Image
A continuous layer of polyethylene covers the crawlspace floor and is attached to the wall with wood nailing strips
Image
A paint-on waterproofing covers the exterior and tops of the concrete block foundation walls and piers to block moisture moving up through the concrete, while foil-faced R-13 insulation lines the inside surface of the exterior walls.
Image
A roof drain is installed in an existing flat roof retrofitted with above-deck rigid foam insulation that is integrated with new air and water control layers
Image
Because the above-grade potions of the wall lack exterior insulation, condensation and even ice form during cold winter conditions
Image
Capillary break at all crawlspace floors using ≥ 6 mil polyethylene sheeting, lapped 6-12 in., and lapped up each wall or pier and fastened with furring strips or equivalent
Image
Closed-cell foam is sprayed into roof cavities along the masonry parapet wall to form a continuous air barrier between the wall and the sheathing of the flat roof
Image
Closed-cell spray foam fills the roof joist cavities forming an air barrier between the masonry parapet wall and the roof sheathing
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
Image
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
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
Image
Exterior XPS basement insulation is correctly installed to completely cover the foundation wall
Image
Extruded polystyrene (XPS) rigid foam is taped at the seams to provides a continuous air and weather-resistant barrier so no house wrap is needed; it also provides a continuous layer of insulation.
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
Image
Image
Good water management practices like sloping grade away from house, and installing gutters, perimeter drain pipe, a capillary break, and free-draining soils or drainage mat protect the foundation from water saturation.
Image
ICF bricks are stacked to form hollow walls that are reinforced with steel rebar before the concrete is poured in
Image

Image
Over the taped rigid foam board, 2x4 furring strips provide a ventilating air gap and drainage plane under the engineered wood lap siding. The furring strips were attached with structural screws to provide an attachment surface for the siding.
Image
Polyethylene completely covers the floor of this crawlspace and is attached to the walls and piers as well
Image
Polyethylene is being attached to the crawlspace floor and walls with plywood furring strips
Image
Polyisocyanurate rigid foam insulation is installed in multiple layers with staggered, taped seams over the flat roof
Image
Image
Proper flashing around windows is especially important when the rigid foam serves as the drainage plane in the wall
Image
Provide flashing and sealing integrated with the air and water control layers for vents and other roof penetrations
Image
Retrofit an existing roof by installing rigid foam, new moisture and air control layers, new sheathing, and new cladding plus cavity insulation in the roof rafters to create an unvented attic
Image
Right - Basement slab with a capillary break of either gravel or a drainage mat.
Image
Right - Retrofit of an existing basement slab by adding dimple plastic mat, rigid foam insulation, and a floating subfloor.
Image
Right - The basement walls are wrapped with 3 inches of XPS rigid foam that will be taped at the seams then covered with a dimpled plastic water barrier.
Image
Right - The existing basement slab is retrofitted by installing a dimple plastic drainage mat, rigid foam insulation, and a floating subfloor.
Image
Right - These roof insulation panels are installed in multiple layers with joints offset both vertically and horizontally. The plywood nail base fastened to the roof framing holds the insulation layers together snuggly thus minimizing gaps
Image
Right – A 1-inch layer of XPS rigid foam covers the 2x6 wall studs and is topped by ½-inch-thick plywood sheathing, which is covered with draining house wrap and serves as a nailing surface for siding and trim.
Image
Right – Even house wrap is installed in the factory for these modular homes where each floor is factory assembled.
Image
Right – Furring strips provide a drainage and ventilation gap between the siding and the cork insulation.
Image
Right – Furring strips provide a drainage gap between the rigid foam and the siding.
Image
Right – Furring strips were installed to provide a 3/8-inch drainage plane over the rigid foam and under the fiber cement lap siding.
Image
Right – Polyethylene sheeting vapor barrier is installed and sealed to the crawlspace walls with mastic
Image
Right – Ripped OSB provides furring strips for a ventilation gap behind the wood siding.
Image
Right: All joints in the rigid foam are taped to keep stucco out of joints for even drying. Mesh tape (shown here) is used with expanded polystyrene (EPS); acrylic sheathing tape or self-adhered membrane is used with XPS
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
Rigid insulation and water control layers are installed on the exterior of a flat foundation wall; spray foam insulates the rim joist
Image
Rigid mineral wool insulation is covered with ¼-inch wood battens which provides a air and drainage gap under the cedar and fiber cement siding.
Image
Roofing membrane is installed over polyisocyanurate rigid foam insulation and insulation cover board that has been cut to fit around locations for blocking for the PV system rack
Image
Roofing paper protects the top of the new plywood parapet while the base of the parapet is air sealed with spray foam and fibrous insulation is installed in the rafter cavities in this flat roof retrofit
Image
Seams in the ICF block are sealed so the EPS foam surface can serve as the drainage plane; no house wrap is needed.
Image
Spray foam extends down the foundation wall to the slab, which has been retrofitted by adding dimple plastic drainage mat and rigid foam insulation.
Image
Spray foam extends down the inside of the foundation wall to the uninsulated slab; because the wall lacked exterior perimeter drainage, the slab was cut and an interior footing drain was installed.
