                       Independent Auditors' Report

To the Retirement Committee of the
   Hartco Flooring Company
   Retirement Savings Plan:

We have audited the accompanying statements of net assets available for benefits
of the Hartco Flooring Company Retirement Savings Plan as of December 31, 2001
and 2000, and the related statements of changes in net assets available for
benefits for the years then ended. These financial statements are the
responsibility of the Plan's management. Our responsibility is to express an
opinion on these financial statements based on our audits.

We conducted our audits in accordance with auditing standards generally accepted
in the United States of America. Those standards require that we plan and
perform the audit to obtain reasonable assurance about whether the financial
statements are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements. An audit also includes assessing the accounting principles used and
significant estimates made by management, as well as evaluating the overall
financial statement presentation. We believe that our audits provide a
reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the net assets available for benefits of the Hartco
Flooring Company Retirement Savings Plan as of December 31, 2001 and 2000, and
the changes in net assets available for benefits for the years then ended in
conformity with accounting principles generally accepted in the United States of
America.

Our audits were performed for the purpose of forming an opinion on the basic
financial statements taken as a whole. The supplemental schedule of assets held
for investment purposes is presented for the purpose of additional analysis and
is not a required part of the basic financial statements but is supplementary
information required by the Department of Labor's Rules and Regulations for
Reporting and Disclosure Under the Employee Retirement Income Security Act of
1974. The supplemental schedule has been subjected to the auditing procedures
applied in the audits of the basic financial statements and, in our opinion, is
fairly stated in all material respects in relation to the basic financial
statements taken as a whole.

                          Notes to Financial Statements
                           December 31, 2001 and 2000

(1)  General Information

     On June 28, 1996, Armstrong Wood Products, Inc. (the Company) (formerly
     known as Triangle Pacific Corp.) acquired from Premark International, Inc.
     (Premark) all of the common stock of Hartco Flooring Company. In connection
     with this acquisition, Premark and the Company agreed to spin off,
     effective as of June 28, 1996, that portion of the Premark Plan benefiting
     participants who were employees or former employees of Premark, to a
     separate plan sponsored and maintained by the Company to be known as the
     Hartco Flooring Company Retirement Savings Plan (the Plan), as set forth
     herein, as a continuation, without interruption, of such portion of the
     Premark Plan.

     On July 22, 1998, Armstrong Wood Products, Inc. was acquired by Armstrong
     World Industries, Inc. (a subsidiary of Armstrong Holdings, Inc.). The
     Board of Directors of Armstrong Wood Products, Inc. intends to continue
     providing retirement benefits through the Company's defined contribution
     plans.

(2)  Description of the Plan

     The following description of the Plan provides only general information.
     Participants should refer to the Plan document for more detailed
     information.

     (a)  General

          The Plan is a defined contribution plan which provides retirement
          benefits to employees of Hartco Flooring Company, a division of
          Armstrong Wood Products, Inc., who are not members of a collective
          bargaining agreement and whose customary employment is for at least
          1,000 hours during a 12-month period. Employees are eligible to
          participate in the Plan on the first day of the month coincident with
          or following the completion of six months of service. All eligible
          employees whose customary employment is not for at least 1,000 hours
          during a year participate in the plan on the first day of the month
          coincident with or following the 12-month period after their
          employment or any plan year thereafter, provided 1,000 hours of
          service are completed during this time period. However, employees must
          not be active participants in any other defined contribution plan to
          which the Company or any subsidiary contributes on their behalf.
          Effective November 1, 2001, the Plan was amended to allow for
          immediate participation by employees upon the completion of one hour

          Participants are fully vested in the current value of their own
          contributions and earnings thereon, and become fully vested in Company

          Elective contributions may be invested in guaranteed income funds,
          fixed income funds, equity funds, or a money market fund at the option
          of the participating employee. The Plan has investment options
          available to which participants may allocate their contributions as
          follows:

     (g)  Payment of Benefits

          On termination of service due to death, disability, or retirement, a
          participant may elect to receive the total value of their account
          attributable to their contributions, as well as the vested value of
          their Company contributions, in cash or by purchasing an annuity under
          the terms of an annuity contract. For termination of service due to
          other reasons, a participant may receive the value of the vested
          interest in his or her account as a lump-sum distribution.
          Participants may make hardship withdrawals from their earnings
          deferred contributions at specified times, subject to the
          determination by the Plan administrator that the withdrawal is
          required to meet an immediate and heavy financial need.

     (h)  Forfeitures

          Company contributions forfeited by terminating employees are used to
          reduce future Company contributions to the Plan ($19,654 and $6,708 in
          2001 and 2000, respectively). The Company will reinstate forfeited
          balances to the accounts of participants who rejoin the Company within
          five years of their termination.

(3)  Summary of Significant Accounting Policies

     (a)  Basis of Accounting

          The financial statements of the Plan are prepared under the accrual
          method of accounting.

     (b)  Investment Valuation and Income Recognition

          The Plan's investments are stated at fair value and have been
          determined based on closing market quotations. Purchases and sales of
          securities are recorded by the trustee at current cost on the trade
          date. Realized and unrealized gains (losses) on investments are based
          on the fair value of the assets at the beginning of the Plan year or
          at the time of purchase during the year. Interest income is recorded
          on the accrual basis. Dividends are recorded on the ex-dividend date.

     (c)  Administration Expenses

          In accordance with the provisions of the Plan, unless paid by the
          Company, all costs of administering the Plan are charged to the Plan.
          During 2001 and 2000, all significant expenses were paid by the
          Company ($8,544 in 2001 and $16,087 in 2000, respectively).

     (d)  Payment of Benefits

          Benefits are recorded when distributed.

     (e)  Rollover Contributions

          Employee rollovers represent receipts from employees receiving
          distributions from their previous employers' qualified plan(s).

                           December 31, 2001 and 2000

     (f)  Use of Estimates

          The preparation of financial statements in conformity with accounting
          principles generally accepted in the United States of America requires
          management to make estimates and assumptions that affect the reported
          amounts of assets, liabilities, and changes therein, and disclosure of
          contingent assets and liabilities. Actual results could differ from
          those estimates.

     (g)  New Accounting Pronouncements

          In June 1998, the Financial Accounting Standards Board issued SFAS No.
          133, Accounting for Derivative Instruments and Hedging Activities
          (SFAS No. 133). SFAS No. 133 requires that an entity recognize all
          derivatives in its statement of net assets and measure those
          instruments at fair value with changes recognized in the statement of
          changes in net assets.

          SFAS No. 133 is effective for fiscal years beginning after June 15,
          2000. Pursuant to SFAS No. 137, the Plan adopted SFAS No. 133
          effective January 1, 2001. The Adoption of SFAS No. 133 did not have a
          material impact on the Plan financial statements.

                           December 31, 2001 and 2000

(6)  Tax Status of the Plan

     The Internal Revenue Service has determined and informed the Company by a
     letter dated January 27, 1998, that the Plan and related trust are designed
     in accordance with applicable requirements of the Internal Revenue Code
     (IRC). The Plan has been amended since receiving the determination letter.
     However, the Plan administrator and Plan's management believe that the Plan
     is designed and is currently being operated in compliance with the
     applicable requirements of the IRC.

(7)  Plan Termination

     Although it has not expressed intent to do so, the Company has the right to
     discontinue its contribution at any time and to terminate the Plan subject
     to the provisions of ERISA. In the event of Plan termination, participants
     will become fully vested in their accounts.

(8)  Related-Party Transactions

     Certain Plan investments are shares of common stock of Armstrong Holdings,
     Inc. and shares of mutual funds managed by Fidelity Investments. Armstrong
     Wood Products, Inc. is a wholly owned subsidiary of Armstrong World
     Industries, Inc. Fidelity Management Trust Company is the trustee as
     defined by the Plan. Therefore, transactions involving these entities or
     funds qualify as party-in-interest transactions.

(9)  Subsequent Events

     In 2002, the Plan was amended due to changes in various legislation and
     governmental regulations. These amendments were compliance related and no
     changes were made to the design of the Plan.

     Subsequent to December 31, 2001, the date for valuation of plan assets
     provided herein, the value of plan investments has changed, and some have
     fallen significantly from their values shown here.
