FAQS
WHAT TYPES OF EXTERNAL FINISHES OFRECE Openhouse?
Our houses are built with ventilated facade, this means that between the wall and the outer bearing is an air chamber. The siding is always composed of parts such as Werzalit, natural wood, stone or mortar layer applied on cement-gypsum panels especially for exteriors.
Continually looking at finding new solutions to extend the range of finishes such as brick, stone, plastics, etc..

WHAT THERMAL / ACOUSTIC ARE THE VILLAS OF OPENHOUSE?
Building wooden facade with a layered solution that enables our chalets have a degree of thermal insulation / sound very high. The front wall has a thickness of 100mm of rock wool, besides the already commented 35mm tube. These two features raise the level of insulation far above that required by the new rules of the Technical Code. Add the wood as a structural element that provides improved performance and is a little material conductor of heat and sound.
Sound absorption is also enhanced by the same aspects of the thermal, the key is the bulk of the insulating material.
 
It is said that the wooden chalets are more insulating, how can it be?
Indeed, the difference in the level of insulation of a house not given the material, whether wood or brick, what is the insulation that is placed. In the case of wooden houses Openhouse the facades of the structure has a thickness of 120mm, which is inserted into the gaps of the half-panels of rock wool 100mm, plus 35mm ventilated chamber. This system means that we are well above levels of thermal insulation compared to a traditional system, simply because they never put a bulk of these dimensions. On deck we use the same system with a camera under the tiles and thermal insulation of rock wool in this case 80mm.
Sound absorption is also enhanced by the same aspects of the thermal, the key is the bulk of the insulating material.
 
WHAT TYPE OF HEATING RECOMMEND?
In chalets Openhouse can install any type of heating, as we adapt during the design phase and project, although all the named heat recommend blue for its energy efficiency and the radiant floor system for your comfort.

WHAT IS THE DIFFERENCE BETWEEN THE BUILDING WITH BRICKS AND BUILDING TYPE Openhouse?
Openhouse system is a system used throughout northern Europe and North America. Its structure is based on load-bearing walls of light wood lattice formed by uprights and cross members 120x47mm .. Addition to parts of structure porched lights to save big without intermediate walls, the wooden structure allows for complete design flexibility, increased energy savings and significant reductions in the cost of labor.
Another difference is that this type of construction uses little water as a dry work therefore does not require waiting 28 days to the fragmentation wrought-contained and has no humidity measurements of the walls have a millimeter accuracy.

ADDITION OF HOUSES, WHAT OTHER BUILDINGS USING STRUCTURE OF WOOD?
The wooden structure is used exactly the same as those of steel or concrete. Both in Spain and other countries we can find schools, hospitals, buildings, sporting, church, etc.
 
HOW MANY HEIGHTS CAN BE DONE AT HOME?
Openhouse system by engaging the vast majority of buildings to house an isolated maximum recommended height of 3 storeys, the last one under-cover. In other countries of northern and eastern Europe have come to successful trials in multifamily buildings of 4 floors.
 
How many types of window is used?
Windows and all other exterior and interior woodwork are of free choice. Generally, we use aluminum, PVC and wood mostly because we are also manufacturers.
 
WHAT IS THE CONSTRUCTION OF FLEXIBLE SYSTEM?
Openhouse is one of the few companies that offer homes to measure. This requires resources and expertise high, but is also one of our great advantages as we have qualified personnel in our technical department in our factory. The system has all the flexibility that might require a system. This is demonstrated by the fact that the customer can bring their own plans without the need for prior consultation with our technicians. We build houses, townhouses, restaurants, etc..
 
CAN YOU HAVE A BASEMENT?
The basement can be a part of the foundation or build an additional building on. Openhouse has done both since the wall in contact with the ground is never made of wood, to avoid sudden changes in moisture content of wood and undermine their resistance. The material which makes up the basement is always either reinforced concrete or precast concrete blocks, depending on the structural function and provided with impermeable containment in extradós.

HOW LONG CAN SUCH A VILLA?
Such buildings exist in various countries centuries ago. In Finland you can find churches in 1626, Spain built in the thirteenth century.
Still constructions made Openhouse is normally isolated house was designed and constructed to last a minimum of 50 years which is what predisposes the LOE. It is clear that any construction done with a minimum of hardship and subsequent proper maintenance will last a lot longer.

FROM THE ECOLOGICAL POINT OF VIEW, ACQUIRING A DWELLING OF THIS TYPE CONTRIBUTE TO DEFORESTATION?
Contrary to what may happen in other countries, purchasing this type of housing contributes to reforestation. The wood used comes from forests Openhouse © East European countries have a law that is very respectful with the environment. For every tree that was planted two new logging. In recent years these forests have grown by 8%. Although this percentage seems small, it must be borne in mind that these forests occupy 80% of the territory and the potential volume of wood would be 15 times around the world with a wall of a meter wide and three meters high. Represents an 8% return over the Earth. Do not forget that the forest is a supplier of renewable raw materials, trees grow, live and die synchronously and cyclically driven by the sun.
 
WHAT ARE THESE BENEFITS ECOLOGICAL HOUSES?
Many. Firstly to help reforestation of forests. Secondly, the fabrication of parts using less energy. Thirdly helps conserve the ozone layer since the winter requires less heat and less CO2 is emitted. Fourthly the use of wood avoids the use of non-regenerative natural resources like oil and metals, so that they can be the legacy for future generations. Fifth the energy used in the processing of wood, called embedded energy is much lower than that of other substitutes such as steel, concrete, aluminum, and plastic. It is therefore an industry with low energy consumption. Sixthly wood is a CO2 tank that stores 0.9 tons of CO2 per cubic meter of wood throughout its life cycle. In seventh place is a healthy wood, and which does not emit harmful substances to human health. It is also a material which regulates moisture in the air, creating a healthy environment and comfort.

MY CONCERN IS THE LOW STRENGTH OF THE WOODEN CHALETS.
There is no reason for that fear. In Spain as in many European countries and Americans can find buildings with wooden structure with several centuries old. We must bear in mind that in those times were not known special treatment, nor analyzed the types of timber or parts of trees most suitable for construction, nor did extensive calculations of structure. With new technology available, this type of construction we can ensure a life span of many generations. There is now a Spanish regulations (CTE-SE M) on wooden buildings. Openhouse meets these rules in every project it undertakes.
 
HOW ARE TREATED WOOD AGAINST THE MOISTURE AND INSECTS?
The wood has been specially selected for use in construction. The wood has been dried previously sawmill supplier and stored in our factory in a special place for conservation and final drying. Is applied to a bath of insecticide-fungicide (against insects) before preparing the half-.
 
DREAM WALLS ARE THE GAPS?
The walls are not hollow. All are filled with mineral wool rock. Undoubtedly material sounds different.
 
CAN I BECOME THINNER INTERNAL PARTITIONS?
You can build the interior walls thinner but lose capacity and insulation resistance. We do not recommend. Furthermore there is no significant savings because we use the partitions for each half-minimum that can be manufactured by numerical control machine, which needs a minimum thickness of wood.
 
WHAT KIND OF FOUNDATION IS USED FOR THIS TYPE OF HOUSES?
Theoretically, a foundation could be used for a lighter than traditional construction but to avoid any doubt about that - and given that the savings are minimal - a foundation is calculated according to the requirements of the Technical Building Code, resulting in nearly a foundation identical to the other building systems.
 
IS IT POSSIBLE TO HAVE THICKER WALLS?
The bulk of the walls depends on the coatings are applied. The wooden lattice structure is always the same with a bulk of 120mm., From here we can add different thicknesses on the inner surface of the outer face as the most common being the following (from outer to inner): 18mm © werzalit + 35mm ventilated air + 0.5 mm waterproof foil vapor barrier-timbered + 120mm (in 20mm inner tube and 100mm of insulation) + 12mm + 12mm OSB board of wood rabbet pine.
To order can be made thicker walls in their structure, but it is totally unnecessary.

WHAT THE BANKS MAKE DRAWBACKS TO GIVE MORTAGAGE TO A WOODEN CHATET?
None. This type of accommodation is fully mortgaged. On the contrary, the fact that they can build in a few months increases the confidence of the bank that the transaction will come to fruition.
 
WHAT PROBLEMS EXIST WITH INSURANCE? Suppose that the premiums will be higher.
No. The premiums in Spain are the same. In other countries with more experience in these systems are cheaper.

WHAT HAPPENS TO THE RESCUE? IS SURE TO HAVE A HIGHER RISK THAN A TRADITIONAL CONSTRUCTION
The causes of fire are never for the structure. The fire risk is present in carpets, furniture, curtains, etc.. The fire resistance of the structure before its collapse is greater than in a metal structure and a structure in which the factory walls, the wood has a coefficient of heat conductivity, very low, especially in the direction perpendicular to the fiber which means that if the section of the piece is large escuadrías burn only the outer layers without penetrating the heat in the interior. The wooden structures under the action of the fire did not expand and therefore no displacement of supports, or movements, it does not collapse by facilitating the work of safety and rescue. Another aspect to consider is that in the early stages of the fire wood increases its mechanical resistance by heat to leave dehydrating. For every 1% loss of moisture, grows by 4% the compressive strength and a 2% resistance to bending. Offset this loss of moisture, initially, the loss of strength due to lower section produced on burning.

IT'S HARD TO HANG ON THE WALL BECAUSE SOME NEEDED SPECIAL SCREWS.
Special screws are only needed when the walls are covered with plasterboard. We normally recommend that particle board and OSB oriented rabbet wood when it is finished in wood and cement-gypsum panels when finished painting. The last panel is much greater mechanical strength and weight to set walls do not need special tortilleria.
 
HOW DO I FIX THE MAINTENANCE NORMAL TO ANY HOUSING?
The maintenance of any housing can be ordered from any professional. In any case, we have a safe-keeping, which means paying a small annual amount to cover routine maintenance.
 
WHAT ARE THE DEFECTS OF THESE HOMES?
The defect of these homes may not recommend changes in the work. That does not mean that they can not reform, it means that as we try to reduce the time of execution of works to a minimum and the cost of labor, any increase in the mean time and cost.
 
THESE HOMES NEED MORE THAN A BUILDING MAINTENANCE POSTPAY?
The maintenance of these houses do not require any special treatment. For the chalets are finished in enfoscado a monolayer or require less maintenance than a brick. In the case of Werzalit maintenance is reduced to zero, and if the wood just needs to be varnished every two or three years at the beginning of its construction, and annually thereafter.

I UNDERSTAND THAT THE VILLAS OF WOOD WAS BUILT IN LESS TIME BUT HOW WOULD THAT AFFECT THE OVER?
Openhouse structures can be lifted in 15-20 days. Herein lies the biggest difference in time. This is the great saving in time of electrical installations, placement of windows, doors, etc.. Nor is time of drying floors, walls, etc.. Finishes without equal in all systems.
 
HOW TO BUILD THE HOUSE IS PROPERLY?
All chalets are fitted by factory personnel who know the building elements to perfection. In all the work is received unannounced visits from the representative of the manufacturer to see that everything is done properly. Moreover, the architect and regularly supervise rigger work.
 
HOW LONG SHOULD I WAIT OR PAINTING PAPER?
You can start to paint or wallpaper on the same day it ends to make the partitions and walls. This system does not require drying.
 
ARE THERE MANY PROBLEMS HUMIDITY?
One of the great advantages of these homes are not using water, and materials that lead humidities. All housing has a vapor barrier to prevent passage of moisture or condensation. During the construction of a waterproof forjado place to prevent the passage of moisture.
 
WHAT CHANGES CAN BE DONE DURING THE WORKS?
It is recommended minimum. Maybe the flaw in the system. Able to commit to a price and time can not make changes. Furthermore, the structure that is factory was done according to your instructions and the technical project. What it does do is to revise as necessary the project to be very clear ideas of what is required.
 
WHAT HAPPENS IF IT RAINS DURING CONSTRUCTION?
The risk we have of rain during construction will be limited to the construction of the deck. This is approximately 10 days depending on the model home. In any case if a rain or two days, nothing happens. For this reason we have developed a system for rapid construction.

MY PLOT IS IN AN AREA VERY WET IS IT POSSIBLE TO BUILD IN THIS AREA?
There is no limitation for this reason. It should be remembered that over the years, most northern European countries are covered with snow which melts at the end and does not affect housing. In the months when ice cream is not all, houses are surrounded by sea or by one of the 188,000 lakes that have for example Finland. Moreover, during the design phase, it takes into account various parameters to avoid problems with humidity and condensation in the housing provided meets the requirements of the Technical Building Code.

WHAT IS THE PRICE PER SQUARE METER FOR EVERY TYPE OF CONSTRUCTION?
The calculation of the price per square meter of a house varies greatly according to their design and finishes. In our information pack you will find a table to help you calculate the price of the house you want. The average home can be completed at about 800-900 € / m² in a standard model.
 
WHAT OTHER SAVING SYSTEM EXISTS IN THIS BUILDING?
The savings from this type of construction is seen in differences in quality, saving time (soon come to live so you can pay less rent or sell your old home before) and manpower mainly for the speed of construction . The big savings come later with the use of housing as the power consumption is approximately 50% of a house brick. Where there is significant saving finishes (bathroom, faucets, kitchen, tiles, etc ...) that you are elected in any other case.
 
ARE THESE CHALETS MUCH CHEAPER?
Quality being equal these villas are cheaper. This difference is less noticeable because it must be borne in mind that the foundations are almost like those of a house built with traditional materials. Permanent loads and overloads taken into account to calculate the structure are those that demand the CTE and makes only be noticeable in the lighter weight of the cover and on the facades, but in a very small percentage. In any case, despite a reasonable quality difference in our favor, there is a price difference caused by the use of child labor in the assembly.

WHAT ARE THE BENEFITS OF THIS STRUCTURE?
The main advantages of this type of structure are: the total design flexibility, speed of play, accurate measurements, the absence of water on site, great isolation, quality control in factory, the high quality in their different elements, the vapor barrier around the exterior and the savings in manpower. Another comment that may seem hard to believe, but it is extremely important in Spain, the greatest resistance to earthquakes is a key reason for its use in Japan, this is due to arriostrado of all elements of the half-bearing.
 
CHALET IS A PREFABRICATED?
What do you mean by pre? If you charge a door to a carpenter to measure, when it comes to his new house, that door is fabricated or not? Prefabrication can be considered to all parts of any house except the foundations and floors that are made on site. Brick, tiles, all have a part of prefabrication. The idea of prefab equals bad, just a cheap, these days are excluded. Quality control has now reached a very important role in all industries and the construction does not escape from it. It is always safest car produced in a factory with the controls mounted on the pieces home for a mechanical expert. If, moreover, not an expert mechanic and not an engineer with a great sense of responsibility, to assume the risks are high. The traditional building has plenty of examples, some of whom you know.
 
WHY IS MOST USED THIS TYPE OF HOUSING IN NORTHERN EUROPE?
They are used in northern Europe - and America - they have more wood and its environmental conditions because they can not take nine months to build. They also require a higher capacity of thermal insulation for the winter. In these times where the sustainability criteria are gaining more importance and awareness by the general public is creating an increased interest in this type of construction by both private customers and by the government.

¿IS IT POSSIBLE TO MAKE CHANGES?
This system allows all sorts of reforms with the same limitations as any system. Ie you can not remove the structure of the housing without replacing it with another.

WILL YOU IN LICENSING, DRAFT, ETC.
We must distinguish the different legal procedures to build a house. A building permit is requested by the developer, who is usually the customer in the relevant municipality. The technical project has to make an architect. Openhouse @ has its own architect and external that have great experience in this type of construction, but it may be proposed by the client.
 
LICENSE IS REQUIRED FOR CONSTRUCTION, PROJECT, ETC.
Yes, all mobile homes that are not require the same permissions and licenses to any system. Among other reasons, it makes mortgages.
