Fire Resistance

Insulating concrete forms resist fires in several ways. The most obvious is their
structural concrete core that will not weaken, warp. twist , or burn regardless of the
fire’s heat. In so-called “fire-wall” tests. ICF walls withstood temperatures of up to
1000°C for as long as 4 hours without any sign of weakening .
Ensign Flexibility
is   already noted, insulated concrete form construction can be adapted to virtually any
residential or commercial project.
adapting an architectural flourishes are actually easier with ICF. For stance radius walls,
which are difficult to build with frame or block construction, are simple.
long clear spans can be easily accommodated, because the walls In carry the loads and
steel beams these designs require. windows can be made larger in seismic zones.
while ICF walls look dramatically different from plywood-sheathed fame construction,
they’re actually easier to work with for most e xterior finishes.
the foam substrate is perfect for cement-based stucco or textured acrylic finishes.
Brick, stone, and manufactured stone are also applied more easily to ICFs than frame,
as n o additional vapour barrier is d eeded.
Contrary to popular belief, the foam used in ICFs will not burn. It will melt if exposed
to high heat, but it will not contribute any fuel to the fire. In fact, it is virtually “self-
extinguishing,” thanks to a flame retardant all of the leading ICF manufacturers add to
the EPS foam.
