Mallorquinas ANALYSIS OF MATERIALS: Windows The windows are one of the most important housing. From the point of view of windows used bio to provide natural light, warm sunny days in winter and cooling in the summer night. But too much area devoted to windows can result in high energy losses in winter and excessive profits in the summer. Therefore we must choose windows and high insulation value with a moderate size.
Our choice:
windows We have chosen Swedish pine certified FSC sustainable management and treated with organic coatings. Wood is a renewable material with high insulating capacity, making to be an ideal material for windows. The only negative point of wood is its weakness against the sun, therefore, in climates like the Mediterranean, it is preferable that the paints used are of dark tones. It is very important that the wood used is of European origin, since the harvested in other areas, especially Africa and Asia, is often extracted in "illegal" damaging to ecosystems and local communities. Never buy some windows or other products from iroko or teak. glasses are double (3 +3/16/4) with a 16mm tube. filled with argon and solar control. Argon is a noble gas of low thermal conductivity, thereby achieves excellent insulation.
The windows have been manufactured by Benito Systems, a company listed in the chain of custody, so you can ensure sustainable source of wood used. The distribution and installation has been done by Tecnimatic .
Other alternatives:
Unfortunately, the windows used in construction are PVC and aluminum, both with serious negative consequences for the environment. PVC windows produce a large amount of toxic pollutants related to chlorine, both during manufacture and end of life. They are also made from renewable materials are not recyclable. The only positive point of PVC is its high insulation value. Aluminum windows are a less toxic alternative to PVC, but bauxite mines of which are mined cause serious environmental and social problems in the areas of operation. The high thermal conductivity of aluminum is essential to use windows with thermal break. An acceptable alternative are wood windows, aluminum , are windows with aluminum exterior and wood interior, because aluminino require fewer skills and take advantage of insulating material of wood. On the glass, the most common is to put a 4/10/4, ie two 4mm glass with an air chamber in the middle of 10mm. This may be a mistake, because with little money and can be installed over a more insulating glass, solar control and robust (if it is considered suitable for use), which will ultimately be more profitable.
- Aluminum with thermal break: 650 €
- Bamboo-Aluminium: 1300 €
These prices are approximate, for a window of 160x160cm. without shade. Do not include taxes or the cost of installation.
Conclusions: 
is essential to install windows with high insulation capice. The best option is wood windows from European FSC-certified double glazing and a large inner tube at least 12mm. It is also very important that the windows are swinging, sliding and that do not allow a tight seal.
The use of natural light is a key point in the bio, because it can optimize energy savings, in addition to the many benefits of sunlight to our health and mood. It is therefore very important that all the rooms and hallways of homes having natural lighting. There are many solutions that can be used for this: windows, glass block , skylights, glass doors , etc. One of the most effective and original are the skylights, they give a pleasant indirect light that can illuminate rooms where windows is not possible to either having no walls in contact with the outside or to prevent the installation of windows the north face. This was the case bath upstairs, where we have installed a skylight. 
interesting are commercially available solar systems tubes that let you install skylights even where the beam is not straight. However, we have opted for a simpler and more economical. First we open a hole in the slab, using the space between two joists. Subsequently it has been a structure built with bricks to raise the skylight above the green roof where a skylight has been installed twice. This consists of two elements, one smaller than an upper larger, leaving a camera fit air between them, which improves the isolation from the skylights simple. Finally, inside the skylight will be plastered with plaster and painted white. 
The slope (between 15 º and 20 º) and the distance between the slats, is calculated to facilitate the entry of light in winter, when the sun is lower. ; At the same time preventing the entry of sun in summer when higher, as shown in the image on the left. These calculations were made taking into account the geographic location of the house, orientation and width of the slats, so the tilt of the slats and the distance between them is different in different facades Majorcan home. Having more lean in the south façade and more distance between the slats of the northwest facade.

Other alternatives: 
The wall structure has changed from the original idea. Finally pondremo s solid brick walls, multi-pack, organic hemp insulation , termoarcilla tube and 14 cm. As we are using mortar Bi oCalce Wall 
of Kerakoll is an eco-compatible mortar of lime pure natural NHL 3.5. The Wall s are being built from the inside outwards, so that l late s part to build was the outside of termoarcilla. For this r tendon AN who install scaffolding around the house, where will the isolation and termoarcilla. This allows us to put air into the chamber to the outside insulation and inward, as shown in the picture. This structure enables to optimize the performance of l a camera to ire and isolation. The air temperature buffering acts extr and more from outside, if s and install sticking to the inner wall, and insulation co n touch with the outside, the air chamber loses much of its usefulness d, as happens in most homes. It is very important that the camera no more than 3 or 4 cm, so that there is no mo movements of
