An impermeable, self-adhered sheet designed for use as a rough-opening flashing and transition membrane for connecting dissimilar materials to maintain air and moisture barrier continuity.
A detailing compound that protects wall rough openings, penetrations, sheathing fasteners and seams. It eliminates the need for joint reinforcing tape and reduces installation time.
A high-performance, self-adhered flashing tape used to treat roof joints and seams. Made with an acrylic adhesive and proprietary film, this tape offers exceptional durability and tear resistance once installed.
A semi-rigid polypropylene seal that creates a “living hinge.” It simplifies the detailing of inside and outside exterior wall corners, protecting structures against air and water intrusion in some of what are typically the most difficult areas to treat.
A conformable, peel-and-stick flashing tape. It wraps easily around windows and other curved and rough openings. It is ideal for use on curved openings on walls and windowsill pan flashing.
An advanced seam tape specially designed for treating wall seams, joints and detailing penetrations. It helps contribute to the continuity of the air and moisture barrier on residential structures.
A radiant barrier is a layer of reflecting aluminum placed in an airspace to block radiant heat transfer between a heat-radiating surface (such as a hot roof) and a heat-absorbing surface (such as conventional attic insulation and your ceilings).
DensArmor Plus® interior panels do not have a water-stopping surface coating. The coating on DensShield® tile backer provides a water barrier to stop moisture from penetrating into the product and wall. DensShield tile backer is made to be used in wet areas such as showers and tub areas as a substrate for ceramic tile. DensShield tile backer is manufactured to meet ASTM C 1178. DensArmor Plus interior panels feature a tapered edge for joint finishing while DensShield tile backer has a square edge.
No. The grey face (tile side) of DensShield Tile Backer has a heat cured acrylic coating which is a built-in moisture barrier and vapor retarder so that no additional moisture barrier is required. In fact, an additional moisture barrier to the back side of DensShield Tile Backer is NOT recommended. Prior to the tile installation it is permissible to apply a fluid applied membrane to the face of DensShield Tile Backer for enhanced moisture resistance.
Both use fiberglass mats as the back facer material. When installed against the wall framing, both products provide a fiberglass mat surface facing the wall cavity that resists possible mold growth on the back of the panel. DensShield® tile backer and DensArmor Plus® panels both have cores that are moisture resistant, manufactured to ASTM C 1396, section 7 specifications.
No special or unique fasteners are required to fasten DensShield Tile Backer panels in place. For wood studs: galvanized roofing nails, rust-resistant drywall screws or bugle head deck screws. Fasteners should be long enough to penetrate at least 3⁄4 (19 mm) into the wood framing members. For metal framing: a variety of rust-resistant screws can be used.
You may also find that radiant barriers can expand the use of space in your home. For instance, un-insulated, unconditioned spaces such as garages, porches, and workrooms can be more comfortable with radiant barriers. Because radiant barriers help keep attics cooler, the space is more usable for storage. You can also use radiant barrier sheathing on exterior, south-facing walls that have uninterrupted sun exposure. In a wall application, the foil side of the radiant
barrier sheathing must be installed with the foil facing the outside. The foil must also have minimum 3/4″ airspace in front of it to be effective. This can be accomplished by using furring strips on the outside of the sheathing to create the 3/4″ airspace between the sheathing’s foil face and the siding, brick or other material used on the exterior of the wall. Be sure to check with your local building codes for compliance in the installation of any siding product. You may also want to check with your siding manufacturer for the use of their siding in conjunction with radiant barrier sheathing.
The Reflective Insulation Manufacturers Association (RIMA) has published Technical Bulletin #103, which reports that in peak summer conditions, the temperature of asphalt shingles is increased only an average of 2 to 5° F over radiant barrier roof sheathing. This is not a significant temperature rise and most shingle manufacturers have indicated that it does not affect their shingle warranties. However, you may wish to review your warranty to be sure it will not be voided. Contact your shingle manufacturer directly with any questions and ask for any changes in coverage to be provided in writing.
Apply Thermostat radiant barrier sheathing with the reflective (foil) side down towards the attic, directly to the roof framing. For radiant barrier sheathing to be effective long-term, the reflective side must have a minimum 3/4″ air space in front of the foil face to properly reflect radiant heat. This applies to both attic areas and cathedral type ceilings.
Yes. Both 1 ⁄4” (6.4 mm) and 1 ⁄2” (12.7 mm) DensShield® Tile Backer can be used in floor applications. Both of these thicknesses passed the Robinson Floor Test, the industry standard floor test for residential and light commercial ratings. The Robinson Floor Test (ASTM C627) is designed to determine how a tile assembly holds up under extreme wear and weight conditions. DensShield Tile Backer achieves the same light commercial rating as cement and fiber cement backers.
No. DensShield Tile Backer requires the same type of setting materials as any other backer board. No special mastics or thin-sets are required. To set tile, use a latex-Portland cement mortar, or other products recommended by the mortar manufacturer. Follow the tile setting manufacturer’s instructions for applying tile setting material. Dry-set or thin-set latex-modified mortars are most commonly used with DensShield Tile Backer and cement backers. Use only latex-modified mortars in floor applications.
Yes. In many applications, DensShield Tile Backer is used for its moisture barrier and moisture-resistant qualities for non-tiled walls and ceilings. There are several methods for finishing the panel depending on the environment. The environments of non-wet, high humidity and wet areas are described in the DensShield Tile Backer technical brochure. Each environment has its own finishing recommendation. A finishing method must never be used in a more severe environment than described.
Yes. The flexural strength of DensShield Tile Backer panels is approximately the same in both parallel and perpendicular directions. This allows wall and ceiling applications to be installed either parallel or perpendicular to the supporting members and results in fewer panel joints. DensShield Tile Backer can be installed over both wood framing and steel stud construction by spacing fasteners 6” (152 mm) o.c. along studs for wood or a minimum 20-guage (33 mils) steel framing.*
*For equivalent and effective guage steel studs, we have no evaluation or installation recommendations.
Yes. The DensShield® Tile Backer panel should be positioned next to framing with the acrylic coated (grey) side facing away from studs. Apply mortar or mastic and tile to the acrylic coated (grey) side of DensShield Tile Backer panels. The built-in acrylic coating stops moisture penetration at the surface.
Yes, Thermostat radiant barrier sheathing can be used in both types of construction as long as you maintain a minimum 3/4″ airspace for the foil surface. In both cases, the foil face should be installed facing down.
Energy usage varies according to many factors, including individual preferences and the fluctuation of energy costs in general. The amount of energy consumed is directly related to:
Yes. Thermostat radiant barrier sheathing is designed to work with, not in lieu of, standard attic insulation. Conventional insulations such as fiberglass, cellulose, foam and others do not insulate against radiant heat transfers.

DensShield Tile Backer is rated for residential and light commercial floors. 1⁄4” (6.4 mm) DensShield Tile Backer panels have a compressive strength of approximately 1200-1500 lbs psi, and 1⁄2” (12.7 mm) DensShield Tile Backer has a compressive strength of between 450 and 600 lbs psi. That means that it would typically take a load of 450 to 600 lbs psi to start to crush 1⁄2” (12.7 mm) DensShield Tile Backer. When a load is applied to the floor tile, the tile distributes the load over its entire area.
No. Fasteners should be flush with the coated surface and are not to be countersunk.
Yes. 5⁄8” (15.9 mm) DensShield® Fireguard® Tile Backer is manufactured to meet Type X requirements (per ASTM C1178) and can be substituted in any generic assemblies using a 5⁄8” (15.9 mm) Type X gypsum board. This permits the use of numerous 1-hour and 2-hour assemblies for both wood and metal frame construction. Transition to regular 5⁄89 (15.9 mm) Type X board is also minimized.
