interior drywall; possibly a vapor barrier (e.g. poly sheeting), though the wisdom of this is debatable (see the comment from iLikeDirt below); wall studs (optionally with batt or cellulose insulation in between); exterior sheathing; rigid foam; wooden strapping for attaching siding, screwed to studs through foam
Some builders use 1 2-inch wood sheathing (R-0.6) or asphalt impregnated sheathing, usually called blackboard (R-1.3) to sheath the walls. By using a 1 2-inch foam insulated sheathing (R-2 to R-3.5) in combination with wall cavity insulation, the total R-value of the exterior wall will be increased, contributing to greater
All ThermalCal Wall panel sizes are nominal 4' x 8' (1.22 m x 2.44 m). The actual coverage is approximately 47-1 4” x 96” (1.20 m x 2.44 m). The edges of wood sheathing are rabetted or cut back to allow for expansion with foam edges machined into a tongue and groove profile. ThermaCal Wall panels are NOT
One new idea relating to enclosure design is to use exterior foam insulating sheathing as the primary sheathing and drainage plane for the wall assembly. However, as with any building enclosure system, proper details for the management of water, vapor, and energy transfer is critical. Window systems need to be installed

Insulating With Exterior Spray Foam. Well-Insulated Foundation. I've found that when a customer wants a finished basement, ICFs are the most cost-effective way to build the foundation walls; they're easier to finish than poured concrete walls and can be installed by my own crew. For my house we used 11-inch-wide.
How to attach exterior wall cladding through foam plastic sheathing to wood or steel framing.
BUILDING AMERICA (BA) has been advocating the use of rigid foam sheathing insulation for years as a means to improve the home's thermal envelope, by increasing R-value while minimizing thermal bridging in wood-framed walls. Research by several teams has provided the critical scientific basis for
Non-foil-faced panels are generally recommended beneath aluminum, vinyl, and wood-based sidings. Most foam and cellulose panels are extremely lightweight and capable of being cut with a utility knife. Nail the panels to wall studs with large-headed galvanized nails long enough to penetrate studs by at
Nailing wood siding directly to foam doesn't work because nails have to be extra long to reach through the siding and foam to a solid nail base. Long nails have a larger diameter . One-inch thick foam can be used to sheath the remainder of the house, leaving the exterior wall surface flush. Each corner panel will resist an
Rigid foam sheathing is a form of insulation that's applied to the exterior of the building. Since it's used in conjunction with traditional wood sheathing and interior insulation, some builders may wonder what the point is. In order to get And it may put off or prevent costly work to repair rot in walls or framing.
On our first homes in New Orleans, Make It Right used standard wooden stud exterior walls and advanced framing construction. We glued and nailed the exterior sheathing and used spray foam insulation in the interior wall cavity. We tested these walls for impact resistance and they performed much better
If you have drafts and cold walls you may have no insulation or poor insulation in your walls. Learn about injection foam insulation for your existing walls.
(For more information on this topic, see “Calculating the Minimum Thickness of Rigid Foam Sheathing.”) In fact, research has shown that the type of wood-framed wall with the driest sheathing is a wall with an adequately thick layer of continuous exterior insulation. Once builders understood the building
For the past 30 years, the majority of new homes in the U.S. have been built with wood-framed walls sheathed with oriented strand board (OSB). Builders who install a continuous layer of rigid foam insulation on the exterior side of their walls often install the foam over OSB or plywood sheathing. However

Wood framing typically constitutes 25% of the surface area of walls, so the proper installation of insulated foam sheathing can prevent thermal bridging and
