What Are Some Natural Materials For Green Built Homes?

Green Built HomesThere are several techniques for green built homes, but what are some of the most often used natural materials? Here we will look at several materials that allow you to create a sustainable green built home that minimizes the ecological impact and footprint. These are non-industrial, locally available, minimally processed and renewable materials that utilize materials that are either recycled or they are salvaged.

Of course, these materials can vary based on the local climate and bioregion because those factors into what materials are appropriate just as the technique used with the materials are. Depending on the climate where the home is being built, a combination of the following products may be used for creating green built homes: 

Cob – By combining clay, sand and straw we create cob, which is very much like adobe. The difference in this type of green built home is that bulges of cob are placed on while wet, building a bench or wall. It is akin to creating a sculpture.

Earth Bag – By mixing gravel or sand and then hardened the mixture with clay will allows you to pack it into burlap feed bags or polypropylene bags. Then stack the bags create a wall. And then plaster the walls as a layer of protection for the bags. This allows you to sinuous wall shapes. The burlap bag is more of a green built product but not has easily obtained. The polypropylene bags are a replacement product, but not as durable for green built homes.

Light-Clay Straw – This is also known as slip straw which is mixed with clay and water. When mixed to the proper consistency similar to paint, it then mixed together with loose straw so that each fiber of straw is coated. It is then formed and put into wall cavities providing a green built insulation. After the mixture has dried, it can then be plastered using plaster made of earth materials or lime plaster.

Straw Bale – Straw bales are used somewhat like bricks by stacking them to build walls. There are load-bearing bales that support the roof and non-load bearing straw bales.
