Environmentally Friendly Construction Materials

The use of environment-friendly construction materials is becoming more popular these days. Partly, because of the louder calls for sustainable living; and largely, because of the immediate need to improve earth’s health. The acceleration of environmental problems such as resource depletion and climate change has strong association with the real estate industry – specifically with new construction.

If you are buying a new home, you could already be thinking of purchasing one that is more conscious of the environment. Here are some of the construction materials that befriend nature, deserving your attention of probable choices for the house you are going to buy.

Lime

This material has been used in buildings since the ancient times probably dating back to some 5000 years ago. Evidences point to its usage because of its resilient, durable, and water resistant properties. Contrary to modern coatings, lime in its original state which is calcium carbonate, has the ability to release the moisture from the surfaces – rather than trap it. This material has been rediscovered by construction engineers and applied today as one of the eco-friendly materials in green home sand buildings.

Cob or Mud

Have you ever read history books with sections dealing with houses made of mud or clay? These houses are called cob homes. Many of them are located in Asia and in some parts of Africa and Europe. Cob made use of clay-based soil, water and straw – mixing them together until desired thickness and ladling them into the stone foundation trodding them into place. Modern construction got inspiration from this and basically employs the same materials and principles. But with the use of mud loaves, the cob can get thicker to up to 300 to 500 mm. Rubble trenches, earth bags, and rammed tyres can be used as cheap foundations.

Flax and hemp

These materials are eyed as natural alternatives to expensive insulation materials like fiberglass, mineral wool, and multi-foils. Flax and hemp are natural plant fibers which are made available to the construction industry in batts and rolls. These plant fibers contain borates which have fungi and pest-killing properties along with its fire-retardant capabilities. To bind them together, starch is added. The eco-friendly property of these materials relies on their low embodied energy.

These are just some of the environment-friendly materials which you may want to consider for use on your new construction house. For other eco-friendly construction materials, you can talk to your local real estate agent who has the freshest information about green building and green real estate.
