You should build your gable walls with Logix ICFs if the gable section is heated or the gable walls require high wind resistance.
ICFs make a suitable building material for gable walls that enclose a heated section of the home. For example, a high vaulted ceiling in a great room is bound to accumulate rising heat, so blocking heat transfer with highly efficient ICFs is an excellent idea.
On the other hand, if the gable walls enclose an unheated attic, framing can suffice — there’s no need for the additional energy efficiency ICFs provide.
Likewise, ICF gable walls can provide much-needed lateral resistance in regions with strong winds. That’s because ICFs excel at withstanding high wind loads thanks to their reinforced concrete cores.
However, if high wind resistance isn’t a must, a simple gable end truss detail will do just fine.
How to Build Gable Walls With ICFs
There are two primary methods for building gable walls with ICFs:
- Assemble the walls on the ground and hoist up. Most builders prefer this option as it’s generally the most straightforward.
- Build the gable section in place. This option works best on smaller sites with tight access.
Below are a few tips to help you build ICF gable walls.
- Use screws to attach 1×4 strips along the diagonal cuts you’ve made to the ICFs at the top of the gable section.
- Attach plywood to the 1x4s to help contain the concrete during and after the pour. Or, you can use zip ties to help restrict the concrete flow during the pour.
- Trowel from the bottom up after the pour.
- Use scaffolding to brace the ICF gable walls. However, if you do so, make sure the staging is adequately braced to the floor system.
- Have the roof attachment hardware ready, as it must be installed during the concrete pour or immediately after it.
Wrapping It Up
Using Logix ICFs to construct gable walls makes sense when the gables enclose a heated space or have to withstand significant wind loads.
If you choose to build your gable walls with Logix ICFs, we hope our tips above help you make the installation quick and straightforward.
Are Logix ICFs Produced in Company-Owned Plants? And, Why Does It Matter?
When you order Logix ICFs from your local dealer, you’re getting blocks that were produced in a plant that is an owner of the Logix ICF brand.
As such, when you order Logix ICFs, you should count on great service, fewer delays, shorter lead times and a consistently high level of quality.

If you’re ever faced with uncommon wall angles, following the 9 simple steps above will help you field-cut your ICFs in as short a time as possible and with little waste.
Climate Resiliency: A Guide to Climate-Resilient Structures
To adapt to climate change and adverse weather events, we need to use climate resiliency strategies in construction. Climate resiliency methods can both contribute to slowing the pace of climate change and make our buildings more resilient and less susceptible to damage.
