An essential element of construction, the frame is associated with permanence and stability. Indeed, on its assembly depends the roof. It is a fundamental part, putting the construction away from air and rain, so it is important to choose the material it is made of. Two possibilities are then offered: the metal frame or the wooden frame. The specific qualities of each will determine the style of the work. Find more articles on the theme: Structural work quotes
Metal frame, the triumph of steel
Choosing a metal frame amounts to electing steel as a building material. Famous for its implementation in the Eiffel Tower, it offers undeniable advantages. Alloy of iron and carbon, it combines great mechanical resistance allowing it to cross large spans and a great lightness making it easy to handle on site. With fewer elements assembled more quickly, the metal frame reduces construction costs as well as delays. Giving the building a modern character, it is also part of an evolutionary logic. Over the years, the house will easily support extensions and modifications.
Traditional frame, wood for millennia
The traditional frame has been made of wood for millennia. Combining the qualities of resistance, solidity, insulation, the species to choose will take into consideration the region of construction. Each offers its own qualities. The oak for its hardness, the pine for its resistance, the chestnut for its longevity give incomparable elements for the construction of the frame. Made of solid wood of large section, the frame assembles the trusses, purlins, slats and rafters according to the rules of the art by tenons and mortises. With a classic and massive structure, the traditional frame making it possible to create large volumes has the advantage of making the attic suitable for conversion. In the collective imagination, she embodies a structural and aesthetic ideal retaining its power of seduction.
Industrial structure, an undeniable practical spirit
Requiring shorter construction times, the industrial frame is made up of small farmhouses, reconstituted wood structures forming trellises. Prefabricated in the factory, they are then placed next to each other with a spacing of about 60 cm on the site. This process, which appeared in the United States in the 1950s, uses small sections, making the structure light. Favoring pine for its small thickness, the industrial frame requires only a simplified installation: construction costs are thus reduced. However, some disadvantages exist. Not only does it offer less fire resistance, but it has no evolutionary potential. Its roof space will remain forever lost.
