We have windows within our facility that should have been covered, but weren't, and have some currently installed films that don't filter out as much UV as we'd like. Has anyone recently worked with a film manufacturer, and found someone that can provide a roll stock material that works for them in a glass application, and something they're happy with? The couple of places I've contacted so far are more into architectural films, so they're all over the variety of colors, but when I broach the subject of wavelength filtering to remove UV, it seems that's a "mad scientist" request.<o:p></o:p></p></div><div><p class=MsoNormal><o:p> </o:p></p></div><div><p class=MsoNormal>Thank you,<o:p></o:p></p></div><div><p class=MsoNormal><o:p> </o:p></p></div><div><div><div><div><p class=MsoNormal>Dennis Schweiger<o:p></o:p></p></div><div><p class=MsoNormal>Facilities Manager<o:p></o:p></p></div><div><p class=MsoNormal>University of Michigan/LNF<o:p></o:p></p></div><div><p class=MsoNormal>1301 Beal<o:p></o:p></p></div><div><p class=MsoNormal>Ann Arbor, MI 48109<o:p></o:p></p></div><div><p class=MsoNormal> <o:p></o:p></p></div><div><p class=MsoNormal>734.647.2055 Ofc<o:p></o:p></p></div></div></div></div></div></div></body></html>
