What are the prefabricated houses using frame technology: Canadian and Finnish

Prefabricated frame houses appeared in our life not so long ago. Their excellent performance, affordable price and relatively quick construction made this type of building extremely popular.

Now buildings of this type are being built almost everywhere. [contents ]

A bit of history about prefabricated houses for permanent residence

If you go deeper into the past, it becomes obvious that frame construction technology came to us from Canada (Canadian houses). Residents of the country duly appreciated such housing, warm, cozy and pre-fabricated.

The following factors contributed to the rejection of the construction of standard houses using log cabins and the beginning of the construction of prefabricated frame structures:

• A decrease in the number of forests makes one think about alternative methods of construction;
• Dimensions of buildings solid wood limited by the length of the available logs; prefabricated buildings are devoid of this drawback;

Applying this technology, builders manage to erect sufficiently large dwellings with many rooms and an original layout. The excellent energy-efficient qualities of these buildings, their efficiency and budget have brought this method of housing construction to the first place in the central and also northern regions of Russia.

Prefabricated structures: technologies

This technology is not one, there are several types of them. The most common ones are German, Canadian and Finnish.

• Canadian technology is as follows. First, the frame is knocked together, which will then be sheathed with chipboard or OSI plates. The technology has its own nuances, so certain factors can cause a decrease in the quality of construction or an increase in its terms.
• According to the Finnish method , construction is carried out in a similar way. In special factories, entire modules are made (these can be already rooms, or only walls), which are assembled into a whole building at the location of the future house.

• German technology (half-timbered houses) involves the manufacture of a special building kit (in an industrial way). The latter is a frame completely wired into a panel. It is delivered to the construction site and, like a constructor, is assembled.

Moving such kits is much easier and cheaper than similar Canadian items.

LSTK.Prefabricated structures

Probably, many are already familiar with the aforementioned abbreviation. It stands for simple, and means steel thin-walled easily erected structures. In general, this technique is similar to that described previously, with the exception of one important and fundamental feature.

Instead of wood, they use steel (metal houses).

The frame is made of strong steel profiles, and lightweight metal sheets are also used as casing.

Housing built according to this method is very comfortable for housing. The houses are quite environmentally friendly, quite lightweight and easy to build, retain heat well . The buildings have standard and stable dimensions, all elements are manufactured in a factory way, which ensures their high quality. Their transportation is thought out and does not cause any difficulties. Disadvantages are:

• Fragility.

  But this drawback can be solved by using special steel, on which a thicker zinc layer is applied. Its consumption should be at least 350 grams per square of area.

• Thin walls. They are actually quite malleable, and they resist damage very well.

LSTK quickly gained wide popularity and won a worthy place in the market.

In some places, they begin to crowd out timber frame houses, and today this technology is used all over the world.

Frame houses - prefabricated?

Potential homeowners want to know if the title is true. How quickly can such a structure actually be erected? Depends on how much you want to save on building a house. I must say that this largely depends on the builders, or rather, even on the specific construction company.

For some, everything is always ready, a well-coordinated team of professionals is just waiting for the command to start.

Others will draw up papers, order building materials, wait for permits ...

Prefabricated frame buildings: advantages

The indisputable advantages of buildings erected using frame technologies are the following:

• Erection speed. The structure can be assembled as quickly as possible.

  No other technology makes it possible to build a cottage so quickly.

• Accuracy . Individual parts of buildings, or large elements, are manufactured industrially, in a factory. Therefore, they absolutely match each other. All that remains for the masters on the site is, strictly following the instructions, to assemble them into a single whole.

  This does not apply to Canadian technology, since it is used for assembly directly on the site.

• Budgetary. The erection of frame structures is much cheaper for customers than the construction of conventional cottages. This type of dwelling is more affordable for the general population.
• Construction progress does not depend on the season or the ambient temperature.

• Little waste. Finished blocks and structures arrive at the construction site in fact in finished form. On-site work is underway to fine-tune and assemble them.
• Lightweight foundation. The design features of the frame structure eliminate the need to equip a solid foundation foundation.

  The frame itself is rigid enough to withstand various mechanical influences, including seismic ones.

Frame buildings: technology disadvantages

In addition to obvious advantages, prefabricated frame structures have some disadvantages.

• 

  Formaldehyde can be released from building boards. It is recommended to purchase board material of zero or first class of emission of this harmful substance.

• Insufficient thermal mass of the structure.

  Classic buildings made of bricks, logs, beams, concrete can accumulate a sufficient amount of heat. They are able to use this to regulate the internal temperature of the home, smoothing out its daily fluctuations. During the day, the walls heat up, at night they give off their warmth. Lightweight frame structures do not have such properties, so it can be cool in winter and hot in summer. But it is much easier to warm up such a structure to the required degree than the classical one.

• Sometimes such structures are not highly fire resistant. They struggle with this, preferring special fireproof panels, non-combustible foam, various fireproofing impregnations.

Successful mastering of modern technologies of production and installation of prefabricated houses has provided people with ample opportunities. Now, almost everyone can become the owner of light, pre-fabricated and inexpensive housing. The construction of such houses is being actively developed in Finland, Russia, Germany and many other countries.
