| I believe there is a UV coated glass avaliable but as I remember the cost is rather steep. As long as the map isnt exposed to direct sunlight you should be ok with regular glass although when it comes to protecting a valuable document the best you can afford is a prudent investment,and the UV blocking coating,etc. IS extra protection. You might try a Framing shop and see if they either stock the coated glass/shatter resistant glass or know how to go about either obtaining it or even having your piece of glass coated. It is common for telescope owners to periodically send lens and mirrors assemblies or just the components out to be recoated so perhaps if you know any amature astronomers or can contact a local club they might be able to point you in the right direction. Good luck and let us know what you find out! Tom
