Advantages of Casas Mundiales Built Prefab Homes Spain in an Earthquake

Not only for Prefab Homes Spain earthquakes are one of the most destructive forces of nature which not only cause the ground to shake violently but can produce additional hazards such as tsunamis, and fires from damaged infrastructure. Of course, the inevitable consequence of seismic activity is the loss of life but, thanks to improvements in design and construction, the modern home is now a far safer environment to be in during an earthquake. Light gauge steel framing is a great example of these improvements, offering very real advantages over traditionally structured buildings in the event of an earthquake.

Light gauge steel framing has actually been used in commercial construction and in some residential buildings for decades so it’s by no means a modern innovation. Today, steel framing is becoming a more viable contender in the prefab home building industry and it has the advantage of a reliable track record over an extended period for consistent performance as a structural material.

Steel is a stable material with consistent chemical attributes. Once the steel stud has been formed, it will remain straight with virtually no change to thickness, width or other dimensional properties. On the other hand, once a tree is harvested, the wood immediately begins to dry and shrink. This drying and shrinking process continues to a lesser degree even after the wood is processed and can be seen as the lumber warps, twists or bows. Inconsistency in the quality of the wood in an individual stud can also result in cracks or weak spots within the prefab home.

Of course, the overall strength of the structure will ultimately depend upon the quality of the connections between the studs. Steel framing typically utilises screws that provide a mechanical locking connection thereby resulting in a very stable frame. In contrast, wood framing connections are made with nails that rely on friction and bending. As the wood further dries and shrinks over time, the amount of friction holding the nail in place within the wood declines.

Steel has a significantly higher strength-to-weight ratio than wood. A steel frame is typically one third the weight of a wood frame and hence damage through inertia will be significantly reduced since there is less weight to move around during an earthquake. The building codes that must be met when constructing steel framed walls are based on more rigorous testing procedures which have been put into place following a number of earthquakes during the last decade.

Steel framing is more likely to maintain its structural integrity over the long-term when compared to wood. Steel is impervious to rot, termites and other pests that can slowly and quietly degrade the structural integrity of wood frames, eventually lessening the prefab home’s ability to withstand seismic forces.

Steel is non-combustible and hence cannot contribute fuel to help the spread of fire. This can be an important factor if the destruction from an earthquake leads to fires, similar to those experienced in both the 1906 San Andreas and the 1989 Loma Prieta events in California.

In Summary

The purchase of a home, whether it’s a conventional build or a prefab home in Spain, is usually the largest single investment a person will ever make. Because of this, structural and non-structural problems that occur during the life of a house can be both financially and emotionally draining. In the Mediterranean region, where earthquakes are more frequent and violent than anywhere else in the European Union, the prudent homeowner will take all necessary precautions to protect their home against any loss. Buying a steel framed prefab home built by Casas Mundiales is a reliable way to protect your biggest investment.
