Book excerpt: Building with straw bales is being embraced by amateurs and professionals for its versatility, comfort, environmental friendliness and high insulation. New methods should expand its growing worldwide popularity. In Practical Straw Bale Building, Murray Hollis uses simple, easy to understand language to describe the established techniques of straw bale construction and ways in which they can be improved. He also presents a new straw bale construction system that has substantial benefits over current methods. This system incorporates a new tensioning system that replaces the use of fence strainers for tensioning the hold-down/compression wires and eliminates uneven tensioning on opposite sides of the wall. It also allows for fabricating wall modules on-site as horizontal modules that are then swung into the vertical wall position after fabrication. Aspects of structures other than walls are addressed only to the extent that they are relevant to the use of straw bales, e.g. issues such as types of floors, roof structures and methods of heating or cooling. The innovative methods in this book will help to progress straw bale building technology and move it into the mainstream of the building industry.
