There are a couple of Technical Notes ('Selecting Exhibit Case
Glazing' and 'Security Glazing for Exhibits') in the National Park
Service's 'Exhibition Conservation Guidelines' CD-ROM that discuss
laminated glass and acrylic glazing with security and UV filtering
features.  If you e-mail me your Fax: number, I'll send you copies.
The TechNotes also list some products and suppliers. You
specifically mentioned glass laminate, so here are a few companies
to contact:

UV absorbing glass products:

1.  Product: Butacite

    Description: Butacite is laminated glass sheet with UV control
    from a PVB interlayer; viscoelastic properties provide dampening
    effect on noise; maintains color and clarity. The PVB inner
    layer adheres broken glass eliminating danger from loose shards.

    E.L.Du Pont de nemours & Co., Inc.
    Architectural Products
    1007 Market Street
    Wilmington, DE 19898

2.  Product: Tru Vue Conservation Series

    Description: Conservation Series is a UV filtering glass, clear
    or reflection control versions. MuseumGlass is an
    optically-coated, reflection-free product which increases the
    transmission of light through the glass.

Companies supplying Security Glazing - laminated glass panels

    1.  Monsanto

    2.  Dupont

    3.  Viracon Inc.
    800 Park Drive, PO Box 1400
    Owatonna, MS 55060

    4.  Northwest Industries Guardian Laminated Glass Corp.
    375 E. Church Ave.
    Telford, PA 18969-1003

Additionally, I've been looking into safety films for glass cases
already in use and have been reading about something called
'Protekt' window safety film made by Madico, Inc. in Woburn, MA,
617-935-7850. They have a number of film thicknesses to protect
against different levels of impact. The films also have other
features including UV filtering.
Hope this helps,
