New Ideas in Building

John Deterding Company is enthusiastic about Rastra, a sustainable, energy efficient, environmentally correct construction system he used in the Rumsey band community.

85 percent of Rastra’s volume is made of recycled post-consumer polystyrene wastes that very likely would have been left in landfills for an eternity.

Rastra offers the structural strength of concrete paired with high thermal insulation, sound attenuation and fire-resistance. It can be used for every type of wall and other components of a building while being resistant against frost, heat radiation, mold and nesting insects.

Rastra can be easily cut, rasped, routed or even carved into sculpture-like forms. Plaster easily adheres to its surface, and tiles can be glued right without any preparation.
