The history of Insulating Concrete Forms in low rise buildings is long and storied, but ICF is being designated for mid-rise and high-rise buildings over 100 feet and higher, every day. Join us today, as we bring you tips for building walls higher, better, and straighter with ICF.
Plan Out Your Work
Decide on your approach ahead of time by drawing a simple cross section with your ICF. Holes are placed in the areas where the ICF joint and the insert are placed.
Consider your ICF formwork‘s altitude. When designing walls, designers can (and should) consider the physical height of ICF products to significantly reduce the amount of formwork cuts they make. Professionals confirm you should consider the height of the wall whenever possible.
Consider STC ratings for your operation. Once you’ve found the sound transfer class, consider what you’ll add to your ICF wall if your STC rating is 50 or higher.
Fill In With Concrete
Make sure that your forms are completely filled in with concrete. Place a single stiffener in the center of the wall to allow more room on one side of the stiffener, then fill in carefully with concrete. Assign larger reinforcement intervals than required for better results.
Consider self-reinforced concrete to help take some of the guesswork out of your project. Self-assembled concrete increases the pressure on your forms, meaning ICF systems may require additional bracing.
Repeat Your Window Pattern
Where possible, always repeat your window patterns. Repeat the floor-to-floor window pattern for multi-stage applications such as multi-generations, luxury living and hotel projects to build up a gap to fit the full height of the wall assembly. This will maximize the efficiency of both your design and construction.
Don’t Forget The Insides
The higher your wall, the harder and more expensive it becomes to cover the exterior of the wall. Proper bracing ensures walls will be straight and level. This can affect other sub-transactions, wall closures and the building’s structural integrity.
