Differences between a frame house in the USA and Finland
The homeland of the frame method of building a house is Germany. Then this method became popular in Canada, America, Finland. Later in Russia. Finnish technology differs at times from American and Canadian ones. Many questions arise, and the most important one: which is better and more profitable?
In America, the zip system (house cladding) is popular. This is a kind of OSB sheets, treated from the outside with a special composition against wetting and for thermal insulation. The joints between the slabs are glued with a special tape.
In America, they do not disdain and collect the frame on black uncoated nails. From this, not beautiful smudges arise. They don't do that in Finland.
What good is seen in America at a construction site. Almost everywhere there is a toolbox that is locked. The box is on 4 wheels and can be rolled (if necessary) to any place. They come in different sizes. No need to carry tools with you, everything is in one place in the drawer.
I also found another interesting detail in American housing construction. All residents are afraid of hurricanes, tornadoes, strong winds, so the frame house is fastened with 2 mm anchor nails. iron plates. This is done to strengthen the frame, which I personally really like.
But one point seemed dubious. Why put together 3-5 racks to each other?
They say this is for reinforcement (especially around door / window openings). But there is a gap between them and there is no insulation. Cold will pass through such cracks, which will lead to wetting and ultimately rotting of the boards.
For fastening the rafter system, metal corners, bolts, clamps, hinges and perforated plates are used. This is done for quick assembly.
Another difference: a Finnish frame house can be obtained in 2-3 weeks. Canadian or American in months. The Finns make the entire walls at the factory. They are delivered to the construction site with finished insulation and rough finishing, window openings.
Dry wood is used everywhere in the construction of a frame house. In some places, plywood is used to stiffen the frame.
The Finns mostly have a living room upstairs, while the Americans have a bedroom. Now Americans have a new fashion: to make a cinema on the top floor.
Americans use double top strapping for slab sheathing. Also for amplification? The Finns don't do that.
