Georgia-Pacific Gypsum, the first manufacturer to offer
extended Weather Exposure Limited Warranties for fiberglass mat gypsum panels,
is now doubling the weather exposure limited warranty for its entire line of
DensArmor Plus interior panels from six months to 12 months. All of the
following Georgia-Pacific Gypsum fiberglass mat interior panels now offer a
12-month weather exposure limited warranty:
- DensArmor Plus High-Performance Interior Panels
- DensArmor Plus Abuse-Resistant Interior Panels
- DensArmor Plus Impact-Resistant Interior Panels
These interior products join Georgia-Pacific Gypsum’s
exterior products, its flagship DensGlass Sheathing and DensGlass Shaftliner,
in offering the industry-leading 12-month weather exposure limited warranty for
and Canadian markets.
According to Mike Clay, vice president, sales and marketing
for Georgia-Pacific Gypsum, the move to lengthen the weather exposure limited

the ongoing stellar performance of the products, which were first introduced in
Recently, the DensArmor Plus High-Performance
Interior Panels, along with DensShield Tile Backer, became the first
gypsum panel products to pass the industry’s most stringent mold resistance

Protection Agency’s ASTM D 6329 protocol, is three times longer and much more
rigorous than ASTM D 3273, the current industry standard.
In other company news, Georgia-Pacific Gypsum announced that
its assembly for retrofitting lightweight commercial roof decks based on its DensDeck Roof
Board product can
reduce sound penetration by more than 50 percent.
According to the results of acoustical performance tests
conducted in December 2009 by Architectural Testing Inc., the roof deck
assembly with remediation components received a STC rating of 54, vs. a rating
of 43 for the baseline assembly alone. This 11 decibel improvement equals a
reduction in sound penetration of more than 50 percent.
The DensDeck Roof Board-based lightweight commercial roofing sound
remediation assembly includes the following layered components, which were used
in the acoustical tests: 1-inch rigid mineral fiber board, 5/8-inch DensDeck Roof
Board, and 45-mil TPO roofing membrane.
The acoustical tests of the Georgia-Pacific remediation
assembly were conducted in accordance with four industry-standard testing
methodologies (ASTM E 90-09, ASTM E 413-04, ASTM E 1332-90 and ASTM E
22350-04). For more information, visit www.densdeck.com.
