Which house is better - from timber or frame? Which house is warmer? Construction technology
For several decades, the debate about which house is better - from a timber or frame one, does not abate. You can evaluate it if you consider several criteria by comparing the frame structures and buildings of timber. This will evaluate the advantages and disadvantages of each option, making the right choice.
Which house is cheaper
As practice shows, the construction of a frame house is approximately 30% cheaper compared to the construction of timber. This is due to the fact that the first option is based on a well-cut edged board, which is two and sometimes three times cheaper than a bar. Among other things, the cost of profiled or glued timber is higher compared to double or sawn. This difference in cost is due to the manufacture of edged boards and beams. These manipulations are carried out using the same technology, but the timber goes 5 times more.If we are talking about a double bar, the technology is more complex, but the cost of the material is comparable to those that go to the construction of a frame structure.
In order to make glued laminated timber, sawn timber waste is used, but the production technology is more complex, it involves a greater number of operations, all this increases the cost price of glued laminated timber.
A little more about the cost
If you decide what house is better - from timber or frame, you should remember that the construction of the latter is accompanied by the need to purchase plating and heat insulation. As a rule, in the role of insulation used:
- mineral wool;
- granulated polystyrene.
These materials are much cheaper than timber, and to save it, a beam of small section is used, which then requires thermal insulation. This allows you to slightly reduce the difference in cost, but it can not be less than 20%. If the basis of comparison is to take the cost, then in this matter the frame building is leading.
Construction Technology Comparison
Quite often modern consumers decide the question of which house is better - from a bar or frame.If the work is done independently, then it will be easier to build a house from a bar, because there are fewer nodes in it, and the construction of a frame structure involves combining many elements, this should include:
- diagonal and horizontal lintels;
- vertical carrier boards;
- metal corners.
The latter will perform the function of connecting elements. As soon as the framing is completed, it is necessary to fill the hollow space with thermal insulation and strengthen the finish, which increases the complexity of the process. According to this parameter, it can be argued that a house from a bar will be better than its opponent.
Which house is warmer
If you also still can not decide which house is better - from timber or frame, then you should compare one more criterion, which is expressed in heat loss. The solution to this issue will depend on many factors. If you compare the buildings with the same thickness of the walls, the heat loss of frame housing will be much lower, you can count on the difference in the range from 50 to 90%.
This is due to the fact that the thermal conductivity of the material is higher in comparison with the thermally insulated material, which indicates that with the same thickness of the walls in the frame building it will be more comfortable in winter.If the question of which house is warmer - frame or out of timber is important to you, then it is better to choose a frame home, because it will be much more comfortable in it, and the costs will be much less or the same as when building a house from a beam.
Resistance to adverse effects
If you want to build a house for permanent residence, but you can not decide what will be the basis of its walls - a frame or timber, then you should compare these two materials also in terms of resistance to external effects. It refers to fire, flood, wind and earthquakes. According to this factor, it is quite difficult to compare the described opponents, because the stability will depend on the measures taken, which can increase the rigidity and strength of the structure.
When it comes to log buildings, they use wooden wedges and expansion joints that connect the crowns. Whereas in a frame house, diagonal bridges are used to increase strength and rigidity, which together with vertical and horizontal planks form a triangle. Fire resistance also does not depend on the type of construction, this factor will be influenced by the correctness of sawn timber processing. If wind resistance is important to you, then you only need to strengthen the foundation.Timber and frame houses will cope equally with gusts of wind up to 50 meters per second, if they are protected from damage and built according to technology.
When choosing a house for permanent residence, it is necessary to pay attention also to how comfortable the indoor microclimate will be. According to this parameter, the timber construction is better, since the wood absorbs the excess moisture in the rooms and brings it outside, which is much more effective compared to the building that is sheathed and insulated.
For this reason, installation of forced and natural ventilation systems is required in the frame house, which are designed to fill the room with oxygen and remove excess moisture. This indicates that the cost of creating such systems will increase, because to ventilate the house from a bar it will be enough just to open the window.
When houses from profiled timber are additionally insulated from the outside, then they should be supplied with ventilation systems, because the vapor permeability of wood, insulation and plating will be less. According to this parameter, the best houses are from timber, but only those whose walls have a rather impressive thickness that does not require additional insulation.
Comparison of the complexity of repair of bearing walls
The walls of the frame house, as well as buildings made of timber, must be periodically repaired. In the first case, for this purpose it is necessary to dismantle the casing, remove the insulation and replace the damaged carrier board, which is located diagonally or horizontally. At the next stage, a heater is installed in its place, and the wall is again covered with a covering.
Carrying out such work does not imply the need to use special equipment, but only highly skilled builders will be able to cope with the task. But when repairing a house from a bar, you should be guided by other rules that indicate the need to raise the crown above what needs to be replaced. For this, a jack is used. The next step will be the removal of a faulty beam, as well as the laying of the whole element. Difficulties may arise if the construction of the crowns were connected by shrinkage compensators or wooden wedges. In this regard, the walls of the frame house is much easier to repair.
Construction technology frame house
The foundation for a frame house can be any:
- pile and screw;
If you decide to use the second foundation construction technology, then you should prepare piles that can be installed independently. If they have an impressive diameter, you will have to use special equipment.
At the first stage, the plot is laid out, the ground is leveled so that the piles can be set on a level. They should be placed in the corners, deepening to 0.5 m. At the final stage, you will need to trim the pile to the desired level.
Such a foundation for a frame house involves the subsequent concreting of supports and the installation of caps. The master will have to make a harness using square bars. Before mounting the upper part of the pile are processed with mastic, after they should be laid roofing material in two layers. The harness is strengthened with fastening screws. Only then can you proceed to the device of the subfloor, for which lags are used.
Frame houses, the construction technology of which is described in the article, must be erected from the board, which is first installed in the form of corner posts. It is possible to strengthen the elements with the help of steel corners.The next step is to install the remaining racks. In the corners, the bars are strengthened by cutting, in other places by steel corners. This knot will be the top trim. To give the structure strength, it is necessary to install diagonal braces.
Frame houses, the construction technology of which should be studied by you, if you plan to carry out the construction yourself, suggest the presence of ceiling beams, which are installed by cutting, using steel corners or perforated brackets. The next step is to install the truss system and exterior trim. For decorating walls, you can use stone, siding, or any other material that is installed on the batten. Warming of the frame house is carried out with the help of mineral wool, which is supplemented with a vapor barrier film. It is necessary to warm not only walls, but also a roof, a floor, and also overlappings.
Technology of building a house from a bar
If you want to build a cellar or basement in the house, then it is best to prefer a strip foundation. When loose, silty and wet soil fit screw piles.Small buildings are usually installed on a solid slab foundation. After the base is ready, it is possible to proceed to laying the first crown, this is done on a double layer of roll insulation, which may include roofing material and bitumen.
Every detail of the house should be treated with antiseptic. To prevent fires, you can also use flame retardants. The first board must be firmly fixed to the foundation through a layer of waterproofing. Thermal insulation lumber construction is required, as well as insulation of the frame house. To exclude cold bridges, you can use jute insulation, which is laid between the logs. The roof system will be built on the basis of the mowerlat on which the rafters are laid. Then you can proceed to the laying of vapor barrier and heat insulation layers, as well as covering material.
In order to understand which buildings are better - houses made of profiled timber or buildings erected by frame technology, it is necessary to consider many criteria. Some of them have been highlighted above. A number of experts believe that the comparison in this case is inappropriate, because none of the buildings described can be better or worse, they are simply different.
For example, a frame house will be practical, inexpensive, easier to repair, however, it is possible to organize the right microclimate for a person in it, with some effort.
If the question of whether it is cheaper - a house from a bar or a frame house is important to you, then you should choose the last option, because the first is more expensive but prestigious, and with proper construction you can eliminate unnecessary financial investments and additional efforts. Such a building itself will form a good indoor microclimate. Based on these beliefs, it can be argued that for some consumers the frame construction will be better, while for others it will be a building of timber.
