A self-adhering weather-resistant barrier is installed over the existing sheathing of this retrofit home to provide air sealing and a drainage plane before installing new metal and wood siding on the home.
Image
A vapor barrier was installed on the floor of this crawlspace and extended up the walls then the foundation walls were covered with rigid foam.
Image
Any holes through the vapor barrier installed over the basement floor slab are thoroughly sealed as part of the foundation water barrier system.
Image
Brick wall assembly for a hot-humid climate with no Class I vapor retarder and with an air gap (drained cavity) to dissipate vapor driven into the wall by the sun.
Image
Image
Horizontal furring strips are installed over a taped smart membrane that serves as an air and vapor barrier and holds in insulation; the furring strips will provide a nailing surface for tongue-and-groove wood porch ceiling cladding.
Image
Insulating a crawlspace foundation with “cripple wall” in warm climates; in Climate Zones 5+ replace the foil- or plastic-faced fiberglass batt/roll insulation with impermeable rigid insulation or closed-cell spray polyurethane foam
Image
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
Right - A smart vapor barrier wraps the walls and window frames of this home. Seams are taped to provide an air- and water-resistant barrier.
Image
Right - A technician wraps the foundation piers with a vapor retarder in preparation for laying vapor retarder over the floor of this crawlspace.
Image
Right - After wrapping the posts, a technician lays a vapor retarder over the floor of a crawlspace.
Image
Right - House wrap is carefully installed from the top of the roof line to the foundation; seams are overlapped and taped to provide a continuous air- and weather-resistant barrier
Image
Right - Spray foam covers the walls and a sealed vapor retarder lines the floor of this unvented crawl space.
Image
Right - Technicians use adhesive when installing the vapor barrier along the walls of this crawlspace.
Image
Right - The posts and floor of this crawlspace are covered with a heavy sheet of vapor retarder that is sealed to the post, the walls, and at all seams.
Image
Right - This crawlspace, which is insulated on the floor, has a complete vapor barrier over the floor and up the walls that is sealed at all seams and termite inspection gap at the top of the vapor retarder.
Image
Right - This rigid insulation is correctly installed in a level layer over aggregate; the seams will be taped
Image
Right – Half-inch furring strips provide a rain screen and air gap between the weather-resistant membrane and the fiber cement siding on the exterior walls of this marine-climate home.
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
Image
Right – Workers lay radiant floor loops over the concrete reinforcement which is laid over a heavy vapor barrier installed over the sub-slab insulation before the slab is poured.
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
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 below-grade wall assembly includes dampproofing, draining details, and insulation.
Image
The builder’s crews spray foam directly onto the ground to provide a vapor barrier and insulation layer under the slab.
Image
The floor of the sealed insulated crawlspace is covered with a heavy plastic vapor-barrier sheathing that is taped at all seams and around the foundation piers to prevent water vapor from moving into the crawlspace.
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
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.
Image
The polyethylene ground cover in the crawl space is lapped up sides of piers to posts to provide a continuous air and vapor barrier
Image
The polyethylene ground cover in the crawlspace is continuous at interior posts and piers
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 house design in the Hot-Humid climate uses a slab foundation, masonry walls, and an Exterior Insulation Finish System (EIFS) cladding.
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 retarder already applied to the floor of the crawlspace and wrapping up the interior perimeter walls, lapped and sealed at the seams
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
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
Weather resistant barrier is wrapped over the edge from roof to wall sheathing to provide a continuous air barrier at this transition.
Image
When rigid foam insulation is applied to the exterior side of the wall cavity under the cladding, with seams taped and an air gap provided, it acts as a vapor barrier, air barrier, and rain screen.
Image
Wrong - A typical vented crawlspace in North Carolina exhibits water leakage, poor drainage, and a low-quality vapor retarder that does not cover all of the ground surface and is not sealed to the walls.
Image
Wrong - A vapor barrier should cover the top of the concrete block pier support in the crawl space.
Image
Wrong - Class I vapor retarder over framed basement walls can cause condensation, mold, and rotting because plastic prevents drying to the inside; the outside should have waterproofing and vertical drainage, and the framing should be spaced from the wall.
