When selecting corrugated iron as a building material, it's important to consider the disadvantages it brings, despite its many benefits. Corrosion, thermal properties, noise, environmental factors, and more are all part of the drawbacks to using corrugated iron. In this comprehensive overview, we'll delve into the specifics of each negative aspect of the material and what you should keep in mind when deciding if it's the right choice for your project.
1. Corrosion:
The downside of using corrugated iron is its tendency to corrode. Despite being galvanized to prevent rust and corrosion, the zinc coating can break down over time, making the iron more susceptible to rusting. This is especially concerning in areas with high levels of humidity, exposure to harmful chemicals, or proximity to the coast. To prevent it from happening, regular maintenance and protective coatings are necessary. By doing so, you can avoid the potential drawbacks of using corrugated iron and extend the lifespan of the material.
2. Thermal Conductivity:
Corrugated iron roofs have a relatively high thermal conductivity, allowing them to quickly transfer heat. This characteristic can be problematic in regions with hot climates as the roofs absorb and radiate heat, resulting in uncomfortably warm interiors. Conversely, in cold climates, the roofs can draw heat away from the indoor spaces, making them chilly. As a solution to combat these issues, insulation is often necessary, adding to the overall construction expenses.
3. Noise:
Corrugated iron roofs can produce an excessive amount of noise due to precipitation like rainfall and hail. As a result, quiet places such as residential areas, schools, and offices may not be suitable for such roofs. To mitigate the disruptive noise levels, it becomes imperative to consider acoustic insulation options. This would help in reducing the noise and creating a more sound-sensitive environment.
4. Expansion and Contraction:
The use of corrugated iron sheets in roofing systems is popular due to their durability and cost-effectiveness. However, it's important to keep in mind that temperature changes can cause these sheets to expand and contract. This movement can have negative consequences such as the loosening of fasteners and the development of leaks. To prevent these issues, it's essential to use proper installation techniques such as allowing for expansion joints. These joints will give the sheets the necessary space to move with temperature changes and will help maintain the integrity of the roofing system.
5. Aesthetic Considerations:
While corrugated iron may appeal to some people due to its industrial or rustic look, others may find it unappealing or unfitting for certain architectural styles. The functional design of corrugated iron may not be appropriate for upscale residential or commercial projects where a more refined look is desired.
6. Limited Design Flexibility:
