Enercept panels are manufactured indoors and delivered directly to job sites for construction. The floor system must be level and square before attaching the sill plate and erecting the numbered wall panels using an approved sealant. Window panels consist of a lower panel and upper lintel that are caulked together before sliding the upper panel into place and nailing it securely. Gabled wall panels are installed from the center outward after marking centerlines for beams and windows.
