GlasRoc® Shaftliner is designed and engineered for use in constructing lightweight Shaftwall and Area Separation Firewall assemblies. GlasRoc® Shaftliner is UL Classified and ULC Listed in fire resistance designs and features double beveled edges for easy installation.

In addition to its fire resistive properties, GlasRoc® Shaftliner is also designed and engineered to provide added protection against mold. When tested for mold resistance by an independent lab, GlasRoc® Shaftliner achieved the highest possible score of 10 per ASTM D 3273, “Standard Test Method for Resistance to Growth of Mold on the Surface of Interior Coatings in an Environmental Chamber.

Installation of GlasRoc® Shaftliner boards should be consistent with methods described in the standards and references noted. GlasRoc® Shaftliner should be installed with the labeled side facing the weather exposure during construction.

CertainTeed is committed to resource conservation:

• The face and back paper used for our gypsum board consists of 100% recycled paper.
• Synthetic or “by-product” or DSG gypsum produced from the desulphurization of flue gases at coal-fired power plants is used where sourcesare available. Currently three manufacturing plants—Carrollton, Kentucky, Moundsville, West Virginia and Toronto, Ontario—use 100% synthetic gypsum.
• The total recycled content for these synthetic gypsum plants is 96%.
• In-plant scrap is recycled back into the process.; Our 14 gypsum board manufacturing locations provide regional material coverage throughout North America.
• Although LEED rating systems do not currently address emissions for all building materials and their effects on indoor air quality, finished CertainTeed gypsum board products have no reportable VOCs and will not affect indoor air quality.
