We cannot fail to mention the behaviour
of Glued Plywood towards fire, above
all in the structures CARAMES offers,
which reach a huge resistance. This
fact, known since long ago, comes
from a property wood has versus
other building materials; the coal
formed at its external layer when
burning prevents the passage of
oxygen into the wooden piece, restraining
combustion.
CARAMES Glued Plywood structures
are highly resistant to fire,
a feature that expands the thicker
the pieces are, causing an average
0.7 mm/min advance of fire, quite
the reverse from what occurs with
other materials which easily transmit
heat causing changes and deformities
that rapidly damage the structures.
After many studies that have
been conducted, we could assert
that wood behaves better towards
fire than concrete, steel or aluminium.
These lose resistance and rigidity
with heat, rapidly deteriorating,
whilst it takes wood, a bad heat
conductor, much longer to heat
up and, in turn, when it dehydrates,
its resistance to compression
and flexion increases, ensuring
the structures' stability for
a long time.
