Foundation wall exterior board insulation with above-grade wall insulation

CAD File

Exterior XPS basement insulation is correctly installed to completely cover the foundation wall

Image

The Perfect Wall includes water, air, thermal, and vapor layers with continuous insulation exterior of the sheathing to reduce the condensation potential in the wall.

Construction Guide - Next Generation High Performance Walls in Climate Zones 3-5, Part II: 2x4 Walls with 1” - 1.5” Exterior Insulative Sheathing

Reference

The Guide addresses walls constructed with 2x4 wood frame studs, wood structural panel (WSP) sheathing as wall bracing and added backing for foam sheathing, a layer of rigid foam sheathing insulation up to 1.5 in. thick over the WSP, and a cladding system installed over the foam sheathing in low...

Right - This concrete basement wall has exterior rigid insulation and comprehensive moisture management details.

Technology Solutions Case Study: Retrofit Measures for Embedded Wood Members in Insulated Mass Masonry Walls

Case Study

Case study describing retrofit measures for embedded wood members in insulated mass masonry walls.

In warm-humid climates, do not install Class 1 vapor retarders on the interior side of air-permeable insulation in above-grade walls, except at shower and tub walls.

Masonry wall interior retrofit with parge coat, fluid-applied water control layer, wood-framed wall with cavity insulation, smart vapor barrier, and wood or metal service cavity

Image

Because the above-grade potions of the wall lack exterior insulation, condensation and even ice form during cold winter conditions

Image

Masonry wall interior retrofit with parge coat, fluid-applied water control layer, rigid mineral wool, wood-framed wall with cavity insulation, smart vapor barrier, and wood or metal service cavity

Image

The builder in this very cold climate installed three layers of unfaced mineral wool batt in the double wall with a code-required vapor barrier between the middle and inner layers of wall insulation that is taped to barriers in the ceiling and floor.

Image

Exterior fiberglass insulation on this new home was (incorrectly) cut to terminate below-grade after backfill, which will expose the above-grade portions of the foundation wall to cold temperatures

Masonry wall interior retrofit with fluid-applied water control layer, spray foam, and wood or metal stud service cavity

Image

Stucco is installed over rigid insulation, which is installed over a drainage plane consisting of a drainage gap and building wrap layer over the sheathing

Image

Foil-faced rigid foam and spray foam can be used to insulate a basement on the interior; use good moisture management techniques to keep the basement dry
