FAQS

Does the wood resists efforts as a building material?

Wood is a material that naturally arises now as constructive in nature if we look at the trees they have to put up with its structure (trunk) the efforts of the branches, snow, etc. It's as if you refer to compression as a pillar in a House. If in addition, added to this is you that you must withstand high winds and tree responds by flexing it laterally will understand that it is the same thing that happens on the beams of a building. Wood is an excellent construction material as media has a Flex of 24 N/mm2 and a modulus of elasticity around 10.000 N/mm2.

Can wood be used pre-cast nailed on the floor?

Wood certainly used to be in contact with the ground depending on wood species should receive a protective treatment. It is most common in Spain is using softwood such as pine, in this case use a protective treatment with water-soluble salts that give a greenish color which gives extra durability against degrading organisms.

Why cracking the wood?

It is very normal to check that the wood which is abroad presents a cracking, This is called fendado of wood. It is a process that undergoes the wood as a hygroscopic material (that Exchange moisture continuously with the environment that surrounds it). When the fendado on the wood it is because the wood has been supplied or placed with a humidity value of hygroscopic equilibrium very different will have in the conditions in which it is to be installed. However, It is logical and normal that the wood might appear some splits already that climatic variations (relative humidity and temperature) in Spain they are spacious.

The wood is degraded by insects

Effectively wood consists mainly of sugars that are likely to be degraded by organisms to feed. But not all species of wood are degradable by all insects and fungi and also depends on the degree of moisture in the wood, Since not all these pathologies target always. Why wood according to its final location should receive a protective treatment as other materials.

Guarantee of durability does treated lumber?

Treated wood has proven far superior to the natural durability. Depending on the final use should receive treatment in depth and number of guard so it can keep its visual and physical appearance without being altered by xylophagous agents of any kind. It is advisable to, maintenance of the surface layer on a regular basis. To learn the proper treatment it should be used to experts who advise or ANEPROMA so that it indicates depending on location and species to use what treatment to use, Since the wood well treated in accordance with the experience and rules can be very durable. Usually, considered that the useful life of the treated wood exceeds the 15-20 years in the case of the class 4, and the 50 in the case of the class 3. In this way, multiply by minimally 5 the useful life of the material.

The wood is burned and is a problem in the housing

Burning wood, But unlike any other material wood is the only material which referred to its combustion process. Time that will last the structure holding without problems of collapse can be calculated. However, other materials such as steel to a fire the material expands and collapses a mechanism of sudden ruin and thereby causing the fall of the building. It is common, think that wood is worse material against fire than any other. In fact, the carbonaceous layer that generates slows down the combustion process and serves as own insulation, Since it avoids the entry of oxygen. In the rest of materials should be used to isolate elements so that there is no direct contact with the fire. Again must be used to highly-trained technicians and experienced as ANEPROMA so that they can help indicate actions or treatments that improve the conditions of the wood fire.

What kinds of use?

It is a European standard that includes possible locations for an item of wood based on the content of moisture that may have. So there are 5 possible classes from inside class of use 1 abroad in water contact marina, kind of use 5. The standard is the UNE in 335.

There is a policy to collect the use of wood for construction

Yes, in the RD 314/2006 The technical building code, pick up the document's security structure wood (DB SEM), the use of wood as a building material, as well as the necessary considerations for its calculation and prescription.

To have a treatment with guarantees what should be required

First thing we need to determine which location will be the element (s) wood and then report to a specialized company carry a preventive treatment. The parameters to be controlled are penetration, It is the depth in mm guard entry and retention which means the amount of product that has been retained, usually in g/m2 kg/m3 for treatments in depth and surface treatments.

Creosote is prohibited

The use of creosote in Spain and Europe is not prohibited is restricted to a set of applications, such as the treatment of railway sleepers, wood farm, port areas and electrical conduits and telecommunication poles. Creosote is registered in the Ministry of health, area of biocides.

The wood protectors are bad for the environment

The first thing that should be checked when it acquires a guard is to check it has number of registration in the Ministry of health, as protector TP8. Then, as mark RD 830/2010 It can only be used by a qualified. They are registered products and that its proper use don't pollute the environment.

Are incompatible timber production and forest conservation?

Some decades, the mount is not logging, is harvested. The fact of consuming wood does not involve deforestation or biodiversity-ending, Despite the negative press that has been around this fact. Today, the speech has changed. The reality is that it is that it has been proven that existing forests today are due to a use that has led to the continuous regeneration of forests, encouraging that there are different generations of trees, great old, adults and young people. Non-intervention in forests is totally counterproductive since it leads to a mass of aged and incapable of reproduction and this is the end of biodiversity. In fact, any Government of the world, nor any nonprofit organization indicates that it does not consume wood but otherwise that is consumed but making responsible exploitation as today is the natural.

In Europe, as in Spain, There is a surplus of wood, and it is considered that it is consumed 1,5 m3 of wood, for 4 produced.

Are incompatible livestock production and forest conservation?

No, Not at all. In fact, cattle ranching, This is done in the forest environment, It allows the use of the natural resources of the territory, provided that it is carried out in an orderly manner. Ensure a proper stocking and apply active grazing techniques allows the conservation of natural pastures, belonging to the forestry, grasses that are crucial as sustenance of livestock (and as a result, be the source of income for much of the rural population) and configure communities of rich botanical species, varied, dynamic and landscape value, production and biodiversity.

Are prohibited wood for constructions of agricultural guidance?

No, in any case. In this respect there is no legislation indicating what should be the building material used for the making of stables, fences, Steering sleeves, etc. Indicated that the material must be washable and disinfectable, above aspects covered by wood. For this reason, It is recommended the use of this material by economy, ease of use, tradition, renewability of the same, etc. for any work of rehabilitation and/or restoration of livestock buildings or new creation works.
