Double log houses

Double timber houses are not the most well-known construction technique. However, that is why it is extremely important to appreciate it, to deal with the projects of one-story and higher houses, with the pros and cons of the approach. It is advisable to study and reviews of such buildings..

Features of construction technology

The construction of a house from a log or a bar is considered a very expensive business, and it is quite reasonable – these materials are not cheap. Also, many people are scared off by the very need to wait 1-2 years until the shrinkage process is completed. However, the double bar technology provides an adequate answer to these challenges. Thanks to it, you can build really quickly, while reducing costs.. The technique itself was developed in Finland and was initially focused on achieving comfort in a harsh climate..

Important: using the double timber method, you can build not only a residential building. It is also suitable for the construction of a bathhouse or an attached veranda..

Outwardly, the cost of building materials is even higher than when building from profiled or glued beams. But it initially took into account the price of insulation, immediately put into the block, and therefore in reality it turns out at least not so expensive as to refuse it just like that. Double timber houses can have complex layouts and an unconventional looking facade..

The real reason for the small spread of this method is the superficial orientation of a number of people to the budget. It is possible to make part of the details of houses from a double bar only on especially accurate woodworking machines controlled by computers. Without such equipment, no serious developer will undertake work..

The technological gap is saturated with a heater that can protect against the spread of steam and extraneous sounds. Multi-layer solution optimally eliminates condensation and helps to conserve heat.

The beam is formed mainly from pine and spruce wood.. Its lightness, cheapness and ease of processing deservedly attract attention. Beforehand, the tree is supposed to be dried in a convection chamber. This method guarantees high strength and protection against decay. Lumber will not be particularly prone to cracking.

After processing on the machine, the timber gets a strictly specified shape and profile, acquires a smooth surface. Slicing of spikes and grooves is definitely practiced, then forming an integral “thorn-groove” complex. This solution has the advantage of eliminating the need for inter-row insulation, usually used in log buildings. Cup-shaped corner joints are guaranteed to prevent freezing of the corner and the occurrence of drafts. In most cases, the main insulation is provided not by ecowool, but by mineral wool.

Good ecowool has:

  • attractive appearance;
  • carefully worked out natural composition;
  • the ability to provide air circulation without moisture retention, which minimizes the need for vapor barriers;
  • increased efficiency in terms of protection against extraneous sounds.

Choosing a good building material supplier is critical. Sometimes they even have to be transported from neighboring regions – but the result is worth it. Arrangement of water supply and sewerage systems is carried out according to the usual option.

The foundation is most often built from piles. The harness is formed from a dry board treated with fire retardants. Sometimes, following the instructions from the manufacturer of home kits, you can even assemble a dwelling on your own..

If for some reason the screw foundation does not suit you, you need to pay attention to the shallow tape. Vapor barrier in some projects is created exclusively inside the floors. Additional vapor barriers elsewhere depend on the personal preference of developers. Therefore, it is always necessary to stipulate this moment in the design process, so as not to redo everything in a fire order during the construction itself..

Warming is usually carried out at positive air temperatures.

Advantages and disadvantages

When erecting a house from a double beam, there is no doubt about its factory quality.. The latest generation industrial equipment allows achieving very high technological characteristics. No handicraft industry can provide such a level. It takes about 14 days to produce a wall kit, and the same amount is spent on assembling the walls – therefore, a house box, ready in a month, is unlikely to be surprising. With the parameters of the material itself and structure comparable to the use of glued profiled timber, the double timber technology instantly saves 20-30%.

With further use, much better thermal protection is already guaranteed by default – heat leakage is reduced by 50%. You can build a house all year round, even on frosty days. No special equipment is required for construction work using the double beam technology. Since the frame is relatively light, foundation construction is also simplified..

After the walls are erected, their outer surface practically does not require finishing – even applying paint is not always necessary.

Since communications for normal life are in the walls, they will not bother people and force them to look for some kind of camouflage methods. Sanded walls can be immediately painted or varnished if desired. The seams are sealed and do not need caulking. This circumstance makes a double log house especially pleasant compared to simple log cabins of the traditional type.. Correctly performed chamber drying can reduce shrinkage on an annualized basis by up to 3%, and under favorable conditions – up to 2%.

But even such an attractive technology has its flaws:

  • you have to very carefully select the material;
  • when using poorly dried wood, the uniformity of shrinkage is disturbed, cracks and even distortions may occur;
  • there is a danger of insulation shrinkage – if it is bad or laid in violation of the rules;
  • it is almost impossible to repair a house built according to the double beam technique without resorting to professionals.

Projects

Now it is useful to consider what the houses themselves are from a double bar. One of the options for one-story buildings includes a 14-meter terrace. The living area in this project is a little less than 28 sq. m. Tambour measuring 4.25 sq. m more than in many other designs. There are two living rooms with a size of about 8 m2.

Additionally there is:

  • kitchen and dining area;
  • hall;
  • hallway;
  • bathroom.

An alternative solution involves arranging a larger home – here you can get into the technical room right from the porch. Another utility room and laundry room are only accessible from the kitchen. To get into the kitchen itself from the outside, you will have to go through the vestibule and hall; the kitchen area is separated from the guest space. Additionally, the house provided for:

  • four bedrooms;
  • bathroom;
  • tiny bathroom.

But using the double beam technology, a two-story house can also be built..

In one of the options, it starts with a 15.7 sq. m. From there you can enter the 24-meter living room and then into the 10-meter hall. What is noteworthy, you can only get into the room next to the living room through the hallway. A kitchen and a bathroom were also allocated on the first floor..

At the second level, houses are equipped with:

  • 3 living rooms;
  • bathroom;
  • balcony.

The alternative involves the arrangement of a dwelling of a more complex shape.. On one side there is a separate porch leading to the furnace with an area of ​​5.4 sq. m. Equipped with a very large – 28.3 sq. m – living room. Terraces of the same shape and area are displayed on either side of it.

There is also:

  • hall;
  • bedroom;
  • kitchen-dining room;
  • bathroom;
  • vestibule.

The second floor was equipped with a hall in the same way. But it also contains:

  • a pair of bedrooms;
  • bathroom;
  • the second light.

Review overview

The assessments emphasize the lack of prevalence of the technology and the fact that many people judge it only from photographs. Negative reviews are associated in most cases with a violation of technology and with the use of low-quality heaters.

It is very pleasant that joinery and carpentry work is not needed directly on the object. You can assemble the frame manually, the main thing is to carefully look at what is combined with what.

However, it is unacceptable to build a simple summer house using this technology – the cost of performing all work with sufficient quality will be prohibitively high..

Some developers use a minimum section beam, only slightly surpassing the boards, so that formally, in terms of assortment, it belongs to the required category of sawn timber.. It is these projects that attract with their low cost. However, as you might guess, only at substantial costs it is really possible to guarantee both the optimal thickness of the timber and the exclusion of insulation shrinkage.

If problems are found in an already inhabited house, you just need to blow out additional insulation and resort to some other modifications.

Given the novelty of the technology and the low readiness of most builders for its implementation, we can assume that this is still, rather, an experimental option, and you need to think carefully about all the pros and cons.

Beautiful examples

A double log house can very well be painted in an attractive blue color. In this case, a roof made of red metal tiles is quite acceptable. The elegant terrace equipment allows you to enjoy the comfort and splendor of the surrounding views. The use of an additional porch means increased autonomy of residents from each other.

You can also focus on the complex shape of the structure itself, sheathed with white material. The windows in this project are small, but very expressive. Some of them also have a complex shape. Elegant lighting also plays a role..

Another option is to use a simple woody color. The roof also has a rather complex configuration and is covered with dark metal tiles..
