Corrugated Iron Cladding
In New Zealand we all know corrugated iron as the roofing material, but as a cladding option? The fast installation time as well as light weight and the ease of fixing any leaks have meant corrugated iron manufacturers started to expand their product portfolio and get into cladding. Here we look at the pros and cons of the material as well as environmental considerations.
Corrugated iron has proven itself as a roofing material that is affordable, easy to install and easy to fix. The light weight will certainly also as a cladding keep foundation costs to a minimum. Similar to all metal claddings, corrugated iron does conduct heat. Everyone having a corrugated garage knows they overheat inside in summer as the sun heats up the metal and the metal conducts it inside the garage. So be careful children, it might get hot to touch. Metals do conduct heat easily; losing more heat through the envelope than other cladding materials.
Advantages of Corrugated Iron:
Lightweight cladding material
It is recyclable, though mostly recycled in China and not NZ
It is easy and fast to install as it comes in larger sheets, cutting down on installation costs
Disadvantages of Corrugated Iron:
Potential of rust
Corrugated iron is often treated with chemicals and paint to avoid rust, algae, and mildew. The chemicals are often toxic and bad for the environment
While the recycling of metal is possible we are currently unaware of any manufacturer offering recycled iron in NZ
