Cavity Wall Applications
GlasRoc® Sheathing
is manufactured without starches, sugars, paper facing or pulp – and
it resists mold and mildew growth when tested in accordance
with ASTM D 3273.
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 weather resistive barrier is not
required by local codes), the joints should be treated with
a quality contractor's sheathing tape or exterior caulk (3M® Brand
Y-8086 Contractor Sheathing Tape or Dow Corning® 795
Silicone Building Sealant). Consult with authority having jurisdiction,
prior to installation.
Installation Recommendations
When installing a brick or stone
veneer over GlasRoc® Sheathing,
attach the brick or masonry ties through the GlasRoc® Sheathing
to the structural framing supports. Consult the manufacturer
or local building code authority for proper spacing and installation
of brick or masonry ties.
