Publication number: 20130316134Abstract: An insulated wall panel comprising of two outer layers, an insulating foam core, and a spacer within the foam core which holds the panel spacing and retains the foam during foam introduction and expansion in the cavity and remains as part of the panel. The panel has no thermal bridging between the outer layers and is manufactured with reduced need of rigid mold forms. The final effect after pouring becomes a monolithic foam core of substantially consistent material and provides a superior product to using dissimilar retained spacing materials.Type: ApplicationFiled: May 25, 2012Publication date: November 28, 2013Applicant: Earthcore Worldwide, Inc.Inventors: Scott C.
