Dear Mr. English:
I appreciate very much your July 28 response to my inquiry regarding the long life quality of UF-3 Plexiglas.
We shall take your findings into consideration as we review the use of l/8 Plexiglas in the Irwin Miller residence.
Best wishes.

Dear Mr. Hungerford:
This will acknowledge the receipt of your letter to Mr. Feidler. Mr. Feidler retired last year, so I am responding on his behalf.
At the time we purchased the UF-3 Plexiglas, we were assured by the Manufacturer there should be no decrease in the effectiveness in screening out the ultraviolet radiation with age. Several years ago we had tests made on 1/8?? thick UF-3 material which had been exposed for four years, (inside under our skylights), and found very little light below 400 millimicrons, the higher wavelengths of ultraviolet, was being transmitted. This was no more than when the Plexiglas was new. We were pleased with the results of the tests and are debating having additional tests made.
The way we have installed the Plexiglas here at the Gallery, below glass skylights, we believe 1/8' thickness gives sufficient protection.
Sincerely yours,
Joseph G. EnglishAdministrator

Dear Mr. Feidler:
Following your good letter to Mr. Irwin Miller in June, 1967, Mr. Miller installed 1/8 inch EJF-3 plexiglas in his residence skylights.
He is quite pleased and wonders whether he should increase the thickness or replace the UF-3 plexiglas. In other words from your experience at the Gallery, does the UF-3 continue to filter ultraviolet radiation indefinitely? Is 1/8 inch thickness all that is required to protect oil paintings from direct and indirect ultraviolet radiation from the sun?
We would like to know what additional experience you have had, if any, with UF-3 plexiglas;
Sincerely,
ODHungerford/raj
