remains still accessible: 1500 euros/m2.
Many individuals hesitate to build a house of this type because they hesitate over the solidity of this material. But of many residences must however convince them with the example of the house of Divides into sheets, built in 1921 and which always inhabited until now.
Ecological construction: positive impact of the straw
Other criteria still make it possible to say that a dwelling in straw is advantageous because when the materials are assembled, they resist fire well. The example of a dictionary and a sheet of paper can explain this phenomenon. The sheet of paper perishes directly after being exposed with fire. The dictionary, has difficulty to him being carbonized, a fact which can be transposed to the bale of straw.
In addition, the materials necessary can be easily because they are available a little everywhere as in the farmers. There are wood, the lime and the ground except for glasses and of plumbings. In addition, construction is done more quickly compared to the ordinary one, in only into one to two tens of days. And the future owner can even proceed to the car construction while being made help by local inhabitants. |
