Cast earth-cellulose form system
Characteristics:
Composed from agricultural cellulose and minerals, this material may have potential as a strong and resistant product
for use in building construction, with production at either cottage industry or mass production levels using local
materials and labour.
Interior or exterior surfaces can be moulded to have functional and decorative features.
Oriented strands of cellulose fibres increase strength.
Density of the material can be manipulated.
Some products are suitable to be made or applied with portable equipment, while others would be extruded or moulded into shape as baseboards, trim, doors and jambs, or structural profiles
Properties:
Unconfined compressive strength 350 psi

Density: 800 kg/cubic Meter approximately. Various densities available.
Fire rating not tested. Sound Transmission not tested. Heat conductance not tested. Similar materials have no flame spread and excellent sound damping functions, with moderately successful R values, according to German tests of light clay traditional building material.
