GlasRoc® Sheathing is a high performance,
water resistant, gypsum-based exterior
sheathing.
GlasRoc Sheathing offers a patented
technology of a high performance polymer
coating on reinforcing glass mat facers.
This unique coating provides a superior
water and UV resistant surface for long term
protection to weather exposures.
The “paperless” glass mat facers are
embedded into a water resistant gypsum core,
and positioned beneath a polymer modified
gypsum surface.
GlasRoc Sheathing offers:
• Long term protection (12 months) to
weather exposure.
•Asuperiorwaterresistantsurfacethat
does not inhibit water vapor permeance.
•Excellentfireresistanceproperties,
and numerous fire rated designs.
•Moldresistance.
•Durability-resistsdelaminationdueto
embedded glass mat in the gypsum core.
• Strength – with enough flexibility to bend
to curved surfaces.
• Alightweightsheathingthatcutslike
regular gypsum board and is easy to handle
andinstall–withminimalskinirritationdue
to embedded glass mats.
•Conformity to design and code requirements.
GlasRoc Sheathing is the next generation
of the industry standard for high-performance,
weather-resistive, gypsum-based sheathing.

Superior Strength
GlasRoc® Sheathing integrally bonds its
polymer face coating to the moisture
resistant core, resulting in a superior
protective sheathing that will perform in all
climates.
Dimensional Stability
GlasRoc Sheathing resists delamination,
rippling,bucklingandsaggingcaused
by environmental conditions, such as
freeze/thaw,heatandhumidity,anddirect
UV exposure. This technology, with its
embeddedglassmats,makesGlasRoc
Sheathing state-of-the-art, and will provide

GlasRoc® Sheathing offers a protective,
smooth, water-resistant application
surface which will withstand water
penetration into the stud cavity, so a
separate weather-resistant barrier may
not be necessary, unless required by
local code. To best prevent air and water

GlasRoc® Sheathing’s integral coated
surface with its high surface bond
strength provides an excellent water-
resistant surface for conventional stucco
applications. The treated core adds to
the water-resistive performance of the
product. Conventional stucco systems
rely on the structural soundness of the
sheathing component to which they are
applied. GlasRoc Sheathing offers physical
properties superior to competitive gypsum
sheathingproductsinthemarket.Itis
manufactured to meet or exceed the
physical property requirements outlined in
ASTMC1177.
Installation Recommendation
Inaconventionalstuccosystem,metallath
or other specified self-furring components
should be attached to the framing
members through the GlasRoc Sheathing,
after the appropriate water-resistive barrier
and flashing is installed. Use appropriate
jointtreatmentasrequiredbylocalbuilding

by the manufacturer.

GlasRoc® Sheathing
Refer to finish system
manufacturer for glass mesh
reinforcement requirements.
GlasRoc® Sheathing is engineered for
use in curved exterior gypsum board
applications. There is no need to score or
moisten the board to bend it. To prevent
flat areas in the curved surface, framing
should be positioned at a maximum
spacingof6”(150mm).
ConsulttheGypsumAssociationdocument
GA-226forframingrecommendations.
Application to Archways
GlasRoc Sheathing can be installed in an
archway or on a concave or convex surface
by applying pressure onto the board to fit
the radius and then holding it firmly in place
while fastening it to the framing members.
To best seat the product in tight radius
applications, temporarily install a stop at
one end of the framed radius to serve as
arestraintsupport.Installtheproductwith
coated side out with one of the width ends
placed flush against the temporary stop
and secure with fasteners, one framing
member at a time. Repeat until the product
has been secured to all framing members.
