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.

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

intrusion (when a separate water-resistive

barrier is not required by local codes),

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

manufactured to meet or exceed the

physical property requirements outlined in

ASTMC1177.

Installation Recommendation

Inaconventionalstuccosystem,metallath

should be attached to the framing

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.
