                                                                    EXHIBIT 99.1

           Trex Company 2004 Third Quarter Revenue Up 56%;
   EPS Up 37%; Product Introductions Offer Exciting New Options for
               Consumers to 'Create Your Space' in 2005

    WINCHESTER, Va.--(BUSINESS WIRE)--Oct. 25, 2004--Trex Company,
Inc. (NYSE:TWP), manufacturer of Trex(R) decking and railing, today
announced financial results for the third quarter ended September 30,
2004.
    Net sales for the 2004 third quarter totaled $64.4 million
compared to $41.2 million for the 2003 third quarter. Net income for
the 2004 third quarter totaled $7.1 million, or $0.48 per diluted
share, compared to $5.1 million, or $0.35 per diluted share, for the
2003 third quarter.
    For the nine months ended September 30, 2004, Trex Company
reported net sales of $224.0 million compared to $169.1 million for
the 2003 nine month period. Net income for the nine months ended
September 30, 2004 totaled $27.5 million, or $1.86 per diluted share,
compared to $21.8 million, or $1.48 per diluted share, for the 2003
nine-month period.
    Chairman and Chief Executive Officer Robert Matheny commented,
"Trex Company continued to grow its business in the third quarter as
more and more consumers learned about the many benefits of composite
decking and responded enthusiastically to our expanding array of
products and styles. Our Trex Accents(TM) line, which features wood
grain texture, has become an important part of our product line-up in
a very short period of time. Demand for our Trex Designer Series
Railing(TM), a line of high-style railing components that match our
deck boards, has also been growing steadily. We are also encouraged by
our Home Depot experience to date. Results have met our expectations
and the general market awareness the Home Depot program creates for
Trex is growing independent dealer volume as well. However, while our
sales and profits were up significantly over last year, higher
manufacturing costs, especially the price of raw materials, did
adversely affect our gross margin in the quarter.
    "As we move toward 2005, I am very excited by the innovative
products Trex will bring to market in the coming year, all of which
are designed to give consumers more freedom to build the deck of their
dreams. Beginning next year, we will introduce Trex Exotics(TM) deck
boards, trim profiles and railings which will offer the distinctive
look of tropical hardwoods without the high installation cost or
maintenance requirements associated with tropical hardwoods. Through a
special process, subtle shadings and natural color variations create
the rich aesthetics of rare woods.
    "In another important innovation, Trex will introduce a new
railing system that has a white textured surface with the appearance
of painted wood. Crafted from a durable composite material, it offers
an elegant look and also sets a new standard for easy installation.
    "To support our business and the many new product initiatives in
2005, we will kick off a major new print and television advertising
campaign that emphasizes the limitless design flexibility of Trex(R).
Built around the theme 'Create Your Space(TM)', the campaign will
emphasize to consumers that nothing looks and lasts like Trex(R)."
    Mr. Matheny concluded, "2004 to date has been another successful
year for our Company. Although the seasonality of our business results
in lower sales during the fourth quarter, we remain confident in our
previously announced guidance, which calls for net sales for 2004 to
total $240 to $245 million and earnings per diluted share to total
$1.75 to $1.80. Looking forward to 2005, we expect to grow both
revenue and earnings in the range of 20 - 25% for the year."
