Tough and Durable

Isn’t one of your biggest investments worth protecting?

Protecting your investment is easy when you use Thermo-ply® Protective Sheathing on your project. Thermo-ply is manufactured to withstand the most rigorous of job site conditions. Its core is constructed of 4 cross-laminated plies that resist puncture, breakage, and vandalism. Because wall sheathing gets shipped out with the framing package, it’s dumped at the job site with lumber and must withstand a great deal of abuse and rough handling.

Thermo-ply Outperforms Foam and Fiberboard Sheathings in Damage Resistance

Foam and fiberboard sheathings can damage easily, reducing the performance of the wall envelope and increasing costs for replacement and repair. Thermo- ply’s i nhe r en t s t r eng t h stands up to on-site abuses, saving labor and material costs.

Strong and Structural

Make your investment last a lifetime

Thermo-ply® is made to be strong. Thermo-ply’s directionalized fiber and cross-laminated 4 ply construction provide excellent dimensional stability and strength. Our red and blue structural grades provide racking resistance and may be used as an alternative corner bracing method. In addition, Thermo-ply can be used as a draft stop, and also as part of a 1 hour fire rated wall assembly.

Choose the Grade to Fit Your Needs

Thermo-ply is available in 3 different grades

• Green – Lightweight non-structural grade, .078” thickness
• Red – Structural grade for 16” o. c. stud spacing, .113” thick-ness
• Blue – Structural grade for 16” o.c. stud spacing, .137” thickness

*Refer to Individual Evaluation reports (ICC-ES, BOCA, ICBO, SBCCI) for code compliance. Individual jurisdictions and municipalities may vary. Check with your local building officials for approval and acceptance.

Moisture Management

Protection against Water Intrusion

As part of our HomebrellaTM Advanced Moisture Management System, Thermo-ply® Exterior Wall Sheathing is a vital component as it protects the wall envelope and preserves the integrity of what’s inside, i.e., cavity insulation, studs, drywall, etc.
Because of Thermo-ply’s 1/8” thickness, a tight seal is formed to the framing members, producing excellent protection against water intrusion.
Foam and fiberboard sheathings tend to be spongy because of their composition. This makes it difficult to fasten the edges tightly to the wall frame, thus creating gaps and cracks for water to potentially enter.

Outperforming the Competition

Covalence conducted an in-house study that showed that Thermo-ply significantly outperformed OSB sheathing in water resistance. A 24-hour soak test revealed OSB gained almost 30% in moisture and swelled in thickness by 30% while Thermo-ply consistently gained less than 12%.

Water and Weather Resistant Plies

Thermo-ply’s core is composed of high quality, long fibered, specially treated water and weather resistant plies. These plies are pressure laminated with a special water resistant adhesive. Thermo-ply’s moisture content is measured and controlled constantly during the manufacturing process by a computerized system to ensure the highest quality.

Energy Efficient

The Importance of Controlling Air Infiltration

THERMAL PERFORMANCE
Air infiltration can account for over 50% of the heating and cooling energy loss through the walls of a home. Thermo-ply® provides supe-rior protection against air infiltration because when fastened to the framing and studs, its inherent thickness provides the tightest seal of any sheathing material on the market. Cracks and gaps are minimized for air to infiltrate, resulting in improved energy efficiency and lower utility bills.

*Calculations show that just a 1/16” gap around the perimeter of an average home can waste 5 times more energy than can be saved by two inches of additional insulation to the walls of a normally insulated home.

EFFECTIVE R-VALUE IS WHAT COUNTS

Insulative foam sheathings promote their initial high R-value. How much of that R-value is actually retained after it has been installed? Several factors can significantly impact its true performance.

• Foam sheathings age over time and can lose their original R-value. It’s important to refer to aged R-value data in manufacturer’s literature.
• Foam sheathings are fragile and can easily be damaged at the job site by high winds and handling, creating holes and broken corners for air to penetrate if gone unrepaired.
• Foam sheathings are “spongy like” and are difficult to fasten tightly to the wall frame creating gaps for costly air infiltration to penetrate the wall cavity.
• Foam sheathings are non-structural which creates the need for structural bracings. Consequently, when plywood or OSB is used at the corners of the home, the exterior wall cannot “truly” claim the entire added R-value it gets from the foam sheathing when it is only used in the intermediate areas. Plywood and OSB have an R-value of less than 1.
• Fasteners (nails or staples) used to attach foam sheathing to the stud wall creates an effect called “thermal bridging” which can also reduce the sheathing’s original R-value by up to 20%!1

“ Higher R-values and insulation belong in the wall cavity between the studs”

…PROTECT IT WITH THERMO-PLY WALL SHEATHING

Sheathing Performance

Thermo-ply® outperforms other sheathing products which claim to deliver extra R-values.

“Performance in the RealWorld VS a Controlled Laboratory”

One of the most important factors to consider is the sheathing’s ability to do its basic job of controlling heat loss or gain caused by air moving or infiltrating through the walls into the insulation. Thermo-ply retains a much larger percentage of the wall system’s R-value than other sheathing products, which can lose over 50% of the R-value in only a 10 mph breeze.

1. “Affordable Manufactured Housing Through Energy Conservation,” U.S. Depart. of Energy (DOE), July 1984.
2. R-values of wall sections include aluminum siding, sheathing gypsum, airspace, air films, and an assumed R-13 kraft-faced batt insulation. Note: R-value means resistance to heat flow. The higher the R-value the greater the insulating power.

The percentages show the retained, effective R-value for wall sections built with all components being the same EXCEPT the sheathing. This summary on effective R-values is based on air infiltration tests run by an independent laboratory with industry-accepted methods (ASTM E-283), and is further supported by the 1984 Department of Energy report.*

The total static R-value for a Thermo-ply sheath-ing system is a combination of the R-value of Thermo-ply itself and that of the reflective airspace between the sheathing and the siding. The chart on page 7 shows the total R-value resulting from both of these factors for various airspace sizes, using typical siding components.

Thermo-ply and R-values

1. Thermo-ply Reflective Foil System R-values are only for Thermo-ply and the reflective air space between Thermo-ply and siding. Insulation was in complete contact with the inside of Thermo-ply for testing. R-values for siding, cavity insulation, gypsum and air film corrections ARE NOT INCLUDED in Thermo-ply System R-values since many combinations are possible, but they can be added to Thermo-ply System R-value to obtain total Wall R-value. All tests were run according to ASTM C-236 at 75oF mean temperature, 30oF temperature differential.
2. These lapped horizontal sidings form a variable reflective foil airspace with one foil surface on the Thermo-ply. This airspace varies between zero and the thickness or depth of the siding.
3. Brick veneer is installed with 3/4” airspace. Siding must be spaced out 3/4” with furring strips. The airspace is a reflective foil airspace with one foil surface.

Environmentally Friendly

A “GREEN” Building Product

Not just the “in” thing to do
Environmental awareness is affecting the way everyone does business, including the construction industry. Homeowners, builders and architects are always looking for products that are environmentally friendly. Covalence has been using sound environmental policy in the manufacturing of Thermo-ply sheathing since the early 60’s. That’s long before it was considered the “in” thing to do. Our practices have saved tree after tree, forest after forest.
Based on standard measurements from the construction industry, the average 2,500 square-foot house, using thermo-ply sheathing will save 6 trees. In a 50 home development 300 trees!

Since 1976, Covalence estimates we have saved over 9,400,000 trees through our use of recycled materials. Unlike other sheathing materials that use wood in some form or combination, we use no wood chips, no old-growth forests or no fast-growing trees.

Recyclability
Thermo-ply is 99% recyclable. Any Thermo-ply job site waste or scrap can be collected and sent with other recyclable products, saving landfill space, which is a big concern forc builders and communities.

Non-toxic bonding agents – Covalence uses 100% polyvinyl alcohol (PVA) as a bonding agent, PVA is one of the safest bonding agents available, used extensively in the food service industry. It is not a hazardous material (per the American Standard for Precautionary Labeling of Hazardous Industrial Chemicals), and has no known dermal effects. Unlike other sheathing materials, Thermo-ply does not contain asphalts, formaldehyde or phenols that can affect chemically sensitive people.

No CFCs – CFCs (chlorofluorocarbons) have been identified as a danger to the ozone layer surrounding the Earth. Covalence Coated Products uses no CFC’s in the manufacturing of Thermo-ply.

100% Recycled Material
Thermo-ply board fibers are made f r om 1 0 0 % r e -cycled material. This fiber consists of 80& post-con-sumer materials (cardboard boxes, office waste, etc.) and 20% pre-con-sumer mater ial such as mill waste and manufacturing scrap.
