American PolySteel is the first
insulating concrete wall system to pass the rigors of a four-hour
fire test without the addition of any wall
coverings
required to assist in its performance. More
about this.
PolySteel's unique steel ties
hold the EPS foam together, further insulating the walls
and providing added protection on the side unexposed to
the flame.
PolySteel's extremely low toxicity,
smoke development, and flame spread, make
our walls safer from the hazards of fire.
The air tightness of PolySteel
structures also inhibits the oxygen needed to allow a
fire to spread rapidly.
