Image
A concrete slab-on-grade foundation with exterior insulation, which can be elevated above the local grade as a flood-prevention strategy.
Image
Image
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

Image
Image
Crawl space interior insulation with EPS or XPS semi-permeable insulation on inside wall
Image
Image
Exterior XPS basement insulation is correctly installed to completely cover the foundation wall
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
ICF bricks are stacked to form hollow walls that are reinforced with steel rebar before the concrete is poured in
Image
Image
Pest proofing of this unvented crawlspace includes a metal termite shield that extends out from the sill plate, metal flashing wrapping the bottom of exterior rigid foam, and a termite inspection gap above interior rigid foam.
Image
Right - Potential locations for crawlspace insulation: vapor sheeting should always cover the floor with insulation (a) outside walls, (b) inside walls, (c) both sides of walls, (d) sandwiched inside walls, or (e) under the first floor.
Image
Right - Spray foam insulates and air-seals the stone walls of this unvented crawlspace.
Image
Right - This unvented crawlspace is insulated along interior walls with rigid foam and air-sealed by covering the floor with vapor retarder that is sealed to the rigid foam which is taped at the seams.
Image
Right - This unvented crawlspace is insulated along the walls and between the floor joists with 2-inch foil-faced polyisocyanurate; a termite inspection gap is visible above of the wall insulation and below the band joist.
Image
Right – Polyethylene sheeting vapor barrier is installed and sealed to the crawlspace walls with mastic
Image
Right – Spray foam insulation was sprayed onto the ground and along the sides of the foundation walls and piers of this insulated crawl space.
Image
Rigid foam insulation and a thin slab were installed over the dirt and gravel of this sealed crawlspace
Image
Rigid foam insulation applied to the crawlspace walls, allowing a 3-in. pest control inspection strip at the top
Image
Image
Image
The sealed, insulated crawlspace is a clean, dry location to house the main floor heating ducts and also provides bonus storage space.
Image
Image
This floor assembly above a vented crawlspace controls vapor and heat transmission by using foil-faced isocyanurate rigid foam insulation installed underneath the floor joists and fiberglass insulation in the floor joist cavities
Image
This house with interior insulated crawlspace is protected from pests with termite shield at sill plate, borate-treated framing, flashing at end of wall insulation, and a termite inspection gap at the top of the rigid foam
Image
Unvented air-sealed crawlspace is insulated along the perimeter walls with rigid foam
Image
Unvented crawl space with interior insulation - designed for termite resistance in heavily infested areas
Image
Image
Image
Image
Wrong – A clothes dryer that vents to the crawlspace can contribute moisture to the crawlspace; this can result in damp, molding, and rotting insulation
Image
Wrong – The polyethylene sheeting vapor barrier is not attached to the piers with mechanical fasteners
