Insulated Concrete Forms (ICF)

Groen Construction Inc. NH premier ICF Contractor and ICF Installer.

What is ICF?

Why should you consider it?

Insulated Concrete Forms (ICF) is a foam forming system for concrete.

The two sided blocks are stacked like legos, reinforced with rebar and then pumped full of concrete. Unlike conventional concrete forms, the ICF’s stay in place, sandwiching the concrete in between two layers of foam.


ICF is a versatile wall assembly, offering varying core thicknesses and rebar layouts to accommodate specific structural requirements.


Essentially any interior finish or exterior siding applications that you’d use on a wood framed wall can also be attached to an ICF wall. In most cases, drywall is attached directly to the interior face of the ICF wall and the siding application of choice is attached directly to the exterior face.


While ICF has been around since the mid 1900’s, it’s not until recently that it has started to gain widespread use in both residential and commercial construction.  In its earlier years, ICF was used mostly for foundations but over the past couple of decades, ICF has become a preferred choice to many for both below and above grade walls.
