Concrete construction, on the other hand, is made of sand, gravel, and cement which is a mineral product. Besides saving trees, insulated concrete form (ICF) construction, in which concrete is poured into stacked foam blocks, generates scarcely any waste. But the difference between ICF vs wood construction is not just a matter of saving trees. ICF is easier and faster to erect than wood framing, it is stronger and more durable, it is more fire resistant and it is cheaper – much cheaper – to heat in the winter and cool in the summer. arti mimpi
ICF construction means a virtually sealed thermal envelope, so there is practically no leakage of heat; moreover, as compared to wood, concrete has a thermal mass which absorbs and radiates heat in the winter months, and is cool and cooling in the summer. So not only do ICF homes save trees in their initial construction, but also they consume substantially less energy over the life of the building. This means reduced dependence on fossil fuels, which means less of the carbon dioxide emissions which contribute to climatic change, and less of the sulfur dioxide emissions which contribute to acid rain and air pollution. Today’s home buyers are more aware of the impact of their decisions than home buyers in the past. They are more interested in recyclable materials, energy efficiency, daylighting strategies, and indoor air quality than they are in impressing other people with overblown homes. More and more people are turning to NUDURA ICF blocks to build their homes, both to save trees and to help the environment.
