Estimating Residential ARXX ICF Projects

Due to the acquisition of ARXX by Fox Blocks and Airlite Plastics, the ARXX estimating program wil no longer be supported and is replaced by the Estimator PRO4.

To help determine your residential project cost, please start by selecting one of the material estimating options below. When your material estimate is complete, an ARXX Representative will be in touch to connect you to your local distributor who will provide you with a quote and recommend a trained ARXX Installer or ARXX Trainer in your area.

For commercial project estimates and projects outside of the United States and Canada, please contact Fox Blocks at 877.369.2562 or email
