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:
Plus High-Performance Interior Panels
Plus Abuse-Resistant Interior Panels
Plus Impact-Resistant Interior Panels
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 the U.S. and Canadian markets.
to Mike Clay, vice president, sales and marketing for Georgia-Pacific Gypsum,
the move to lengthen the weather exposure limited warranty for the DensArmor
Plus Interior Panels line was based on the ongoing stellar
performance of the products, which were first introduced in 2002.
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 test. The 12-week test,
conducted in accordance with the U.S. Environmental Protection Agency’s ASTM D
6329 protocol, is three times longer and much more rigorous than ASTM D 3273, the
current industry standard.
12-month weather exposure limited warranty extension and the 12-week test
results continue the long history of “firsts” achieved by Georgia-Pacific
Gypsum via its Dens family of products, which were first introduced more than
20 years ago.
Georgia-Pacific Gypsum was the first company
to offer fiberglass mat products, the first to score a 10, the highest rating,
when tested, as manufactured, under ASTM D 3273 and the first to offer an
extended weather exposure limited warranty.
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.
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
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
The assembly is designed for buildings with low-slope roofs in the vicinity of
airports or other high-decibel environments. These include hotels, apartments,
nursing homes, assisted living facilities, schools and other low-rise
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).
