GreenGlass Fiberglass Gypsum Tile Backer

GreenGlass®

Fiberglass-Faced Gypsum Tile Backer Board

GreenGlass tile backer, a fiberglass-faced gypsum board, is a strong, water-resistant substrate for the application of tile in high-moisture, high-humidity commercial and residential environments. Superior for walls, ceilings, shower and tub enclosures, countertops and light flooring, GreenGlass tile backer features a built-in, moisture-blocking coating over naturally mold- and moisture-resistant fiberglass facers laminated to a specially formulated water-resistant core. GreenGlass tile backer also offers a standard-setting level of certified recycled gypsum content that can contribute toward credits in multiple green building rating systems.

Features:

  • TemShield Mold Protection System engineered into our gypsum core which is sandwiched between naturally mold-resistant fiberglass facers (GreenGlass scored a 10, the highest possible value, when tested in accordance with ASTM D3273, the standard test for mold resistance).
  • Built-in, moisture-blocking acrylic coating resists water penetration and eliminates the need for additional vapor retarder
  • Available in 1/4" (6.3 mm) and 1/2" (12.7mm) thicknesses as well as a fire-resistant 5/8" (15.9 mm) thickness
  • 5/8"-thick panels are U.L.classified for use in any fire-rated assembly requiring 5/8" Type X gypsum board
  • 1/2" (12.7mm) and 5/8" (15.9 mm) tile backer SCS certified to contain a minimum of 90% recycled gypsum content on a dry-weight basis
  • 1/4" (6.3 mm) tile backer SCS certified to contain a minimum of 85% recycled gypsum content on a dry-weight basis
  • Third-party certified to meet the performance standard for CHPS program low-emitting material recognition

Special Order Information:

Other widths, edges and lengths may be available on special order with established minimums and lead time. Some products may not be available in all markets. Please check with your local Temple-Inland sales representative.

Limitations:

  • For interior use only
  • Should not be used as a shower pan base or in shower floors or curbs
  • Avoid installation where prolonged exposure to temperatures exceeding 125° F (52° C) required
  • Should not be used as a base for nailing and mechanical fastening
  • Framing spacing should not exceed 16" (406 mm) o.c. without blocking or 24" (610 mm) o.c. with blocking
  • Do not apply directly to concrete or block; framing or furring required
  • Do not apply with construction adhesives alone; nails, screws or staples alone acceptable or combined with adhesive
  • Avoid installing vapor retarders directly behind GreenGlass in new construction or penetrate existing coverings that may act as a retarder in retrofit applications

Mold and Moisture Resistance:

Produced with the TemShield Mold Protection System engineered into its gypsum core, GreenGlass tile backer is faced on both sides with naturally mold-resistant fiberglass mats. It scored a 10, the highest value possible, when tested in accordance with ASTM D3273, the standard test for mold resistance.

In addition, the water-resistant core of GreenGlass combined with its acrylic surface coating is designed to dramatically reduce wicking and moisture pass-through compared to cementitious backer panels. Moisture is stopped at the surface to resist build up and damage within the wall cavity.

Fire Resistance:

Tested in accordance with ASTM E136, GreenGlass 5/8” (15.9 mm) Type X tile backer may provide a fire-resistance rating of 1 or more hours depending upon the assembly in which it is applied. Tile installation is not required to achieve the fire-resistance rating. GreenGlass is a U.L.-classified substrate and can replace a 5/8” (15.9 mm) Type X gypsum board in most fire-rated assemblies.

Low VOC-Emitting Material:

Temple-Inland gypsum board products are third-party certified by Materials Analytical Services, LLC (MAS) to meet the performance standard established for low-emitting materials under the Collaborative for High Performance Schools (CHPS) Program.

Sulfur Emissions Testing:

In emissions level testing for carbon disulfide and carbonyl sulfide conducted by Materials Analytical Services (MAS), Temple-Inland gypsum board was determined to be negative for sulfur off-gassing and is not considered a problematic corrosive drywall type.

Storage:

Gypsum board should be carried, never dragged, to prevent damaging the finished edges. When storing gypsum boards, store them indoors and protect them from weather and direct sunlight. Boards should be stored lying flat and neatly stacked. Care should be taken to prevent sagging or damage to edges, ends and surfaces. Placing boards against framing is not recommended.
