Specifications for glazing

Clara Deck inquires about laminated glass, noting that in a proposed
renovation program at the Henry Ford Museum they have been able to
find only one supplier and are expecting to pay a premium.

I am surprised. Perhaps you have very specific requirements. Or
perhaps your contractor/architect just isn't digging deep enough. I
pulled out of my files two manufacturers that would seem to meet
your needs:

    Pilkington LOF
    Their Supergray High Performance Tinted Float Glass has UV
    transmittance of 1%, a shading coefficient of 0.17, and (since
    insulation may be an issue in your part of the world), a U-value
    of 0.33. They can be reached at 419-247-4721.

    PPG
    <URL:http://www.ppgglass.com>
    Their Optigray 23 or Sungate 100 has UV transmittance of 2%, a
    shading coefficient of 0.21, and a U-value of 0.29. They can be
    reached at 800-377-5267 .

In addition, I would suggest that you call the North America
Laminated Glass Info Center<URL:http://lgic.glass-info.com/> at
800-230-4527. They can provide a large amount of research on
laminated glass and its longevity, as well as suppliers for specific
needs.

Hope this is helpful in your renovation project. Best,
