     KNOW  ALL MEN BY  THESE  PRESENTS  that  the  undersigned  constitutes  and
appoints  Mark A. Fuchs and Karen S.  Austin,  and  either of them,  my true and
lawful  attorneys-in-fact  and  agents,  with  full  power of  substitution  and
resubstitution  for me and in my name, place and stead in any and all capacities

the same,  with any or all other  documents in  connection  therewith,  with the
Securities and Exchange Commission, granting unto each said attorney-in-fact and
agent full power and  authority  to do and perform  each and every act and thing
requisite  and  necessary to be done,  as fully to all intents and purposes as I

attorney-in-fact  and agent or his or her substitute or substitutes may lawfully
do or cause to be done by virtue hereof.

     The authority granted to Mark A. Fuchs and Karen S. Austin under this power
of attorney shall continue until I am no longer  required to file Forms 3, 4 and
5  with  regard  to  my  ownership  of  or   transactions   in   securities   of
Louisiana-Pacific  Corporation,  unless  earlier  revoked in  writing.  I hereby
revoke all prior Powers of Attorney  appointing Anton C. Kirchhof as my true and
lawful attorney-in-fact.
