New Owens Corning Duration(TM) Series Shingles With SureNail(R) Technology Help Reduce Redtags, Callbacks and Improve Cycle Time

Press release date: Feb 07, 2007

ORLANDO, Fla., Feb. 7 /-- Builders looking to capture additional efficiencies and buyer satisfaction should look to the rooftop. Owens Corning (NYSE:OC), the manufacturer of America's # 1 brand of roofing shingles*, introduces Duration(TM) Series shingles with SureNail(R) Technology. Due to the liberal nailing area, contractors report improved productivity and greater accuracy, allowing them to get on to their next roof sooner and reduce builder cycle times. Duration Series shingles also deliver greater wind protection -- resisting up to category three hurricane force winds. Owens Corning is the only maker of asphalt roofing shingles with this powerful combination of benefits.

-- Reduce callbacks: Installation errors can trigger inspection redtags on the job site. They also may cause leaks or tear-offs in high winds, producing a callback from the homeowner. Duration Shingles with SureNail Technology have a wider, reinforced nailing area and a clearly recognizable nailing strip that allows roofing subcontractors to install with greater accuracy.

-- Improve cycle time: Due to the liberal nailing area associated with the SureNail strip, roofing contractors have reported productivity gains, allowing them to move on to the next roof sooner. Roofs that go up fast with fewer mistakes reduce cycle time for builders.

-- Gives homebuyers peace of mind: The additional bonding strength provided by the interaction between the Tru-Bond(R) sealant and the SureNail nailing strip gives shingles with SureNail Technology extra high wind performance: 130 mph on Duration Premium shingles and 110 mph on Duration shingles. The industry standard is 70 mph and 90 mph respectively. That's a differentiator buyers will notice.

Duration Premium shingles feature a bold, vibrant, thick-looking pattern while Duration shingles provide a soft, muted pattern. Both are available in an extensive array of 12 colors. Duration Series shingles come with a class A UL fire rating, the highest in the industry, as well as a 10-year algae-resistance warranty**.

"Building codes have become more stringent for roofing due to the recent history of rough weather. By changing the way our shingle layers bond, Duration shingles carry a wind warranty equal to most severe-weather conditions," said Bert Elliott, Residential Roofing Shingles product manager for Owens Corning. "The additional benefits to builders are clear: the liberal nailing area gives builders confidence that the shingles are installed right."
