                                    FORM T-3

                                     GENERAL

ITEM 1.    GENERAL INFORMATION.

           (a) The Applicant is a corporation.

           (b) The Applicant was organized under the laws of the Commonwealth of
Pennsylvania.

ITEM 2.    SECURITIES ACT EXEMPTION APPLICABLE.

           The Applicant intends to commence a solicitation (the "Solicitation")
of acceptances of a proposed Fourth Amended Plan of Reorganization of Armstrong
World Industries, Inc. (the "Plan") of the Applicant and certain of its
subsidiaries as set forth in the Plan, pursuant to which the Applicant intends
to issue __% Senior Notes due 2013 (the "New Fixed-Rate 10-Year Notes"), ___%
Senior Notes due 2010 (the "New Fixed-Rate Seven-Year Notes") and Floating-Rate
Notes due 2008 (the "New Floating-Rate Notes" and, together with the New
Fixed-Rate 10-Year Notes and New Fixed-Rate Seven-Year Notes, the "New Notes").
The Chapter 11 cases of the Applicant and certain of its subsidiaries are
presently pending before the United States Bankruptcy Court for the District of
Delaware (the "Bankruptcy Court"). The New Fixed-Rate Seven-Year Notes will be
issued pursuant to the indenture to be qualified under this Form T-3 (the
"Indenture"). The New Fixed-Rate 10-Year Notes and New Floating-Rate Notes will
be issued pursuant to separate indentures to be qualified under separate Form
T-3's. A copy of the Disclosure Statement relating to the Plan (which includes
the Plan as Exhibit A thereto), which was approved by an order of the Bankruptcy
Court dated June 2, 2003, is attached hereto as Exhibit T3E.

           Under the Plan, on the date on which the Applicant consummates the
Plan (the "Effective Date"), or as soon as practicable thereafter, the holders
of Allowed Unsecured Claims other than Convenience Claims and Allowed Asbestos
Personal Injury Claims (each as defined in the Plan) will receive New Notes in
partial satisfaction of such claims. The New Fixed-Rate 10-Year Notes will be
due 10 years after the Effective Date; the New Fixed-Rate Seven-Year Notes will
be due seven years after the Effective Date; and the New Floating-Rate Notes
will be due five years after the Effective Date. The Applicant anticipates
initially issuing up to approximately $250,000,000 of New Fixed-Rate 10-Year
Notes, up to approximately $250,000,000 of New Fixed-Rate Seven-Year Notes and
up to approximately $275,000,000 of New Floating-Rate Notes.

           The Applicant believes that the issuance of the Notes is exempt from
the registration requirements of the Securities Act of 1933, as amended (the
"Securities Act"), and state securities and "blue sky" laws pursuant to Section
1145(a)(1) of Title 11 of the United States Code (the "Bankruptcy Code").
Generally, Section 1145(a)(1) of the Bankruptcy Code exempts the offer and sale
of securities under a bankruptcy plan of reorganization from registration under
the Securities Act and under equivalent state securities and "blue sky" laws if
the following requirements are satisfied: (1) the securities are issued by the
debtor (or an affiliate participating in a joint plan with the debtor or the
debtor's successor) under a plan of reorganization; (2) the recipients of the
securities hold a pre-petition or administrative claim against the debtor or an
interest in the debtor; and (3) the securities are issued entirely in exchange
for the recipient's claim against or interest in the debtor or are issued
"principally" in such exchange and "partly" for cash or property. The Applicant
believes that the offer of the Notes under the Solicitation and the exchange of
Notes under the Plan will satisfy the requirements of Section 1145(a)(1) of the
Bankruptcy Code and, therefore, such offer is exempt from the registration
requirements referred to above.

described in the Disclosure Statement, the Applicant's indirect corporate
