Learn more Logix XP-1 XP-1 is a self-aligning complete solution for ICF walls with exposed concrete. Rising acceptance of insulated concrete forms in temperate regions including Europe and North America on account of their superior thermal insulation properties. Learn more Logix KD These unassembled knockdown forms ship flat to minimize freight costs. Department of Housing and Urban DevelopmentOffice of Policy Development and ResearchWashington, DC Portland Cement AssociationSkokie, IL by NAHB Research Center, Inc.
