Reward Wall Systems’ Boost-R Panel can increase insulating concrete form wall R-values to R-30 and up to R-55 for specialty applications. The panels are designed to slide over eight form ties and rebar chains and snap into place. Because the panels are placed inside of the ICF core, the furring strips are still accessible for attachment on the outside of the form. They allow for different types of foam, foam densities and thicknesses of the panels to meet R-value requirements.
