ICF Home Construction

ICF (also known as insulated concrete forms) are made from expanded polystyrene.  At Kleinschmidt Construction we prefer to use Logix brand ICFs. 

 There are many different types of blocks from Logix that allow us to meet our clients needs. 

   This is a standard Logix form.


ICFs can be used for foundations and walls.

There is no limit to the height of your walls or the number of stories

Logix interval widths are 4 to 10 inches and each block has 2.75 inches of foam. 

Other brands use 1.5 to 2.5 inches of foam.

Thicker foam:

  • Helps prevent damage from handling
  • Prevents distortion when pouring concrete
  • Allows walls to be straighter and flatter

 There are many benefits of Logix which include:

  • Highly energy efficient
  • Blocks twice as much outside noise
  • Reduces areas for mold and mildew growth
  • Ensures dry basement with waterproof system
  • 8.5 times stronger than wood framed wall
  • Withstand harsher weather conditions
  • Cold weather construction
  • 6 1/4" block has 3-hour fire resistance rating compared to 15 min. for wood framed wall


This picture shows an ICF home during construction in Wisconsin that went through and F3 tornado a couple of years ago.  The debris around it are from the other homes around that were completely destroyed.  Which home would you want to be yours?


 Here is a comparison of Logix to stick-frame

Stick-frame home

These pictures were taken of homes on the same street at the same time.  It is very easy to see the large amount of heat loss from the stick-frame home. 


Logix is environment friendly

  • Built to last for centuries
  • Conserves forest resources
  • Made from recycled plastic
  • Reduces fuel consumption

 Common questions we hear:

  • Is it hard to remodel an ICF home?

With new diamond blade saws and other technology it is very possible to remodel an ICF home. 

  • How do you apply interior and exterior finishes?

Logix blocks have strips of plastic that run up and down the block.  These are every 4 inches and material can be fastened directly to these strips.  This allows any type of material to be applied such as sheetrock, steel siding, or wiring for preparation of stucco. 

  • How do you support brick on the exterior?

Logix has a corbel block (pictured below) that curves out and allows brick to be placed on this ledge. 


  • What are the cost differences?

 The building cost per home is about 5% higher than stick-frame homes.  But in the long run it will pay for itself because of the efficiency of the blocks and increase of security and comfort you will have in your home. 

Take a look around some of our job pages to get a visual on how ICFs are used during the construction process.  You will also notice that the final product does not look any different than a convential home and you would not be able to tell from the street which homes were built with ICFs.  Another thing to keep in mind is that ICF construction is not limited to residential construciton.  We have also used ICFs when building commercial projects.
