| A well-known fundamental property of laminated
glass is its high level of safety and security. In addition to fundamental
properties including the above, heat control is also required for
laminated glass recently to create more comfortable space, and for
environmental reasons. For example, laminated glass used in vehicles'
windshields needs to improve the efficiency of air conditioners for
further passenger amenity. Because relatively large amount of heat
is transmitted through a windshield, heat control has been required
for automotive glass. Meanwhile, in the environmental views, heat
control is effective to reduce fuel consumption because the car engine
is not overwhelmed if an air conditioner more efficiently cools in-car
space with glass that controls the temperature. Moreover it allows
cars to carry smaller and lighter air conditioners. Solar control
laminated glass can be used also for architectural uses to achieve
outcomes similar to the automotive uses mentioned above. |

| Conventional laminated glass with UV filtering
interlayer films screens 10% of harmful UV rays in sun light. However
considerable amount of heat energy transmits through the glass. Keeping
the existing functions of conventional interlayer films, SEKISUI's
Solar control interlayer film, Solar Control Film, screens large amount
of Infra Red rays (heat rays). |

| The difference between a conventional
interlayer film and our heat control interlayer film is obvious that
our heat control film effectively filters Infra Red rays as shown
in the transmission spectrum. In this spectrum, the solar control
interlayer film proves that it effectively shields heat transmission,
better than heat absorbing glass like green glass. |
