	I hereby constitute and appoint each of Walter T. Gangl, Douglas S. Brossman and
Robert J. Sandkuhler as my true and lawful attorneys-in-fact and agents, and grant each of them,
acting alone, full power to act on my behalf and in my name, place and stead, in any and all
capacities for the purpose of signing on my behalf, any Form 3, Form 4 or Form 5 required to be
filed by me pursuant to Section 16 of the Securities and Exchange Act of 1934, as amended, and
any Form 144 required to be filed by me under the Securities Act of 1933, as amended, and Rule
144 promulgated thereunder including, without limitation, the power to sign any and all
amendments to such forms, if any, and to file such forms with the Securities and Exchange
Commission, and to do and perform each and every act and thing requisite or necessary to be
done in connection with such forms, as fully and to all intents and purposes as I might or could
do in person.  The authority under this Power of Attorney shall continue until I am no longer
required to file Form 3, Form 4, Form 5 and Form 144 with regard to my ownership of or
transactions in securities of Armstrong World Industries, Inc. and Armstrong Holdings, Inc.,
unless earlier revoked in writing.

      I acknowledge that the above-named attorneys-in-fact are not assuming any of my
