HITACHI CHEMICAL CO., LTD. BEGINS SALES AND DELIVERY
OF WIDE-WIDTH SPD-SMART FILM FOR SMART WINDOWS
TO INNOVATIVE GLASS CORPORATION


Innovative Glass now producing architectural smart windows
with SPD film to fill existing orders.

TOKYO, JAPAN and PLAINVIEW, NEW YORK, February 1, 2007 -
Hitachi Chemical Co., Ltd. (Hitachi Chemical), and Innovative
Glass Corporation announced today that shipments of wide-width
SPD-Smart(tm) light-control film from Hitachi Chemical's newest
coating line have commenced. Innovative Glass has purchased and
received rolls of Hitachi Chemical's film and is now in
production of its EGLASS(tm) SPD-SmartGlass architectural products.


This marks the first time SPD-Smart film from Hitachi Chemical's
new wide-width coating line has been sold and delivered for
architectural smart glass. The film electrically controls
the amount of light, glare and heat that passes through
windows, doors, skylights, interior partitions, light
pipes, glass blocks and other products, via manual or
automatic control. Long rolls of SPD-Smart light-control
film can easily be shipped from Hitachi Chemical's production
facilities in Ibaraki, Japan, to customer locations
across the world where it can be laminated locally
into smart glass or plastic products.

Hitachi Chemical and Innovative Glass Corporation are licensees
of Research Frontiers Incorporated (Nasdaq: REFR), the developer
and licensor of patented suspended particle device (SPD)
light-control technology.

Hitachi Chemical's film sold to Innovative Glass is over one meter
wide and is being used to fill a backlog of architectural orders
that Innovative Glass has for its EGLASS SPD-SmartGlass product
line. With a turn of a dial, users can control light coming through
EGLASS from optically transparent to blocking over 99% of visible
light, and it can be tuned to any level of tint in between.
All of this can be done instantly to increase comfort, preserve
views, and conserve energy. EGLASS products using SPD film also
block over 99% of harmful ultraviolet light, reduce noise
and increase security.

Steve Abadi, Chairman and CEO of Innovative Glass, noted:
"We have been working with Hitachi Chemical and Research Frontiers
collaboratively to meet the demanding needs of architects, developers
and consumers for state-of-the-art light control. Hitachi Chemical's
responsiveness and determination to increase their production
capacity and supply a durable, high-quality film in wide widths
and high volume addresses the recent increase in demand for
energy-efficient, "green" building materials and innovative
designs, along with the broad trend towards the use of more
glass in homes, buildings and automobiles. Although we had
received early film samples from Hitachi Chemical's pilot
coating line, the first rolls of SPD-Smart film from
Hitachi Chemical's high-capacity coating line have now
been delivered to us for use in various construction projects.
This new wide-width film has the widest range of light
transmission and fastest switching speed when compared
to other technologies we have evaluated. The clarity and
dynamic range is outstanding, and our clients are eager to
experience the power, control, and other benefits of
SPD-SmartGlass. We are convinced that this is the
glass of the future, and our customers agree."


The SPD variable-tint technology permits the electrical
control of the amount of light passing through glass or
plastic windows, sunroofs, sunvisors, and other "smart"
products in the architectural, automotive, aircraft
and marine markets. By simply controlling the voltage
applied to the patented SPD film, the user can
automatically or manually control the amount of light
that passes through the device. Unlike conventional
shading technology, SPD technology permits the user
to control light, heat and glare and block UV without
blocking one's view. Its dark state permits less than
1% of visible light to pass through, a level that far
surpasses published data on any other switchable material.

Further distinguishing itself from other switchable
glazing technologies, SPD technology also responds
rapidly and uniformly over large surface areas,
consistently regardless of panel size, and with a
wide range of light transmission.

The film is made using a chemical emulsion manufactured
by Hitachi Chemical and coated onto a thin plastic film.
This film is then incorporated into a variety of "smart"
products manufactured by other companies where variable
light control is desired.
