Cob - A Natural Alternative

Introduction According to the article by Cob - A Natural Alternative (Anderson, 2009), cob is a natural material that has been made for centuries for centuries. Cob's house is still standing today. The building of the cob is cheap and gentle to the earth. The spindle building uses a simple mixture of clay, sand, and straw fibers to create a durable structure. It is world famous. In America, maize cobs replaced trees to build a house. People want to find the natural materials they use, so people are interested in corn cobs.

Insulation is used for roofs, walls and floors. An alternative way to use the cob and adobe's solid wall structure is not insulated and Cob and Adobe offer excellent thermal mass to compensate. A house built with crates requires insulation of the wall in the form of a roll or plate, the bat (the preformed part is designed to fit between the walls), roll or plate. Other types of construction methods such as brick and concrete are insulated with spray foam, rose filler or roll. The insulation works by resisting the heat flow and is measured by the R value (the higher the R value, the greater the thermal insulation). R value varies depending on material type, density and thickness, and is affected by undesirable heat flow generated in thermal bridges, beams, studs and trusses. Sustainablebuild.co.uk (2010)

Because of the time and labor, contractors do not like to use Cob material. It makes the needs of the community visible, and shows our unanimous power agreement. The cob needs to "breathe" - After getting wet it will dry naturally. In the past, the outer wall was left with naked or lime (these days are expensive). Too much moisture can cause problems (3-5% is considered good - if it exceeds this level it may raise humidity). The spindle usually exceeds the minimum U value of the house

The house is typical of the frame house of the Portland 1900s, except that she added green roof and corncob sauna. Cob is a building technology of DIY that uses thick clay and straw to make thick walls without using many trees. She transformed the cellar into an office with a concrete floor and a projection room that felt like an art bunker. The way she hugged and reworked her old house reminded her of her work. Both are tense between old and new, and we finally clarify where she works hard.
