One main reason why ICF has become popular among builders is that there is virtually no learning curve. While we don’t want to give the impression that any homeowner can sign up for a Nudura one-day training course and become an expert with the system, professional contractors should generally understand how to install the systems after taking our training course. We take pride in the hands-on work we do with distributors and Nudura-trained installers to successfully manage any job from start to finish.
We find there is a common misconception about the complexity of inserting steel rods into the monolithic cavity. With an understanding of straight, plumb and level, however, it’s pretty simple. Once the forms are linked together, horizontal steel rods are set into the hollow cavity to provide the strength for the wall. After the forms are stacked to their final height, vertical steel is inserted at regular intervals and concrete is poured in from the top of the wall using a concrete boom pump.
Drywall is very easily attached to our EPS foam using standard coarse head #6 drywall screws – the same way they would be attached to stud wall in a framed wall construction. Each of the ties that cross across the cavity are fitted with a 1.5-inch wide fastening flange. The screws can be mounted directly into the flanges, which have been tested to ensure the screw does not pull out of web fastening strips in the foam. On the outside face of the foam, Nudura forms feature a diamond pattern that clearly indicates where screws are applied to anchor into the wall itself.
