Modular wall system with internal air and vapor barrier joints

Abstract

Pre-fabricated panels may consist of multiple layers of materials, which may include (from outside to inside): exterior outer cladding, insulation material, air and vapor barrier (AVB), sheathing board, spray home and studs. In one example, each edge of a sheathing board on the interior side of a wall may be covered by a U-shaped sleeve made of soft plastic, for example rubber, forming a flexible joint between abutting sheathing boards. The edges of the sheathing boards are connected by an interior lap seal system that allows for the application of a sealant through an injection portal. A strip of peel and stick membrane may be applied over the lap seal system as a secondary measure of continuing the AVB membrane. A stud framing system may be used to ensure there is sufficient space to allow the application of AVB membrane from the inside.
