has been used in all environments
from the Austrian Alps to the Saudi Arabian Desert, to the humid climate
of Southeast Asia for more than 30 years.
offers the ultimate in properties for a wall, such as insulation,
soundproofing, fire protection, all in one easy-to-install element.
also is resistant against frost and heat radiation. It does not
entertain mold or attract nesting insects. 85% of its volume
is recycled post-consumer polystyrene waste which very likely
would have ended up in landfills never to disappear.
into the cavities of the elements provides excellent strength. The
channels inside the elements have been designed to provide optimum
strength while using the lowest possible amount of concrete. The square
grid allows use of the elements either vertically or horizontally,
maintaining the grid and the runways for reinforcement. By using
different strengths of concrete and various amounts of reinforcement,
the load capacity can be adapted to any requirement.

element has an area of 12.5 sq ft and is generally used for walls;
element is used for ending wall-sections, members of headers,
sills and corners. Rastra®
elements can be easily cut, rasped, routed or even carved into
sculpture-like forms, using common tools for working with wood.
Plaster adheres well to the face of Rastra® elements without any preparation, tiles can be glued right onto
The Rastra® elements are produced in state-of-the-art facilities. All plants
are highly automated and the process is computer controlled.
Strict quality control is maintained and continuously monitored
as well as audited by independent laboratories.
Rastra® elements are molded in a special process. The spongy raw material
used to make ThastyronTM
is compacted by applying a certain amount of pressure before
elements are set upon a pallet for curing.
The Rastra® elements are cut to exact dimension after they have been cured.
This guarantees small tolerances and straight and even walls.
Even the production process is designed to protect our environment.
As no energy is used to cure the elements, on average less than
2kWh is needed to produce each Rastra® element. During production, no byproducts are set free which
may be considered a burden for the environment. All debris from
trimming the elements is immediately recycled and made into new
