                          Independent Auditors' Report

To the Profit Sharing Committee of the
   Triangle Pacific Corp. Non-Union Hourly
   Employees' 401(k) Plan:

We have audited the accompanying statements of net assets available for benefits
of the Triangle Pacific Corp. Non-Union Hourly Employees' 401(k) Plan as of
December 31, 2000 and 1999, 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 Triangle
Pacific Corp. Non-Union Hourly Employees' 401(k) Plan as of December 31, 2000
and 1999, 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.

(1)  General Information

     The Triangle Pacific Corp. Non-Union Hourly Employees' 401(k) Plan (the
     Plan) became effective on July 1, 1996. On July 22, 1998, Triangle Pacific
     Corp. was acquired by Armstrong World Industries, Inc. (a subsidiary of
     Armstrong Holdings, Inc.). The Board of Directors of Triangle Pacific Corp.
     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 hourly employees of Triangle Pacific Corp. (the Company)
          who are not members of a collective bargaining agreement who work at
          least 1,000 hours annually, with new participants required to be at
          least 21 years of age and employed by the Company at least one year.
          The Plan is administered by Bruce Hardwood Flooring, LLC, a subsidiary
          of Triangle Pacific Corp., and advised by the profit sharing Committee
          appointed by the Board of Directors of the Company. The Plan is
          subject to the provisions of the Department of Labor's Rules and
          Regulations for Reporting and Disclosure under the Employee Retirement
          Income Security Act of 1974 (ERISA).

     (b)  Contributions

          Participants are permitted to contribute up to 10% of their eligible
          compensation to the Plan, as defined by the Plan documents.
          Participants may elect to invest their contributions in any of the
          available investment funds offered by the Fidelity Management Trust
          Company, the Trustee. Participants are able to direct all
          contributions to their account in 10% increments to the investment
          funds offered by the Trustee. Participants are immediately fully
          vested in their voluntary contributions plus actual earnings thereon.

     (c)  Participant Accounts

          Each participant's account is credited with the participant's
          contribution and Plan earnings. The benefit to which a participant is
          entitled is the benefit that can be provided from the participant's
          account.

               relief under Chapter 11 of the U.S. Bankruptcy Code in

               reorganization process to achieve a resolution of its asbestos
               liability. Triangle Pacific Corp. was not included in the filing.
               As of December 19, 2000, the Plan was amended to eliminate the
               Armstrong Holdings, Inc. Common Stock fund as an investment
               option effective with contributions made on or after December 27,
               2000 and transfers processed on or after January 1, 2001.

               high-quality, short-term securities. These securities may
               include, but are not limited to, high-quality short-term U.S.
               dollar denominated money market securities, domestic and foreign
               issuers.

     (e)  Payment of Benefits

          On termination of service due to death, disability or retirement, a
          participant may elect to receive either a lump-sum distribution or a
          rollover into another investment. Any disbursement less than $3,500 is
          required to become distributed in a lump-sum payment. The timing of
          the lump-sum payment will be determined by the Plan administrator or
          disbursed within 30 days upon filing a notice with the Employee
          Benefits Department.

(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 2000 and 1999, all significant expenses were paid by the
          Company ($8,783 in 2000 and $10,000 in 1999, respectively).

     (d)  Payment of Benefits

          Benefits are recorded when distributed.

                           December 31, 2000 and 1999

     (e)  Rollover Contributions

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

     (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.

(4)  Units

Participant accounts are assigned investment fund units/shares. The net asset
value per unit/share by fund/account for the 2000 and 1999 calendar quarters
ended is as follows:

(6)  Tax Status of the Plan

     The Company has not yet received a determination letter from the Internal
     Revenue Service as of December 31, 2000. However, the Plan administrator
     and the Plan's management believe that the Plan is designed and is
     currently being operated in compliance with the applicable requirements of
     the Internal Revenue Code.

(7)  Plan Termination

     Although it has not expressed intent to do so, the Plan administrator has
     the right to terminate the Plan at any time, subject to the provisions of
     ERISA.

(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. Triangle
     Pacific Corp. 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 and funds qualify as
     party-in-interest transactions.

(9)  Subsequent Events

     Effective April 2, 2001, the Plan document was amended to decrease the
     eligible participation age from 21 to 18 years old.
