Heat loss often occurs where interior walls intersect with exterior walls in traditionally built homes because the additional studs required for nailing drywall leave minimal space for insulation. In contrast, high-efficiency wall intersections use techniques that require less wood, provide required nailing surfaces for drywall that meet at the corners, and allow more space for insulation. One method uses horizontal pieces of framing between the two exterior wall studs where an interior wall will intersect. This creates an appearance like a ladder. Another method uses a metal plate to connect the tops of the intersecting walls, along with clips on the studs to secure the drywall.
