           BRUNSWICK TECHNOLOGIES FILES COMPLAINT AGAINST SAINT-GOBAIN
                  AND AFFILIATES ALLEGING UNLAWFUL TENDER OFFER

         BRUNSWICK, MAINE, APRIL 27, 2000, Brunswick Technologies, Inc. (Nasdaq:
BTIC) ("BTI") announced today that it filed suit in federal district court in
Portland, Maine seeking injunctive and other relief against CertainTeed
Corporation, a wholly owned subsidiary of Compagnie de Saint Gobain (Paris,
France) and related affiliates in connection with CertainTeed's April 20, 2000
tender offer for all of the outstanding common shares of BTI not already owned
by its subsidiary, Vetrotex CertainTeed Corporation.

         In the action, BTI has alleged that CertainTeed and its affiliates, the
owner of approximately 14% of the outstanding common shares of and a major
supplier to BTI, violated Sections 13(d) and 14(d) of the Securities Exchange
Act by failing to make timely amendments to its Schedule 13D disclosing its
intent to acquire control of BTI, and by failing to comply with SEC requirements
concerning the delivery to BTI of its tender offer materials. In addition, BTI's
5 Count Complaint alleges that the actions of CertainTeed and its affiliates
have violated Maine state law.

         As part of the relief requested, BTI has asked in the best interests of
all BTI shareholders that the federal district court enter an interim order
temporarily halting CertainTeed's tender offer for 30 days, so that BTI's Board
of Directors can undertake a reasoned and expeditious evaluation of the terms
and conditions of the tender offer and make a recommendation to its
shareholders.

         Examples of products manufactured with BTI engineered reinforcements
include: ballistic armor, boats, snowboards, railcars, truck panels, wind
blades, airframe structures, automotive parts, marine pilings, bridges, and
offshore oil and gas production equipment. BTI has manufacturing facilities in
the Maine, Texas and the UK.

"estimate", "project", "plans", "believe", and similar expressions) that involve
known and unknown risks and uncertainties. For these statements the company
claims the protection of the safe harbor of the private Securities Litigation
Reform Act of 1995. The company's results may differ significantly from the
results indicated by such forward-looking statements. The Company's future

customers' capital spending plans and the ability of the company to obtain
necessary capital from time to time. These and other risks are detailed from
time to time in the Company's SEC reports, including Form 10K for the year ended
