Technology of LGSF

LGSF construction has a long history. Contrary to popular belief, it first appeared in the mid-19th century in the United States; but the development of cold-molded structures slowed in the early 20th century due to the lack of the necessary regulatory framework.

Today, frame house construction is the main type of low-rise construction in Scandinavia, Finland, Germany, and the United States. Every year, more than 1.5 million frame houses are built in North America. This is due to a number of obvious advantages of this technology.

1. High strength and durability. 

Unlike wood, steel is not affected by biological processes (e. g., rotting). The service life of light gauge steel framings exceeds 100 years. They can withstand all the features of our climate: temperature changes, precipitation, winds.


2. Fast construction.

In contrast to buildings from traditional materials, comfortable villages composed of LGSF frame houses can be constructed within a month. Frame houses that use prefabricated parts are lightweight, which in most cases eliminates the need for lifting mechanisms.


3. Independence from weather conditions.
Customers are not limited by weather conditions in the course of construction of frame housing using the LGSF technology.
Due to the absence of wet processes in their construction, the construction team can provide a continuous workflow.


4. Low cost.
The final cost of a frame house constructed with the LGSF technology is lower than that of a house from traditional building materials: bricks, concrete blocks, conventional bricks etc.


5. High resistance to heat loss.

High thermal insulation properties of the building are provided by the fact that, unlike that of the buildings made of brick or wood, the entire thickness of the wall is filled with highly efficient heat-insulating material, which can significantly reduce the heating costs of the building. In terms of thermal resistance, a 25 cm LGSF frame wall equals a 1.5 m masonry wall.


6. Earthquake and fire safety.

Frame houses that use LGSF as a carrier system can withstand seismic loads of up to 8.0 on the Richter scale. Mineral wool which is used as an insulation material can be used at a wide range of  temperatures (from -60 oC to +400 oC). Thus, the structures do not accumulate moisture, are protected against corrosive acidic environment, high temperatures and fire, and are not susceptible to rodent and microorganism infestation.


7. Eco-friendliness.

LGSF frames are insulated with mineral wool, which is an environmentally friendly material.

In addition, steel components of LGSF frames can be reused, which is a big environmentally friendly advantage. This advantage is also actively leveraged by extractive industries in rotational camp construction.


8. No shrinkage.

Due to their lightness, LGSF buildings are not subject to shrinkage observed in the construction of brick and aerated concrete houses.


9. Wide architectural possibilities.

LGSF may cover large bays of up to 24 m without intermediate supports. This allows for the best use of the building internal space as well as for the re-planning possibilities.
