HOW TO MAKE WALL PARTITIONS
WITH "LIGHT STRAW-CLAY" (COB)


Here's an inexpensive alternative to the usual way wall partitions are built. Instead of framing up, then insulating with fiberglass and covering with sheetrock, the wall cavities are filled with a mixture of straw and clay (known as "cob"). The wall is formed up in sections.

INEXPENSIVE MATERIALS USED:

- 2"x4"s scrounged from dumpsters at new house construction sites
- Pre-owned doors from a demolition company (total cost for three doors including the hardware was $20 and these were solid-core doors)
- Chopped Straw
- High-clay content soil

PROCEDURES FOR CONSTRUCTION OF THE WALLS:


In the case of the wall in our new straw bale house, one side of the wall was
stuccoed with lime plaster to seal cracks and increase sound proofing...

The other side was left natural with the raw cob exposed
and then sprayed with a mixture of pure clay and water ("clay slip")

Here's the finished wall...


NOTE: COB has been used for many centuries to build houses, such as this house in Devon, England with a traditional thatched roof.

 

There are many excellent sites of the Internet which cover this subject in great detail. See Cob Cottage, for example. As these houses are basically hand scuplpted, they can be made in the most beautiful and creative ways immaginable...
