28 Oct Wood or Steel Framing vs Traditional System
Nowadays, there are many constructive systems with which a house can be built. Which one to choose and why? Wood or steel Framing vs traditional system. The decision on the construction system takes into account many aspects such as: quality, durability, speed or costs. It is important to keep in mind, what result is desired since not every system allows certain finishings.. In addition, the professionalism of the workforce, the materials available and the climate must be taken into account.
Enviromently, dry construction systems such as Steel Framing (steel framework) or Wood Framing (timber framework) are undoubtedly the best option. They save more than 60% of waste, 90% water and low energy use during the construction process. In many cases, a well carried out construction with steel framing or wood framing systems could opt for sustainable certificates such as Passivhaus, LEED or BREEAM
A traditional construction also has the disadvantage of setting or drying times. Another disadvantage is the need to break the walls to incorporate the electricity and plumbing systems. In dry construction systems (Steel or Wood framing), all installations will be carried out in parallel to the placement of plasterboards.
In the traditional system, ceramic or concrete blocks have lower thermal insulation results compared to Steel or Wood Framing. In Steel Framing systems, frames are closed externally by dry cement plates, and filled with acoustic fibre membranes. In addition, the thickness of the walls is smaller and they offer the same result as traditional brick.
However, in hot weather, additional finishes must be included in Steel Framing systems to prevent heat from reaching steel structural frames. This increasing costs slightly.
Every structural system is affected by temperature, either heat or cold. Each system has its regulations for shafts spacing in hydraulic shafts and walls. Same happens to the use of fiber cement in roofs or corrugated tiles. It is important that the openings are strategically arranged with a correct technical development of the project. This implies the need of a professional team with greater knowledge than in a conventional construction. However, systems such as Steel Framing allow to calculate more accurately dilations and greater variations without affecting the building.
The same occurs in the presence of high temperatures such as fire or floods. Although it seems contradictory, a timber-framed system resists fire better than a conventional brick one. The same occurs in a Steel Framing system with higher benefits than in the previous two.
A frequent question is the strength of the materials and their limitations. Corrosion of steel in the Steel Framing system is solved with a galvanized and treated steel. In Wood Framing there is a risk of pests and moisture that could affect the wood reason why wood must be treated correctly to avoid long-term pests. These problems do not affect concrete and brick, although it must also be treated and repaired. It is estimated that the life time of a traditional construction is half that of Steel Framing or Wood Framing.
Condensation and Humidity
It must be taken into account that the light framework systems have hollow walls filled with insulation panels. Such panels could accumulate steam due to internal condensation if correct vapour barriers are not made. A properly installed Steel Framing system manages to seal any unwanted moisture filtration with its steel profile in order to avoid such inconvenience.
In general, each system has its advantages and disadvantages, but undoubtedly light-framed systems are more efficient and their overall costs match those of traditional systems. They offer qualities far superior to a traditional construction with shorter execution times. however, it is true that, for them, a skilled workforce is necessary.
