Rastra® panels are
large building blocks with a grid of internal channels allowing panels
to be used horizontally or vertically. Once the
Rastra® panels are
joined together to form a story-high wall they are filled with
concrete. The cells in each element then form a continuous
structural grid, which gives
Rastra® its high
strength. Variation of the concrete formulation and amount of
reinforcement allows
Rastra's® load
bearing capacity to be adapted to almost any application.
Rastra® walls serve
as a fire and thermal barrier.
