Exterior XPS basement insulation is correctly installed to completely cover the foundation wall
Image
Image
FEMA recommends techniques like open lower wall cavities with exterior rigid foam insulation and paperless drywall for flood-resistant, dryable wall interiors.
Image

Image
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
Image
Furring strips provide drainage gap behind lap siding; screen is added at bottom and top to prevent entry of insects and wildfire embers.
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
House wrap is sealed at all seams and overlaps flashing to serve as a continuous drainage plane over the exterior walls.
Image
Improper flashing can allow rain water into walls, causing significant damage
Image
Image
Install all layers of the drainage plane to overlap, not underlap, to direct bulk water down and out of the wall.
Image
Image
Install furring strips over house wrap to provide a rainscreen behind wood siding.
Image
Image
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

Image
Right – The ties are bent at a 90 degree angle at the nail head and embedded into the mortar joint at least 1.5 inches.
Image
Right - Basement slab with a capillary break of either gravel or a drainage mat.
Image
Right - Below-grade concrete has been properly sealed against moisture and is now having insulation installed.
Image
Right - Furring strips create an air gap to allow penetrating moisture to drain instead of wicking into walls; they also provide a nailing surface for siding.
Image
Right - House wrap is overlapped “shingle” style to direct moisture down and away from the house; seams will be taped so house wrap serves as both an air and weather barrier.
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
Image
Right - Tape flashing keeps moisture out around and below the window; extra tape reinforces the corners to prevent tearing of the house wrap and to keep water out of this critical juncture.
