The sheathing helps meet or exceed building code requirements and comes in four thicknesses with R-3, R-6, R-9, and R-12 insulation values, respectively. It is nailable and can be flashed using common tools.
Air and Water Barrier System / Georgia-Pacific Wood Products
The ForceField air and water barrier system consists of structural engineered wood sheathing panels laminated with an air and water barrier. When paired with ForceField seam tape, the system creates a code-compliant, integrated building envelope that eliminates the need for housewrap and keeps out water and air while allowing water vapor to escape. Panels are 7/16-inch thick and are available in 4x8-, 4x9-, and 4x10-foot sizes.
Spray Foam Insulation / Icynene
Icynene’s Classic Ultra spray foam is an open-cell foam insulation with greater cohesion than the company’s past products. The GreenGuard Gold-certified insulation can be sprayed in a wide variety of temperatures, making it appropriate for any climate, the company claims. It achieves an R-value of 3.7 per inch and has a core density of 0.5 pound per cubic foot.
Radiant Barrier Sheathing / LP Building Solutions
TechShield radiant barrier sheathing consists of a thin layer of aluminum laminated onto the company’s traditional sheathing and is designed to block up to 97% of the radiant heat coming into attics, cooling the spaces by up to 30° F. Panels are 47 7/8 inches by 95 7/8 inches in size. Radiant sheathing can help builders qualify for green building credits and can lower HERS scores.
Modular Living / Stuga
Stuga builds modular living environments in the minimalist Scandinavian tradition. Structures can act as one-bedroom accessory dwelling units or be combined to create larger homes. They are permit-ready and meet the building codes of many U.S. cities. The Shift (shown) is a one-bedroom, one-bath unit with two roughly 300-square-foot modules offset to make room for outdoor living. Several finish packages are available.
Wood Protection / Nisus
Bora-Care with Mold-Care is the company’s classic termite-control treatment with added protection against mold and fungi. According to Nisus, the borate-based wood preservative requires a single application to diffuse into the wood in a house and create a protective barrier. It can be applied either directly during the dry-in phase of construction or to high-risk areas after construction.
Engineered Wood Products / Boise Cascade
Not only does Boise Cascade manufacture engineered wood products, plywood, and lumber, but it also distributes building supplies across the U.S. and offers software tools for managing workflow, design processes, and material estimates. Boise recently reintroduced its 2.1E Versa-Lam laminated veneer lumber (shown), with increased modulus of elasticity grades for both beams and headers.
Subfloor Adhesive / Huber Engineered Woods
AdvanTech subfloor adhesive is a foam-to-gel polyurethane that can connect framing members to AdvanTech flooring, traditional OSB, or plywood subflooring, preventing movement between elements and minimizing floor squeaks. The adhesive provides eight times more coverage than traditional caulk adhesive, Huber says, and can be applied to dry, frozen, or wet lumber.
Engineered Lumber / LP Building Solutions
LP SolidStart Laminated Strand Lumber (LSL) is an engineered lumber product that installs like traditional lumber but offers greater strength and consistency. Hardwood strands are pressed to a low moisture content, reducing shrinkage, warping, and twisting of the product. It’s available in grades of 1.35E, 1.55E, and 1.75E and in custom end-trimmed lengths upon request.
Subfloor / LP Building Solutions
LP Legacy OSB subfloor uses Gorilla Glue waterproof resins to coat and bind wood for improved moisture performance. The panel’s high density makes it ideal for hardwood floors, tile applications, and projects where the subfloor may be exposed during construction. According to LP, the subfloor offers superior fastener-holding strength and is quieter underfoot than other options.
Termite Pretreat / Nisus
Bora-Care’s spray treatment protects against termites and other wood-destroying pests by making the wood elements inedible. The treatment can help earn points toward LEED or National Green Building Standard certification and can save builders a day of cycle time while keeping chemicals out of the soil, the company says. The borate-based treatment remains effective for the life of the home.
Concrete Mix / Quikrete
Quikrete Q-Max Pro Concrete Mix is a fiber-reinforced concrete formulated to provide 1 hour of working time and a walk-on time of 3 hours. It can achieve a compressive strength of 6,500 psi and resists drying shrinkage cracks, the company says. The product is air entrained for durability during freeze-thaw cycles. It’s available in an 80-pound bag and can be used for slabs, steps, walls, floors, and more.
Sheathing and Tape / Huber Engineered Woods
The Zip System structural roof and wall system consists of sheathing and tape with an integrated air- and water-resistive barrier to streamline the weatherization process by eliminating the need for housewrap. Panels are installed and then taped to seal the seams, which contributes to a building’s energy efficiency by forming a continuous rigid air barrier that reduces air leaks.
Insulated Concrete Forms / Nudura
Nudura’s insulated concrete form (ICF) series creates a complete building envelope with one product that integrates the form system, wall structure, insulation, air barrier, vapor control barrier, and interior and exterior fixing points. Made up of two expanded polystyrene foam panels connected by a 100% recyclable web system, the ICFs improve energy efficiency and can help achieve LEED certification, the company says.
