Product and Test Data


A fascia panel of thin reinforced stone supported by extruded aluminum perimeter frames and stiffeners and attached to substrates with interlocking clips and anchors.

TYPE OF STONE:  Many varieties of Granite, Marble, or Limestone are available in the thin reinforced format.

STONE VENEER THICKNESS: Calibrated to 3/8" (9.5mm) with a tolerance of + or - 1/32" (0.7mm).

STONE VENEER REINFORCING:  High strength glass fiber nettings are bonded to the stone veneer and encapsulated with epoxy in a vacuum formed impregnation.

DIMENSIONS:  Panels available in full slab sizes normally about 4'x8" and in some materials up to 5'x10".

TS100 PANEL THICKNESS:  Stone veneer plus aluminum frame equals 1 3/8".  Allow additional 5/8" (narrow) or 1" (wide) for attachment hardware.

WEIGHT:  Approximately 6 psf for stone and aluminum frames.

FINISHES:  Polished, honed, or flamed (granite only).

ABSORPTION:  ASTM C97 - 0.19% by weight (measurement of reinforced stone sample of Multicolor granite).

BULK SPECIFIC GRAVITY:  ASTM C97 - 2.74 (measurement of reinforced stone sample of Multicolor granite).

FLEXURAL STRENGTH:  ASTM C880 - (measurement of reinforced stone sample of Multicolor granite):

Positive pressure 9.045 psi
Negative pressure 2.417 psi

COMPRESSIVE STRENGTH:  ASTM C170 - 50,000 psi (sample of reinforced stone Multicolor granite tested to test machine limit).

FLAMMABILITY:  Thin reinforced granite panels have been tested in accordance with the ASTM E84 (Tunnel Test) results of:

Flame Spread 0
Smoke Developed 0

TOXICITY:  University of Pittsburg Protocol in accordance with New York City Building Code requirements:

Result: No more toxic than wood Accepted

BOND INTEGRITY:  Samples of thin reinforced granite have been tested in accordance with ASTM C297 Flatwise Tension which simulates resistance to delamination with the following results:

Resistance to vertical pull 553 psi

Tests were conducted before and after freeze-thaw with no significant difference in results. In fact, it was not possible to separate the mesh backing from the stone veneer in these pull-apart tests and all tests resulted in cohesive failure within the stone rather than separation between stone and reinforcing.

WINDLOAD - DEFLECTION:  A full scale mock-up of a thin reinforced stone faced panel with aluminum framing has been subjected to the following tests:
ASTM E330 Wind Pressure Passed
ASTM E331 Water Penetration Passed
ASTM E283 Air Infiltration Passed

The allowable deflection of the TS panel is L/200. The stuctural aluminum framing of the TS100 panel is designed to support the deflection and windload requirements of various building codes.

MECHANICAL ATTACHMENT OF STONE:  When a mechanical connection between stone and structure is required, the stone veneer is attached to the structural aluminum framework by a special bridge connection clip to a stainless steel undercut type expansion bolt set in the back face of the stone panel thereby creating a positive mechanical connection between stone and structure.

STRUCTURAL SILICONE:  For more than 40 years, structural silicone has been used as sole attachment of large glazing panels on high rise curtain walls. Dow Corning has tested and approved its No. 795 Structural Silicone for use in the thin stone wall system and offers a 20 year adhesion warranty for the system. The degree of silicone adhesion used in the TS100 System is more conservative than the common practice of the glazing industry.

IMPACT RESISTANCE:  A test bag weighing 23 lbs. swinging in a pendulum action against a test panel generated an impact force of 442 ft-lbs. without damaging the panel.
