                 Trex Company Completes Year of Strong Growth;
                     2004 Revenue Increases 33%, EPS up 28%



    WINCHESTER, Va.--(BUSINESS WIRE)--Feb. 17, 2005--Trex Company,
Inc. (NYSE: TWP), manufacturer of Trex(R) decking and railing, today
announced financial results for the fourth quarter and fiscal year
ended December 31, 2004.
    Net sales for the 2004 fourth quarter totaled $29.6 million
compared to $21.9 million for the 2003 fourth quarter. The net loss
decreased to $0.4 million, or $0.02 per diluted share, for the 2004
fourth quarter from a net loss of $0.8 million, or $0.05 per diluted
share, for the 2003 fourth quarter.
    Chairman and Chief Executive Officer Robert Matheny commented,
"Trex Company typically reports a loss in the fourth quarter due to
the highly seasonal nature of deck installations, whose peak periods
occur from late winter through September. As is usual in the fourth
quarter, we built product inventory to prepare for the heavy demand we
anticipate during the upcoming peak season. During the period, our
cost of sales was negatively affected by the higher cost of plastic
raw materials."
    For the full 2004 year, Trex Company reported net sales of $253.6
million compared to $191.0 million for 2003, which represents an
increase of 33%. Net income increased 29% to $27.2 million, or $1.83
per diluted share, from net income of $21.0 million, or $1.43 per
diluted share, for 2003.
    Mr. Matheny continued, "As our financial results clearly
demonstrate, 2004 was a successful year for Trex. As the demand for
composite decking and railing products continued to grow, we took
steps to expand our market leadership position. We introduced a series
of products - Trex Origins(TM), Trex Accents(TM), and Trex Designer
Series Railing(TM) - that have been well accepted by the market. In
fact, Trex Accents(TM) has already established itself as the leading
wood grain-textured deck board in the composite market. We launched a
relationship with The Home Depot designed to complement our existing
distribution channel and reach a new set of consumers and contractors.
In addition, we started construction on our third manufacturing plant,
in Olive Branch, Mississippi.
    "In 2005, we will capitalize even further on the growing
popularity of composite decking and railing. In December, we began
shipping Trex Brasilia(TM), a new line of deck boards, trim profiles
and railings that feature the look of tropical hardwoods, including
subtle shadings and color variations. Our Trex Artisan Series
Railing(TM) will also debut in 2005. This new railing system has a
white textured surface with the appearance of painted wood and is
crafted from a durable composite material that offers an elegant look
while setting a new standard for easy installation. Our new
advertising campaign, 'Create Your Space(TM)', kicked off in February
and is designed to demonstrate the broad design flexibility Trex
Company's products offer homeowners looking to create an outside
living environment."
    Mr. Matheny concluded, "We believe Trex Company is well positioned
to take advantage of the extraordinary opportunities that exist in our
market and to continue expanding our leadership role. For 2005, we
expect net sales and earnings per diluted share to increase
approximately 18% to 22%."
