What material are homes in Iceland made out of?

Homes in Iceland are primarily built using concrete and corrugated metal sheathing. Concrete is one of the most popular building materials due to its durability, energy efficiency, and resistance to harsh weather conditions. Corrugated metal sheathing is commonly used for external walls and roofs due to its flexibility, long lifespan, and weather-resistant properties. Additionally, modern Icelandic homes often incorporate renewable energy technologies such as geothermal heating and solar panels for sustainability.
