For slabs on grade in CZ 4 and higher, 100% of slab edge insulated to ≥ R-5 at the depth specified by the 2009 IECC and aligned with thermal boundary of the walls
Image
Four inches of rigid foam separate the concrete slab from the ground and the foundation walls.
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 foundation walls wrap the floor slab in R-22 of insulation while the entire space under the slab is covered with 4.3 inches of closed-cell spray foam.

Image
Right - Additional potential locations for slab-on-grade insulation include (a) under the slab and outside the perimeter with optional underground moisture block, (b) under the whole foundation, or (c) on top of the slab.
Image
Right - Basement slab with a capillary break of either gravel or a drainage mat.
Image
Right - Potential locations for slab-on-grade stem insulation in new construction: slab insulation should always be underneath, with stem walls insulated (a) inside, (b) outside, (c) not at all, or (d) outside with underground extension to repel moisture.
Image
Right - Retrofit of an existing basement slab by adding dimple plastic mat, rigid foam insulation, and a floating subfloor.
Image
Right - Rigid foam is installed over a waterproofing membrane that has been applied to the basement foundation walls.
Image
Right - The existing basement slab is retrofitted by installing a dimple plastic drainage mat, rigid foam insulation, and a floating subfloor.
Image
Image
Right - This rigid insulation is correctly installed in a level layer over aggregate; the seams will be taped
Image
Right - Workers installed rigid foam on the floor and the sill plates of these pre-cast, pre-insulated concrete wall panels to provide a continuous layer of insulation under and around the not-yet-poured basement floor slab.
Image
Right – After installing the insulated concrete foundation wall panels, the builder installed underslab rigid foam, which was topped by 4 inches of crushed rock then the poured slab.
Image
Right – Insulated concrete forms (ICFs) provide the insulated stem wall for the slab-on-grade foundation for this SIP house.
Image
Right – R-20 of XPS and polyiso rigid foam were added on the slab shelf that is part of this precast foundation wall system.
Image
Image
Right – Rigid foam was attached to the tops of the precast foundation walls to form an insulated edge for the floor slab.
Image
Image
Image
Right – This wall is constructed with the sill plate overhanging the top of the foundation wall so that when rigid foam is installed on the exterior of the foundation wall, its surface will align with the surface of the wall sheathing.
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 extends under the full slab and lines the inside edges of the foundation walls.
Image
Rigid foam insulation and a thin slab were installed over the dirt and gravel of this sealed crawlspace
Image
Image
Rigid insulation and water control layers are installed on the exterior of a flat foundation wall; spray foam insulates the rim joist

Image
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.
Image
Spray foam insulation extends down the foundation wall to the slab, which has been retrofitted by cutting the slab to install drainage mat against the wall and a new perimeter footing drain, along with rigid foam plastic above the slab.
Image
The basement is constructed with precast concrete walls lined with R-21.3 foil-faced rigid foam while an R-10 layer of XPS rigid foam covers the ground under the slab.
Image
The basement slab is wrapped in a blanket of insulation including R-27 of closed-cell spray foam under the slab and R-22 ICF blocks wrapping the slab edges.
Image
The builder laid down a 4-inch base of aggregate rock, then covered that with a plastic vapor barrier that is taped at all seams and around all penetrations before installing the rigid foam under-slab 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 existing slab is retrofitted by coating with epoxy paint, then installing rigid foam insulation and a floating subfloor.
Image
The existing slab is retrofitted with epoxy paint, rigid foam insulation, sleepers (furring strips), and subfloor.
Image
The floor slab is completely insulated with ICF foundation walls and R-20 (3 inches) of closed-cell foam that is sprayed directly onto the ground before pouring the slab.
Image
The foundation walls are ICF block providing two continuous layers (R-23) of insulation around the slab, which will sit on an additional 4 inches (R-20) of low-VOC EPS foam.
Image
The home’s slab-on-grade foundation is wrapped in a blanket of rigid foam extending completely under the slab and along the edges.
Image
This exterior insulated slab-on-grade monolithic grade beam foundation is protected from pests by termite shield at the sill plate, borate-treated framing, flashing at end of wall insulation, brick veneer over slab-edge insulation, and rock ground cover.
Image
This house with an insulated slab is protected from pests with a termite shield at the sill plate, borate-treated framing, insect screen covering bottom of furring air gap, and brick veneer over slab-edge insulation
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.
