Expert Meeting Report: Interior Insulation Retrofit of Mass Masonry Wall Assemblies

Reference

Expert Meeting about interior insulation retrofit of mass masonry wall assemblies held on July 30, 2011.

This flood-resistant masonry wall design with metal framing and rigid foam insulation will limit moisture damage in exterior walls.

Image

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

Image

FEMA recommends techniques like open lower wall cavities with exterior rigid foam insulation and paperless drywall for flood-resistant, dryable wall interiors.

Image

Concrete is poured into the rigid foam shell of the insulated concrete form (ICF) walls; a plastic water barrier has already been installed to protect the below-grade wall surfaces.

Image

Right – The rigid insulation covers all exterior walls and all seams are taped to provide a complete drainage system

Image

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

Image

Step 5. Apply self-adhesive flashing over top edge of the wall flashing, diverter, and rigid foam insulation

Image

This house design in the Hot-Humid climate uses a slab foundation, masonry walls, and an Exterior Insulation Finish System (EIFS) cladding.

Image

Vapor-permeable mineral wool insulation is installed on the exterior side of the sill beam during an exterior wall retrofit to allow the sill beam to dry to the outside

Image

Exterior surface of below-grade walls finished as follows: For poured concrete, concrete masonry, and insulated concrete forms, finish with damp-proof coating

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

Existing low-slope (“flat”) roof and brick masonry walls with a new fully adhered air barrier membrane plus polyisocyanurate rigid foam insulation and a roofing membrane water control layer

Image

Existing flat roof and wood-framed walls are retrofitted with a new fully adhered air barrier membrane plus polyisocyanurate rigid foam insulation and a roofing membrane water control layer

Image

Right - Permeable rigid mineral wool insulation and appropriate water-management flashing details are integrated with new rigid foam siding to keep water away from the sill beam above the foundation wall
