Adding air-sealing and rigid foam insulation at the wall-to-overhanging floor juncture at the outside corner of an existing home
Image
After setting precast concrete basement walls on an 8-inch bed of trap rock, this builder sprayed 2 inches of closed-cell spray foam directly onto the ground then laid piping for radiant floor heating before pouring the concrete floor slab.

Image
Image
Closed-cell spray foam insulation covers the attic floor to provide a continuous air control layer.
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
Install rigid insulation and finish material below the framing and cavity insulation of a building overhang

Image
Right - Closed-cell spray foam covers the ceiling and joists to insulate and air-seal the ceiling deck.
Image
Right - Foil-faced polyisocyanurate insulating rigid foam sheathing is installed below the floor framing of this house built on piers; however, the seams should be sealed with metal taped and the plumbing elevated and protected.
Image
Right - Foil-faced polyisocyanurate insulating rigid foam sheathing is installed rather than fibrous insulation below the floor framing of this house built on piers
Image
Right - Retrofit of an existing basement slab by adding dimple plastic mat, rigid foam insulation, and a floating subfloor.
Image
Right - Spray foam insulation air-seals the ceiling-to-drywall seams at the wall top plate.
Image
Right - The existing basement slab is retrofitted by installing a dimple plastic drainage mat, rigid foam insulation, and a floating subfloor.
Image
Right - The rigid metal HVAC ducting is installed between the floor joists rather than in an unconditioned attic or crawl space to minimize heat loss.
Image
Image
Right – Spray foam insulation fills the header above the door and fills the rim joist between floors.
Image
Right-- IR photo shows how effectively spray foam insulated/air sealed attic kneewall and the floor cavities under kneewall
Image
Rigid foam insulation and a thin slab were installed over the dirt and gravel of this sealed crawlspace
Image
The application of intumescent coating/protection layer protects this elevated floor system from below.
Image
The attic kneewall and the open floor cavities under kneewall are both sealed and insulated in one step with spray foam insulation
Image
The ceiling over an unconditioned space is insulated with closed-cell spray foam that fills the ceiling cavities and encapsulates the framing
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.
