  • 1.  UV film

    Posted 06-13-2023 08:37

    Related to Madelyn's question and hopefully piggy-backing on the same audience...I had a collections manager relay to me a concern that UV film should not be applied to double-pane glass because of the danger of heat build-up and subsequent shattering of the glass. This is not something I have ever heard of before. Does anyone have any experience with this? Can you confirm or deny? 

    (In my experience, UV film actually reduces heat transfer through glass, but I'd love to hear from others.)

    Thanks,

    Nicole

    Hi Nicole,

    Thanks for your question. I have also never heard of this phenomenon/issue with the application of UV-filtering film on double paned glass. Let me look into it a little further... I'll get back to you!

    Kind regards,

    Victoria

    Hi again,

    From what I gather, this is likely a myth. Some quick online searching has indicated that if the film is applied to the glass following the manufacturer's specifications, it is highly unlikely to be the sole cause of thermal breakage. Though I don't have strong evidence to support this, I do feel that there would be more published accounts or a body of evidence related to this problem if it was occurring in the heritage sector, as many institutions employ the use of UV film.

    Here is a link to a discussion about this topic on the ConsDistList from 2014:  https://cool.culturalheritage.org/byform/mailing-lists/cdl/2014/0709.html

    Best regards,
