ICF wall systems have been used for building applications ranging
from single story buildings to 20+-story high-rise buildings and everything in between. There are examples of ICF buildings all over the U.S.
and Canada, including single-family residential, multifamily residential,
hotels, dormitories, assisted living facilities, offices, healthcare facilities,
manufacturing and warehouse buildings. Schools built with ICFs are
popular due to low- or net-zero energy use. Theaters are also trending
toward ICF construction for superior sound attenuation. For this article,
we'll focus on multifamily occupancies, including apartments, condos,
hotels, dormitories and assisted living facilities.
What makes ICFs so attractive for multifamily construction is that they
are cost competitive with wood frame, steel frame and masonry construction. A building owner gets a building that is more disaster resilient and
energy efficient at or nearly the same cost. Fire safety is a key element of
multifamily construction since occupants sleep in these buildings and
are often challenged to evacuate during a fire. Concrete walls and floors
provide the fire resistance needed to not only allow occupants to evacuate,
but contain the fire within a single unit, imposing less risk on fire fighters
and property.

ICF Concrete Wall Systems
Typically, ICF wall units are comprised of large molded EPS blocks,
similar to Lego® blocks. Each individual block is manufactured in an EPS
manufacturing facility. The blocks range in size from 48 to 96 inches
long and 12 to 24 inches high depending on the manufacturer. The most
common configuration of an ICF unit is made of two layers of 2-1/2 to
2-5/8 inch thick EPS spaced 4, 6, 8, 10 or 12 inches apart depending on
design requirements. The most common spacing is 6 inches or 8 inches
for most low to mid-rise buildings, but for taller buildings, taller walls or
exceptionally large loadings, thicker walls are necessary. For simplicity,
ICFs are generally called out by the width of cavity, hence an ICF with a
6-inch cavity is called a 6-inch ICF and an ICF with an 8-inch cavity is
called an 8-inch ICF and so forth.
The blocks are designed to have interlocking teeth that hold the forms
together much like Legos®. Most manufacturers not only supply straight
blocks but have corner blocks, angled blocks, t-blocks and some even have
curved blocks. Most even provide special blocks with brick ledges. Most
companies supply blocks that are fully assembled and ready for installation, but some ship blocks that are folded into a flat configuration and
then unfolded for installation. One manufacturer ships blocks and ties
separately that are assembled on site. Many have special window and door
bucks along with other accessories such as bracing, clamps and scaffolding
to make the construction process more efficient.
There are some ICF forming systems that are made of other insulating materials and with slightly different configurations and shapes, but
