     Brunswick Technologies, Inc., a Maine corporation (the "Company" hereby
amends and supplements its Solicitation/Recommendation Statement on Schedule
14D-9 dated May 3, 2000 (as amended by Amendments No. 1 through 8, the "Schedule
14D-9") relating to the tender offer by VA Acquisition Corporation, (the
"Purchaser") and a wholly-owned subsidiary of CertainTeed Corporation, a
Delaware Corporation (the "Parent") both of which are indirect wholly owned
subsidiaries of Compagnie de Saint-Gobain, a French corporation, to purchase
outstanding shares of common stock, par value $.0001 per share (the "Shares"),
of the Company at a price of $8.00 per share, net to the sellers in cash, upon
the terms and subject to the conditions set forth in the Offer to Purchase,
dated April 20, 2000 and in the related Letter of Transmittal as disclosed in
the Tender Offer Statement on Schedule 14D-1 dated April 20, 2000, as amended by
Amendments No. 1 through 17 to Schedule 14D-1. All capitalized terms shall have
the meanings assigned to them in the Schedule 14D-9, as amended to date, unless
otherwise indicated herein.

ITEM 8.    ADDITIONAL INFORMATION

     Item 8 is hereby amended by the addition of the following:

     On June 7, 2000, representatives of Saint-Gobain, Parent and the Company
met to commence serious negotiations regarding a possible consensual
transaction, during which meeting Parent indicated it was prepared to improve
the Offer by increasing the purchase price in exchange for a negotiated merger
agreement. Negotiations continued into the late evening of June 12, 2000, at
which time (1) a merger agreement was entered into between and among Parent,
Purchaser and the Company and (2) Parent and Purchaser agreed to increase the
purchase price in the Offer from $8.00 to $8.50 per Share, net to the seller in
cash, without interest. A copy of the merger agreement will be filed as an
Exhibit to the Schedule 14D-9 in a subsequent Amendment. In the merger
agreement, the Company has agreed to support Parent's improved Offer. The
Company also has agreed to redeem the preferred share purchase rights under the
Rights Agreement dated April 17, 2000 between the Company and State Street Bank
and Trust Company. Both Parent and the Company expect to supplement their
respective Schedules TO and 14D-9 to reflect details of the negotiated
transaction in further amendments to be filed shortly.

     On June 13, 2000, Parent issued a joint press release with the Company, in
which Parent announced the improved purchase price and the extension of the
Offer to 12:00 midnight, New York City time, on Thursday, June 29, 2000.
Accordingly, the term "Expiration Date" in the Parent's Offer means midnight,
New York City time, on Thursday, June 29, 2000, unless Parent, in its sole
discretion, extends the period of time for which the offering period of the
Offer is open, in which case the term "Expiration Date" will mean the time and
date at which the offering period of the Offer, as so extended, will expire. The
Offer had previously been scheduled to expire at 12:00 midnight, New York City
time, on Friday, June 16, 2000.

     A joint press release announcing the merger agreement, the improved Offer
and the extended Expiration Date was issued early on June 13, 2000, and a copy
is attached hereto as Exhibit 18 and is incorporated by reference.


ITEM 9.    MATERIAL TO BE FILED AS EXHIBITS

     Item 9 is hereby amended by the addition of the following:

     Exhibit 18    Joint Press Release dated June 13, 2000.

                                                                      Exhibit 18

                     CERTAINTEED AND BRUNSWICK TECHNOLOGIES
                        SIGN DEFINITIVE MERGER AGREEMENT


             CERTAINTEED TO ACQUIRE BTI FOR $8.50 PER SHARE IN CASH

Valley Forge, PA and Brunswick, ME, June 13, 2000 -- CertainTeed Corporation, a
wholly owned subsidiary of Compagnie de Saint-Gobain (Paris, France), and
Brunswick Technologies, Inc. (Nasdaq: BTIC) ("BTI") jointly announced today that
they have signed a definitive merger agreement under which CertainTeed will
acquire BTI for $8.50 per share in cash. Vetrotex CertainTeed Corporation,
CertainTeed's fiber glass reinforcements business, currently owns about 14% of
the outstanding shares of BTI.

Under the terms of the agreement, CertainTeed is increasing the price of its
pending tender offer to purchase all outstanding shares of BTI to $8.50 per
share in cash. BTI's Board of Directors has unanimously approved the tender
offer and the merger and recommends that BTI shareholders tender their shares.
Each BTI director has agreed to tender his shares. In addition, both parties
have agreed to dismiss any pending litigation relating to the tender offer, and
BTI's Board has waived its shareholder rights plan with respect to the
CertainTeed offer. CertainTeed and BTI have also agreed to postpone the June 16,
2000 special meeting of BTI shareholders until Friday, June 30, 2000.

Following the completion of the tender offer, CertainTeed intends to consummate
a second step merger in which all remaining BTI shareholders will also receive
the same cash price paid in the tender offer.

Roberto Caliari, President of the Reinforcements Division of Compagnie de
Saint-Gobain, stated, "We are very excited about our combination with BTI. We
believe that together we will be able to optimize and accelerate the development
of new products and new product applications. And because Saint-Gobain has a
strong fiber glass reinforcements business all over the world, BTI's products
will enjoy efficient access to new markets.

"We welcome BTI into our family, and we look forward to bringing these two
companies together and working with the talented employees of BTI," Mr. Caliari
continued. "In addition, both Saint-Gobain and BTI have solid histories of
community involvement and economic development, and we remain committed to
building on those traditions in Maine and all of the communities in which we
will operate."

"After thoroughly reviewing all of BTI's strategic alternatives, BTI's Board
concluded that a combination with Saint-Gobain provides BTI shareholders the
maximum current value for their shares, and significant opportunities for our
employees and customers," said Martin S. Grimnes, Chairman and Chief Executive
Officer of BTI. "Through this combination, BTI can leverage Saint-Gobain's
tremendous resources as we continue to develop advanced composite reinforcement
products for this rapidly expanding, global marketplace."

Upon completion of the transaction, BTI will become part of the Technical
Fabrics Group of Saint-Gobain's Reinforcements Division.

Pursuant to the merger agreement, CertainTeed is also extending its cash tender
offer until midnight, New York City time, on Thursday, June 29, 2000. As of 3
p.m. New York City time on June 12, 2000, approximately 250,160 of shares of BTI
common stock had been validly tendered and not withdrawn pursuant to the offer.
The tender offer was scheduled to expire at midnight, New York City time, on
June 16, 2000.

CertainTeed's tender offer will be amended to reflect the terms and conditions
contained in the merger agreement. As previously announced, the
Hart-Scott-Rodino waiting period applicable to the tender offer has expired.

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 Maine, Texas
and the UK.

CertainTeed Corporation is a leading manufacturer of roofing; vinyl and fiber
cement siding; vinyl windows; vinyl fencing, deck and railing; ventilation
products; piping products; fiber glass insulation; and fiber glass products for
reinforcing plastics and other materials. The company is headquartered in Valley
Forge, Pennsylvania, and has more than 7,000 employees and 45 manufacturing
facilities throughout the United States.
