I was thinking only of the effect of UV on the case, but I think you're talking about the effects of sun on the environment the piano is in, as well as on the piano itself. How about if the piano is in a room which is being hit by direct sun every day, but is not directly in sunlight? Other than tuning, which certainly is affected by directed heat from light, do you still see the problems you're describing, and how do you separate the effects of sunshine from those of an unstable environment?

The piano's glue joints are compromised, as are the tuning pin tightness. Also, actions can get real loosy-goosy as the variances in temp and humidity effects that too. Tuning, most certainly suffers. Any other questions? Joe Joe Garrett, R.P.T.

Ive never noticed anything other than cosmetic damage from UV exposure (granted, it can be pretty ugly). Pianos dont get cancer, do they? :-) Kerry Kean www.ohiopianotuner.com <http://www.ohiopianotuner.com/> _____ From: Joseph Garrett [mailto:joegarrett at earthlink.net] Sent: Monday, August 10, 2009 7:31 PM To: pianotech Subject: [pianotech] Sun Protection All, I've read the specs on the "UV Filters" for windows. That stuff only stops a small percentage of the UV/IR rays. For pianos you need to stop ALL the Sun on the piano, ALL the time. (PERIOD)!! Anything less and you are shortening the piano's life greatly. Of course this opinion is based on thefact that I had a client that refused to move a piano I had completely rebuilt. Within 5-6 years the piano was toast! He traded it in on a Steinway!![G] Probably has traded that in by now. He blamed all of the piano's problems on my work and that of the refinisher. I told him to take a hike! Haven't seen him since. Good riddance, IMNSHO! Most of my clients who have a sun problem have been able to solve the situation with vertical blinds or high-end curtain systems. Most 'modern' homes are not designed with pianos in mind, so the problem is previlant! (More like rampant!!) It is solveable. For situations, where there is just partial daily sunlight, I suggest Asian style free-standing screens. This seems to satisfy a lot of the Interior Design freaks.<G> Regards, Joe Joe Garrett, R.P.T.
