Chapter 4: Expandable Container House vs Other Traditional Building Materials

  1. Expandable Container House  vs Woods Building Materials
  • Cost Criterion: Woods can be a little cheaper than steel in terms of purchase. However, steel longevity in terms of years is better off compared to woods while the expandable container house is also affordable and suitable for economic residence.

There is still another criterion to consider.

  • Shrinkage and Swelling Criterion: Woods is a hygroscopic material. This makes it susceptible to shrinkage and swelling because it absorbs condensable vapors. On the other hand, the expandable container house does not absorb condensable vapor. It does not shrink or swell. For this reason, the expandable container house is better than the woods.
  • Perishability: Woods is more perishable than steels. This is because it has more detriments. The detriments that cause the destruction of woods to fall into two categories which are biotic (biological) and abiotic (non-biological).

Do you know that woods are organic foods? They are foods for some organisms. This makes them destructible by fungi, termites, carpenter ants, powder post beetles, bacteria and insects. All this makes the wood to destroy and threaten its longevity.

On the other hand, expandable container house is made from galvanized steel and this product are not edible to any biological barriers. This makes expandable container house lasts longer than woods.

Although, woods can be prevented from the biological barriers. This requires occupants to spend excessively on treating woods with preservatives. With the use of the expandable container house, you need not incur all these excessive preservative costs.

Do you know?

Woods are very vulnerable to abiotic barriers like fire. It easily catches fire and may lead to huge loss of life and properties. With the use of an expandable container house made of steel, the risk of losing life and properties to fire outbreak is very limited. This is because steel is not vulnerable to fire accidents.

There is more to learn.

  • Avoidance of Insects and Bugs Criterion: One of the terrors that disturb people in their various residence is bugs and other kinds of insects. With the use of woods, the insects have the tendency to be on the increase. This is because they feed on the woods too. But with the use of expandable container house, bugs and other insects are on the decrease or not at all. This is because it is not conducive for them to prosper.
  • Water Resistance: One of the things to consider is the material that offers more resistance to water. Woods offer less resistance to water because it gets weakened by water invasion. Steel, on the other hand, has the tendency to get rust to water invasion. But at Sunnyda building company, steel has been pre-painted with good paints that remain permanent even under heavy rain and waterfalls.
  1. Expandable Container House vs Bricks and Cement
  • Cost Criterion: It is more expensive to have a building of traditional materials than to have a construction of prepainted galvanized steel.
  • Time Management Criterion: While it may take a very long time to build using sand, bricks, and stones, the construction of a standard structure of expandable container house only takes an average of 2 hours.
  • Mobility Criterion: For your traditional building, one there is a necessity to relocate to another location, the building remains fixed and another building cost is used again. However, in the case of expandable container house, you only have to deconstruct your structures and accessories and reconstruct on the new location without spending new building cost.
  • Recyclability Criterion: Whereas any attempt to recycle traditional building materials will only result in sand and dust that will pollute the environment, with an expandable container house, it is not so. Expandable container house can be recycled and reused for other purposes other than building.

Having seen that expandable container house has some benefit that makes it above other building materials, there are other things to consider.
