{{Short description|A wooden house is warm, durable and has character. It's eco-friendly, green and has a low carbon footprint.}}
{{Unreferenced section|date=April 2024}}

There have long been many types of '''wooden houses''', the main building models of which are:
* house with pole/beam structure;
* The house made of solid [[plywood]] panels;
* the wooden frame house;
* the stacked solid wood house (planks, trunks or logs, wooden block).

== Ecological and sustainable ==
[[File:Oregon Caves Chateau OR1.jpg|thumb|Wood construction in [[Oregon]].]]
Wood can be durable over time. For example, there are several hundred-year-old [[Timber framing|half-timbered houses]] in different parts of [[Europe]] ([[Germany]], [[France]], [[Norway]], [[Switzerland]], etc.) or in [[Asia]].

In addition to being recyclable and biodegradable (if it has not been varnished or treated), wood is also a source of energy thanks to its combustion.

== Energy-saving material ==
The energy consumption required to transport and process the materials used in the construction of a wooden house is currently unknown. Indeed, there is no [[:fr:Fiche_de_déclaration_environnementale_et_sanitaire|environmental and health statement sheet]] for wooden houses that would clearly quantify the carbon impact of this material.

== Wood and CO2 emissions ==
[[File:paris-Volta.JPG|thumb|House built in 1644, [[:fr:Rue_Volta|street Volta]], [[Paris]].|217x217px]]
During the manufacture of materials used in the development of any home, energy is consumed but especially pollution is released into the atmosphere in the form of mainly [[Carbon dioxide|CO2]]. Depending on the materials processed, the amount of CO2 produced differs. Wood can reduce the amount of CO2 released into the atmosphere by half. In addition, wood has a significant CO2 storage capacity, which limits its release. However, the destruction of wood (natural or by combustion) results in the release into the atmosphere of all the CO2 previously stored.

Another environmental aspect of a wood construction site is the small amount of waste on the site because all the waste can be recycled or burned in a heater.

== House with pole/beam structure ==
[[File:WuzhenWaterway.jpg|thumb|[[Wuzhen]] village, [[China]].]]
The supporting structure of the house consists of [[Post (structural)|columns]] and [[Beam (structure)|beams]] usually made of solid wood or [[Glued laminated timber|glulam]], rigidly assembled between them which gives it a great formability. Between these load-bearing elements are inserted [[Bay window|bay windows]] that, when fixed, can be installed without the use of intermediate joinery, non-load-bearing insulating masonry blocks (for example, [[Hempcrete|hemp concrete blocks]]), wall elements that may consist of a wood frame (as in the wood frame house described below) or a stack of [[Plank (wood)|planks]] as in the case of the frame «at the meagevanne» ([[Megève]] region).These walls serve as fillers and have no bearing role. The construction can be done on site, but gains a lot of precision and reliability to be carried out in a workshop. This type of construction allows large spans preserving large free volumes and very open facades. Its complexity of realization usually reserves it for quality achievements or southern facades of bioclimatic constructions.

== House in solid wood panels ==
This mode of construction tends to develop in [[France]]. It is common in [[Austria]], [[Germany]], [[Belgium]] and [[Switzerland]]. The main manufacturers are: Schilliger, KLH, Finnforest, Binderholz, MHM, Biospeedhome, etc.

== Interesting mode ==
This wood construction technique is a combination of frame systems and solid timber: aesthetically, it has the same appearance interests as the wood frame house (cladding, coating, painted or rough on the outside on a reported insulation and with multiple possible finishes for the interior, including the natural wood appearance of the panels), with the performance of solid wood in terms of inertia. The solid panel material makes it possible to optimize the use of wood by giving it equivalent mechanical characteristics in all directions, eliminating the veil and deformations due to aging or hygrometry, and allowing unprecedented architectural freedom.

This system is expected to develop with the increase in the energy and thermal performance of buildings. It is also recognized that massive panel constructions are more earthquake resistant [ref. needed<ref>An editor has indicated that this claim needs a citation to a reliable source.

</ref>]. There are currently buildings of more than six floors composed of panels, some even reaching ten floors.

== Long-term stability ==
The current techniques allow the realization in the factories of walls of great length (up to 24 m) and variable thickness (from 7.8 to 50 cm) obtained by the assembly of wooden boards glued or nailed to each other in multiple crossed folds. This type of wood construction ensures remarkable stability over time.

== Multiple usage ==
These panels against glued can make a house from floor to [[ceiling]]. The house can be built on a conventional concrete slab, or on [[Piloti|stilts]], in which case the [[floor]] can also be laid in panel. All walls made with this type of panel are load-bearing. Floors and roofs can also be made as well.

== Surprising realizations ==
These panels are resistant to strong overhangs, which allows balconies without support by beams.

== Wooden frame house (MOB) ==
The [[Framing (construction)|wood frame house]] is the best construction technique for most regional styles, so it’s the most common. The walls of the wooden frame house are made on the basis of a structure consisting of wooden frames spaced 40 or 60 cm apart (in general) between which are placed the [[:fr:Isolant|insulating materials]]. This construction technique also allows the prefabrication of complete walls in the factory, sheltered from the [[:fr:Intempérie|weather]]. The completion of the canopy enclosure can be achieved in just a few days, since there is no drying time.

The tendency to better insulate houses leads more and more to double this framework with external peripheral insulation of heavy insulating material (type wood fiber for example) that improves insulation, provides better thermal dephasing for the benefit of summer comfort and eliminates all thermal bridges attributable to the wood frame. The wooden frame house allows more economical and quick to implement expansions.

== Exterior cladding ==
[[File:Maisons bois.jpg|thumb|Wooden holiday homes in the Jura.]]
It serves as a bulwark against bad weather. It is often made of cladding, that is, wooden boards that can be painted, treated or left natural. Wood (especially untreated) exposed to sunlight and the elements will take on a gray hue over time, but will not lose any of its mechanical qualities. The exterior siding can also be made with a coating.

== Great freedom of interior finishing ==
The inner walls are most often made with [[Drywall|plaster panels]] offering multiple possibilities of finishes ([[paint]], [[wallpaper]], etc.). Because of this, the wood frame house seduces followers of a moderate presence of wood.

== Wrong idea ==
It is often argued in favor of the wooden house that for a quality of insulation identical to that of a [[masonry]] construction, the wall of a wooden construction is 40% thinner, This represents additional significant square meters in case of urban planning constraints and resale. In practice, the interest of wood construction lies, among other things, in the possibility of making a house much better insulated and more comfortable than a masonry house. Therefore, it is logical to increase the insulation thickness significantly, as explained above, the additional cost being very limited as a percentage of the total construction price, and in any case minimal compared to the expected energy savings. In addition, since a wooden house is not designed on the model of a masonry house, there is a good chance that the [[architecture]] and surfaces will differ. The surface gain is therefore no longer significant and is, in any case, not a good selling point against the detractors of the house of the ''[[The Three Little Pigs|Three Little Pigs]]'' «in boards».

However, the [[Thermal conductance and resistance|thermal resistance]] of the materials used for the construction of wooden frame houses is different from the materials used for the construction of traditional houses. The thickness of the different materials for the same thermal resistance (0.50 m2 °C W 1) is as follows<ref>An editor has indicated that this claim needs a citation to a reliable source. (mars 2011)

</ref>

* solid concrete: 88 cm;
* Hollow block: 52 cm;
* Pisé: 39 cm;
* Solid brick: 28 cm;
* Softwood: 7.5 cm;
* hemp concrete: 6.5 cm;
* cork, cellulose panels, mineral wool: 2 cm.

The surface gain will depend on the type of construction as well as the type of material used.

== prefabrication ==
One of the advantages of wood frame construction is that it allows the workshop manufacture of wall panels, dry, safe. Once the walls are finished, they are loaded on a semi-trailer and then mounted on the site using a crane arm or crane.

Thus, in two days, the walls are standing; it remains only the floors or framework to mount before the house is out of water. This manufacturing method requires anticipation, good supply management, design mastered to the millimeter, synchronization with other trades, but it ensures that the wood has not been subjected for several weeks to bad weather (unlike mounting walls on the slab).

A more successful stage of prefabrication is to manufacture in advance, in the workshop, the floors and the frames. For example, a framework is in the form of boxes that are mounted on site by a crane.

== Stacked solid wood house and wooden masonry ==
[[File:pobikry dwór.jpg|thumb|221x221px|Traditional construction, Eastern Europe.]]
Often called a [[Chalet|cottage]], it consists of solid wood walls mounted in stacks of planks (rectangular finish), logs (smooth finish) or [[:fr:Fuste_(produit)|charcoal]] (rustic finish).

Wood masonry is the use of solid wood blocks. These are stacked using the masonry technique. This technique gives the opportunity to realize all architectures, promotes self-construction and the realization of solid wood house with a minimum of tools.

New techniques now make it possible to mount a wooden chalet by assembling pre-cut wooden planks in kit. The thickness of the planks is generally between 28 and 60 mm depending on the manufacturer and the range<ref>«[https://www.prokit.fr/les-etapes-de-montage-d-un-chalet-de-jardin-en-bois.html The stages of assembly of a wooden garden cottage, from the foundations to the roof]», on prokit.fr, November 23, 2021 (consulted on December 10, 2021).</ref>. The assembly takes place in stages following a manual and requires very little knowledge in carpentry or framing.

== Lack of inertia ==
Despite its thickness, solid wood has a so-called light inertia. This is why this wooden construction technique is very common in [[North America|North American]] countries or in the mountainous regions of [[Europe]].

On the other hand, wood is an average insulator (lambda coefficient of 0.12) compared to materials specifically intended for this use (0.04 on average for [[:fr:Laine_de_roche|rock wool]], wood fibre, [[cellulose]] or [[hemp]]). To obtain an insulation coefficient comparable to that of a wood frame wall, it is essential to add a thickness of insulation, ideally from the outside, so as to benefit from the inertia of solid wood inside the construction. The exterior insulation can then be lined with thick boards that will restore the «chalet» spirit. It is no longer necessary to provide insulation inside. This allows the occupants to fully enjoy the warm presence of wood, for a long time.

The modern design of the stacked solid timber construction allows very significant thermal gains by the design of the walls of the buildings: simple timber with insulation from the outside (avoids thermal bridges that cause significant thermal leakage) or double planks that trap the insulation (the thickness of which can vary depending on the location and needs).

The species most frequently used for this type of construction are [[larch]], [[spruce]], [[Thuja plicata|red cedar]], [[Pinus sylvestris|scots pine]] and [[douglas fir]].

New wooden houses usually offer very reliable insulation thanks to a double plank system with insulation in between. For example, instead of having a wood thickness of 120 mm, there are two 60 mm planks with a layer of 80 mm insulation inside<ref>“[https://www.chalet-conseil.com/isoler-un-chalet.html Insulating a solid wood cottage: the complete 2022 guide with RE2020 standard]”, on chalet-conseil.com, October 14, 2022 (accessed November 4, 2022).</ref>.

== Importance of the moment of cutting the tree and drying the wood ==
[[Woodworking]] must meet certain criteria to have a home offering the best possible quality. It is important to take into consideration when the tree needs to be [[Felling|felled]], and the method of [[Wood drying|drying]], to obtain strong and well-preserved wood.

The tree must be cut in [[winter]], or possibly in [[autumn]], when the tree is at rest and the [[sap]] circulates very slowly<ref>An editor has indicated that this claim needs a citation to a reliable source.

</ref> [ref.necessary]. It is then said to be “not sap”, and therefore less prone to [[fermentation]] and [[insect]] attacks.

Natural drying, which can take at least a year, offers even better resistance to timber<ref>An editor has indicated that this claim needs a citation to a reliable source.

</ref> [ref. needed]. It must be protected from the [[Rain|elements]], but stored in the open air, to have a good air circulation and thus avoid the accumulation of [[moisture]] and proliferation of [[Fungus|fungi]] and other [[Parasitism|parasites]], then be stored for a week in the dry, in a depot, before being worked.

Industrial wood does not always respect the right cutting season. It is also cut in [[Spring (season)|spring]] and [[summer]], and undergoes kiln drying, which gives construction wood, certainly cheaper to acquire, but also, of lower quality and will have to be treated more often<ref>Corinne Savoyen, [https://www.programme.tv/programme/ma-maison-en-bois-4402571/ My house in wood], on programme.tv, documentary, 2013.</ref>.
