Construction materials

To build your house, the industrialists developed new products which improve comfort appreciably but of traditional materials remain very powerful.

 

In margin of traditional materials (blocks concrete, solid bricks in the Nord-Pas-de-Calais, hollow in the Large one Is…), the industrialists of the ship propose new product families able to improve interior comfort of the houses. Among most known, gas concrete, the brick and construction with framework wood.

Remarkable heat insulators and acoustics, these new construction materials are in addition to fantastic regulators of the hygroscopy of the ambient air.

Gas concrete

Older than it is thought (his creation goes back to 1927), the gas concrete also called is usually used. It is estimated, on a European scale, that 903 890 detached houses are built each year in .

Manufactured exclusively starting from natural raw materials, it results from a water dosage, of sand, #CACFA0 and of air. That confers at the same time the characteristics of a stone (solid, hard, indeformable, non-degradable and non flammable) and those of a isolating material to him (thanks to the air imprisoned in the cells), from where many advantages.

  • The gas concrete does not require any complementary interior isolating material. What allows an important space saver (about 4 to 5%) thanks to the absence of doubling.
  • is a material which breathes while letting migrate the water vapor naturally released by the occupants and their everyday activities. This is essential to avoid all risks of barrier to ambient moisture, the formation of condensation and the appearance of moulds.
  • It is a fireproof mineral material. Classified , is non flammable. It does not emit any gas, nor smoked toxic. In the event of fire, a wall in has a capacity firebreak six hour old. What will slow down the propagation of the disaster and will make it possible to limit the damage.

Solids, carriers, light, the blocks of make it possible to build the house of the sucker to the roof. The bonding of blocks is carried out using an mortar-adhesive.

Wood

Wood offers an alternative to “conventional” construction. Today, of this material progresses.

The house wood lends itself to various methods of construction:

  • solid mass (generally of the polar pine): logs and of beams which one piles up the ones on the others.
  • with framework wood: technique the most used today in the world. In the only United States, it builds each year more than one million with framework wood. Better still, in Canada and in Sweden, this type of construction represents more than 90% of the production of new detached houses.

How does the realization occur? The house is prefabricated in workshop. It is then transported and installed on the working. The time of intervention and the setting out of water and of air is very fast. It is a working without moisture, carried out with healthy materials which guarantee a natural habitat.

Another asset: will know that wood has a natural capacity of thermal insulation 350 times larger than steel and 10 times larger than the concrete. The complete absence of cold bridges and radiation of cold walls make an advantageous isolating material of it. Significant savings of heating can thus be realized.

Contrary to the generally accepted ideas, wood is a material who has one of the best fire resistances. It does not increase the fire hazards. On the contrary, it burns slowly without transmitting its heat to the close parties and without releasing from toxic smoke.

Lastly, the house of structure wood ages well. She escapes the conventional disasters like the fissures, condensation, packings and other penetrations of moisture.

The brick

The brick of is a construction material used since mists of time. Today still, it is very widespread on the workings, in particular in the areas deprived of rock.

Great innovation: under the generic name of , develops a large-sized alveolate brick which has a fantastic insulating capacity. is a constructive system which makes it possible to carry out a load-bearing wall without complementary insulation. Genuine thermal regulator, it stores heat in the course of the day and restores it the night. At the beautiful days, it acts like a natural air-conditioner: the house remains fresh when it is hot outside. Comfortable the summer, economic the winter, it makes it possible to carry out a saving in 10% on your invoice of heating.

It is also fireproof in the event of fire, easy to implement (what makes it possible to save time on the working) and ecological since it protects interior air quality of the house.

The block concrete or breeze block

It does not have good reputation inevitably… and yet the block concrete still called breeze block, , hardcore, is often wrongfully associated with the greyness of constructions of the Seventies. One believes it disrespectful of the environment: error! It offers opposite qualities exactly.

100% naturalness, 100% which can be recycled, the block concrete displays excellent performances in terms of comfort acoustic, thermal, of fire resistance, to the freezing and the effractions. All those which think it pollutant, he recalls that its life cycle is irreproachable. Composed exclusively of natural matters (94% of gravel, sand, clay and 6% of water), it requires little transport thanks to a mesh of 400 production sites in France and thus generates little carbon dioxide issuing.

Stone

The stone is not any more one material very much used. Considered expensive and difficult to implement, it disappears gradually from the new building to the profit of the Block concrete or brick.

However, Pierre de manufactured starting from a mixture of rocks of controlled origin and water pressurized according to a natural method of , forwards a mineral combination similar to the stone. During construction, it is left connect external side. Inside, it is associated with a work of thermo isolation.

Advantages: it offers same esthetic and patrimonial qualities that the stone of size but at competitive cost.

Other assets: implementation a fast with the mortar-adhesive to construct in only one stage the heavy castings and fronting out of stone, and a constructive system adapted to all the systems of thermal insulation: thin , isolating materials, polystyrene…

Lastly, it is a product which falls under step : waste recycling, energy saving.
