Prefabricated houses – “Finnish style” or “Canadian style”?

Which technology is better? This question does not have a clear answer. Each system has its advantages and disadvantages. Let's consider the main ones.

Frame houses are often called "Canadian", although construction using this method was invented in the 20s of the XIX century by the Swedish architect Fredrik Blom. The method was popularized by the Englishman William Manning and ten years later frame houses became known throughout Europe. The idea went with the emigrants to the countries of North America, where it was slightly modified, and after several years re-imported to Europe. And although both methods have much in common, there are also significant differences.

The difference in design

It is believed that "Finnish" houses are more suitable for Ukraine, since our harsh winters are similar to the cold climate of this northern country. The main differences between the Finnish and Canadian systems are that "Canadian" houses are assembled on a frame directly on the construction site, and "Finnish" buildings are delivered to the site in the form of ready-made individual elements.

Common features of both systems include the arrangement of walls, ceilings and attics, the same requirements for heat, water and sound insulation, as well as fire safety issues. Another common feature is the use of high-quality wood in construction. The differences are mainly that "Finnish" houses are assembled from ready-made structural elements, while "Canadian" houses are built on a frame, which provides greater freedom of action and makes it possible to implement individual projects.

Difference in finishing

Both systems have no serious limitations on the external finishing of the facade. It can be plaster, clinker or siding. The walls of both "Finnish" and "Canadian" houses can be additionally insulated with expanded polystyrene, the only difference is that in the case of the "Finnish" technology, the insulation is attached to a wooden lathing. Thus, a ventilation gap is maintained between the wall and the thermal insulation, which helps protect the facade from moisture.
