TOLEDO, Ohio - Pre-Filled Non-Woven Glass Veil Reduces Plastisol Use by up to 30
percent, Improves Production Efficiencies and Provides Smoother Surfaces

Global composite solutions and building materials leader Owens Corning
(NYSE: OC) today announced the development of AdVeil(TM) non-woven glass veil
incorporating a new technology that brings cost and production benefits to
the cushion vinyl (CV) flooring industry. Based on the company’s patented
Advantex(R) glass technology, AdVeil glass veil is supplied pre-filled with a
proprietary inorganic formulation that reduces plastisol use up to 150 grams
per square meter - a savings of up to 30 percent compared to conventional
non-woven glass veil offered in the marketplace. Other attributes of the
product, which will initially be available in Europe, include:

- The same thickness as standard veil, but a weight of 180
grams vs. 40 grams, making it less sensitive to creasing in the
manufacturing process
- An improved smooth-surface base for the design layer,
significantly reducing the risk of printing defects and improving design
quality
- Mechanical and dimensional stability
- High thermal stability

“AdVeil glass veil not only provides cushion vinyl flooring manufacturers
with a product that helps reduce raw material use and costs with only minor
production modifications, it also allows them to deliver an enhanced product
to their customers that improves their production efficiencies and end
product,” said Jean-Jacques Michat, Western Europe flooring sales leader,
OCV(TM) Non-Woven Technologies.

Underpinning the commercial and production advantages of AdVeil glass
veil is its environmental profile, which fits with the increasingly tough
demands from the flooring industry and consumers. AdVeil glass veil is
manufactured with Advantex glass fibers, which are produced using Advantex
glass furnace technology in a boron-free process, which when compared to
traditional E-glass manufacturing technology results in up to a 90 percent
reduction in fluoride emissions, more than 85 percent reduction in
particulate emissions, and more than 65 percent reduction in nitrogen oxide
emissions. Advantex technology is more energy efficient than traditional
E-glass, resulting less demand for fossil fuels and lower carbon dioxide
emissions.
