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
Right - This rigid insulation is correctly installed in a level layer over aggregate; the seams will be taped
Image
Right – Prepoured foundation panels with integrated insulation and vapor barrier are installed in place.
Image
Right – The basement of this cold-climate home is insulated along interior walls with 2 inches of foil-faced rigid foam; finished basement walls also have a 2x4 interior wall insulated with R-19 blown-in fiberglass insulation and a poly vapor barrier.
Image
Right – The raised slab foundation has a 3-ft stem wall of filled concrete block, then is back-filled with compacted dirt and crushed rock, then insulated with 1” rigid foam covered with taped vapor barrier, under a floor slab.
Image
Right – Workers pour the concrete for the basement floor slab over a vapor barrier installed over rigid foam.
Image
Right-Polyethylene sheeting is correctly installed over aggregate and taped to pillars and foundation wall
Image
Rigid foam insulation can serve as the drainage plane when all seams are taped. Furring strips provide an air gap behind the cladding.
Image
The “institutional” perfect wall works in all climate zones; water, air, vapor, and thermal control layers are exterior of the sheathing, assembly allows drying to interior and exterior
Image
The builder’s crews spray foam directly onto the ground to provide a vapor barrier and insulation layer under the slab.
Image
The Larsen-truss 9-inch wall cavities were covered with a smart vapor membrane that was fastened to the trusses with furring strips, which also provide an air gap behind the wood siding; each truss cavity is then filled with blown cellulose.
Image
This exterior wall retrofit permits drying to the exterior of a sill plate installed on an untreated flat foundation wall
Image
This exterior wall retrofit permits drying to the exterior of a sill plate installed on an untreated irregular foundation wall
Image
This Texas homes uses a slab foundation including a 4-in.-thick post-tensioned monolithic slab with turned-down edges poured over a 6-mil polyethylene vapor barrier and capillary break; slab edge insulation is not used due to termite risk.
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
Walls in cold climates with a Class 3 vapor retarder (latex paint) and a vapor-open continuous insulation like mineral wool allow drying to the interior or the exterior
Image
Walls in cold climates with a polyethylene vapor barrier interior of the wall cavity should have either no exterior insulation or a vapor-open continuous insulation like mineral wool that allows drying to the exterior
Image
Image
Wrong - Polyethylene sheeting should be lapped up sides of walls and pillars and taped
Image
Wrong - The fiberglass blanket insulation has no perforated vapor retarder, does not cover the entire basement wall, is not sealed at the edges, and is not installed over rigid foam.
