ICF Exterior Wall Finishing

Can you apply any siding to insulated concrete forms? This is a frequently asked question in the industry. It’s an understandable one, given that on the surface, EPS foam panels and ICF block construction may not sound all that conducive to traditional exterior finishes. But that’s just one of the myths surrounding insulated concrete forms. It’s a big part of why as a NUDURA supplier, we offer training programs for builders and contractors looking to better understand ICF applications. That being said, we’re here to answer your query about ICF and exterior finishes today, so let’s get to it.

3 Things You Need to Know About Finishing the Exterior Walls of Your ICF Build

You Can Do (and Install) it All

There are essentially no limits when it comes to the exterior finishing of your ICF build. If you can add it to a traditional wood frame building, you can add it to an ICF-constructed one. More often than not, it’s even more effective given the strength and durability of the building blocks. Think about it. Which instills more confidence if you’re looking to apply a natural stone or brick finish to the outside walls of a new home – a wooden skeleton or concrete blocks? ICF buildings can accept all types of siding, including:

  • Brick
  • Natural Stone
  • Synthetic Stone
  • Stucco
  • Vinyl Siding
  • Wood Siding
  • Hybrid Combinations

Since you can install any of the above siding, you can achieve any aesthetic and design that a residential or commercial client is interested in, including:

  • Heritage
  • Colonial
  • Cape Cod
  • Cottage
  • Art Deco
  • Contemporary
  • Mid-Century Modern
  • Mediterranean
  • Neo-Classical
  • Prairie
  • Ranch
  • Victorian

Thanks to the above, not only are building contractors excited about ICF, architects and designers are too.

What About Unique Exterior Features and Shapes?

You now know that ICF can accommodate any type of siding that you have in mind. But what if a property is more unique, with curved sections and other distinct exterior features? Not a problem. In addition to NUDURA’s (supplied in Alberta by Total ICF) factory custom cut radius forms, including 45° and 90° forms, there is a diverse selection of NUDURA component blocks. With these blocks, you can design curves and accommodate unique exterior features and therefore apply any form of wrap-around stone (or composite) siding. Look no further for proof, than these unexpected ICF applications, which include a pool grotto with a barrel-vaulted roof.

Window and Door Trim Too

Beautiful window and door trim is essential to completing the aesthetic of a build. Concerned about the likes of arches or bay windows? Don’t be. Any exterior window or door style can married into the design of your ICF build. With our NUDURA products, no additional specialization is required. Your architect/designer will not need to specify custom products or materials.
