Integrated fiberglass solutions help OEMs reduce cost of energy generated by
on- and off-shore wind turbines

PARIS, March 12, 2014

PARIS, March 12, 2014 /PRNewswire/ -- Owens Corning (NYSE: OC), a leading
global producer of glass fiber reinforcements for composite systems, today
introduced an enhanced WindStrand^® Type 30^® roving products platform for
weaving fabrics at the JEC Europe show and conferences. This new product range
is designed to deliver productivity and performance benefits to OEMs
constructing and operating wind turbines in challenging on- and off-shore
locations with differing wind speed conditions.

In combination with this redefined wind product platform, Owens Corning also
unveiled its next-generation Ultrablade^® G3 unidirectional and new
Ultrablade^® Triax fabric solutions for specific wind turbine rotor blade
applications.

"The primary objective of turbine OEMs is to reduce total energy production
cost to align wind power with other energy sources," says Dr. Christopher
Skinner, Director of Product Platforms for Owens Corning's Composite Solutions
Business. "To help achieve a reduction in the cost of energy, future wind
turbines need to be manufactured as economically as possible while generating
as much power as possible. Our new range of WindStrand^® and Ultrablade^®
products deliver enhanced performance to address these needs."

The new product range comprises WindStrand^® 2000, WindStrand^® 3000, and
WindStrand^®4000 Type 30^® rovings  all of which provide high weaving
efficiencies for fabrics with optimized performance at 90 degrees (T). Each
product is designed to perform at differing higher fiber volume fraction
(FVF*) levels. The new WindStrand^® products deliver lower resin consumption,
contributing to an overall blade weight reduction of between 2 and 6 percent,
depending on the specific application and roving utilized.

The new Ultrablade^® G3 unidirectional (UD) fabric offers a high modulus and
excellent 90-degree(T) performance, and up to 20 percent greater resistance
to long-term fatigue loads. Its architecture can be customized to specific
end-use applications to meet market requirements for longer blades both
on-shore and off-shore, and in low-wind areas. Ultrablade^® G3 fabric displays
excellent mechanical properties when used in UD spar cap application. It can
also help reduce overall blade mass by up to 5 percent. Combined with an
operating FVF level of more than 57 percent, Ultrablade^® G3 UD fabric can
help increase blade lengths by up to 20 percent for turbines operating in
low-wind, on-shore areas.

The patent-pending optimal construction of the new Ultrablade^® Triax fabric
increases blade root laminate stiffness and strength providing a reduction of
up to 17 percent of the load transferred to rotor blade root bolts, thereby
substantially improving bolt fatigue life.

"Our new WindStrand^® and Ultrablade^® offerings provide weight-saving,
tailored solutions that are helping designers and engineers conceive blades
that are lighter and longer. And they deliver improved aerodynamic performance
with resistance to higher, long-term fatigue loads," Dr. Skinner added. "These
features enable the production of wind turbines that increase power yield and
reduce the cost of energy."

The announcements were made today at JEC Europe, the world's largest annual
composites trade show held in Paris, France, where Owens Corning is exhibiting
in Hall 7-2 Booth F22.
