Description
DensGlass
®
Sheathing is a gypsum panel made of a treated, water-resistant
core, surfaced with fiberglass mats and a GOLD colored primer coating. Providing
superb protection from the elements, DensGlass Sheathing is resistant to
delamination and deterioration due to weather exposure
— even during construction
delays that last as long as twelve months after installation and are backed by a
limited warranty against delamination and deterioration for up to 12 months of
exposure to normal weather conditions.* DensGlass Sheathing panels are also
mold-resistant,
and have scored a 10, the highest level of performance for mold
resistance under ASTM D3273 test method
.
DensGlass Sheathing exhibits a dimensional stability that assures resistance to warping,
rippling, buckling and sagging for a flat and even substrate and is noncombustible
as defined and tested in accordance with ASTM E136 or CAN/ULC S114. Since
DensGlass Sheathing is strong in both directions, it may be installed either
parallel or perpendicular to wall framing members (always follow specific
assembly installation instructions).
Primary Uses
Because of the superior performance of DensGlass Sheathing, it is specified for
exterior walls, ceilings and soffits in a wide variety of applications. These include
exterior insulation and finish systems (EIFS); cavity brick or stone veneer applications;
cladding such as wood siding, vinyl siding, composition siding, wood shingles,
shakes, conventional stucco systems, plywood siding panels; and interior finish
systems that require a substrate panel with superior fire and moisture resistance.
For EIFS applications, DensGlass Sheathing is an ideal substrate for adhesive or
mechanical application of expanded polystyrene or extruded polystyrene insulation,
and is recommended in all climate zones.
Manufacturers of water and air resistive barriers, which include attached flexible
membranes, self-adhered membrane and liquid applied, have found DensGlass
Sheathing to be a suitable substrate for their systems.
DensGlass Sheathing is an ideal product for exterior ceilings and soffits for both
cold and warm climate zones. It resists sagging, even under exceptionally humid
conditions. Panels are applied directly to structural framing. Surface and joints
may be finished and painted, or surfaced with an exterior finish system.
Limitations
DensGlass Sheathing is resistant to normal weather conditions, but it is not intended
for immersion in water. Cascading roof/floor water should be directed away from
the sheathing until appropriate drainage is installed.
Avoid any condition that will create moisture in the air and condensation on
DensGlass Sheathing. The use of forced air heaters creates volumes of water
vapor which, when not properly vented, can condense on building materials.
The use of these heaters and any resulting damage is not the responsibility of
Georgia-Pacific Gypsum. Consult heater manufacturer for proper use and ventilation.
When DensGlass Sheathing panels are used in slanted wall applications, that portion
of the wall must be temporarily protected from the elements. Do not allow water
to pond or settle on sheathing. Also, exposed wall ends must be covered to
prevent water from infiltrating the cavity.
Georgia-Pacific Gypsum does not warrant and is not responsible or liable for the
performance of the cladding or exterior systems applied over DensGlass Sheathing.
The suitability and compatibility of any system is the responsibility of the system
manufacturer or design authority.
Do not laminate masonry surfaces to DensGlass Sheathing; use furring strips or
framing.
DensGlass Sheathing is not intended for roof applications. For roof applications,
consult our DensDeck
®
Roof Board brochure.
DensGlass Sheathing is not intended for interior or exterior tile applications. For
interior tile applications, consult our DensShield
®
Tile Backer brochure.
DensGlass Sheathing should not be used in lieu of plywood where required.
Do not apply DensGlass Sheathing below grade.
For all installations, design details such as fasteners, sealants and control joints
per system specifications must be properly installed. Openings and penetrations
must be properly flashed and sealed. Failure to do so will void the warranty.
Do not use DensGlass Sheathing as a base for nailing or mechanical fastening.
Fasteners should be flush to the face of the board, not countersunk.
Technical Data
DensGlass Sheathing is noncombustible as described and tested in accordance
with ASTM E136 or CAN/ULC S114.
DensGlass Sheathing exceeds ASTM C1396 sheathing standards for humidified
deflection by a factor of 10 in tests over the standard for regular gypsum sheathing.
