Introduction

dormitories, assisted living facilities, offices, healthcare facilities,
manufacturing and warehouse buildings. Schools built with ICF
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 commercial applications, including offices, schools, retail and institutional buildings. To learn
more about ICFs for multifamily residential, including apartments, condos, hotels, dormitories and assisted living facilities visit

ICF Wall Systems
The efficient construction process is what sets ICF building systems
apart from other building systems such as wood frame, steel frame and
masonry construction. ICF construction can help contain construction
costs and reduce construction time because of the inherent efficiencies
of the installed assembly that serves nine functions:
1. Concrete form (that stays in place)
2. Thermal barrier
3. Air barrier
4. Moisture barrier
5. Fire barrier
6. Sound barrier
7. Substrate for running utilities

Insulating Concrete Forms, or ICFs for short, combine two wellestablished building products, reinforced concrete for strength and
durability and expanded polystyrene (EPS) insulation for energy
efficiency. ICF walls are made up of two layers of rigid insulation
held together with plastic ties to form ICF units with a cavity in the
center. The ICF units are stacked in the shape of the wall, reinforcing
steel is added into the form cavity and then concrete is placed into the
form. The result is a reinforced concrete wall with a layer of insulation
on each side. What makes ICFs different than traditional concrete
construction is that the forms remain in place after the concrete is
cured to provide thermal insulation. The combination of reinforced
concrete and insulation provides an ideal load bearing wall, thermal
envelope, fire barrier and sound barrier.
Most buildings built in North America are low- to mid-rise buildings using bearing wall construction. This means there are exterior and
interior walls that are designed to carry the vertical loads and the floors
span between the bearing walls. Often the bearing walls also serve
to resist lateral loads from wind and earthquakes. ICF wall systems
have been used for bearing wall buildings ranging from single story
to high-rise buildings up to 30 stories tall and everything in between.
There are examples of ICF buildings all over the U.S. and Canada,
including single-family residential, multifamily residential, hotels,
