                                                                    Exhibit 99.1

          Trex Company Announces Second Quarter 2005 Results

    WINCHESTER, Va.--(BUSINESS WIRE)--July 27, 2005--Trex Company,
Inc. (NYSE: TWP), manufacturer of Trex(R) decking and railing, today
announced financial results for the second quarter ended June 30,
2005.
    Net sales for the 2005 second quarter totaled $82.9 million,
compared to $83.4 million for the second quarter of 2004. The Company
reported a net loss for the 2005 second quarter of $1.0 million, or
$0.07 per diluted share, compared to net income of $11.1 million, or
$0.75 per diluted share, for the 2004 second quarter.
    For the six months ended June 30, 2005, Trex Company reported net
sales of $172.8 million, compared to net sales of $159.7 million for
the six months ended June 30, 2004. Net income for the 2005 six-month
period totaled $7.4 million, or $0.50 per diluted share, compared to
$20.4 million, or $1.38 per diluted share, for the 2004 six-month
period.
    Chairman and Chief Executive Officer Robert Matheny said, "As we
previously announced, 2005 has been more challenging than expected due
to a variety of factors. While our second-quarter revenues exceeded
the estimates we provided in June, our sales for the period were still
negatively affected by higher-than-anticipated trade inventory levels
entering 2005 and a resulting adjustment of inventory by retailers and
distributors. Sales of Trex products reported at the retail level
exceeded our sales growth at the Company level, reflecting a draw-down
of channel inventory. Bad weather in many parts of the U.S. further
impeded the sell-through of our products by delaying the onset of this
year's decking season, while constraints in railing production
capacity restricted our ability to capitalize on the growth in demand
in this product area and also affected related decking sales.
    "Although the Company's bottom-line results for the 2005 second
quarter also exceeded the earnings estimate we provided in June, our
earnings were negatively affected by a substantial increase in the
price of plastic raw materials and a less-favorable manufacturing
performance than in last year's second quarter.
    "While our results in the first half of 2005 were disappointing,
we are encouraged by the positive reaction to our new decking
products, Trex Accents(R) and Trex Brasilia(TM). Both have been
well-received and are setting the standard for aesthetics in the
composite decking market. Although trade inventories are not highly
transparent, we believe the inventory adjustment is now largely behind
us and that the stronger velocity of Trex products we have been seeing
at the retail level will gradually be reflected in our Company sales.
    "In addition, we are actively pursuing a number of initiatives
that we expect will further strengthen our momentum in the second half
of the year, including retail expansion in many channels and
pull-through oriented marketing programs. We are also reducing SG&A
spending and pursuing manufacturing efficiencies at each of our three
plants. However, fixed manufacturing costs will be under-absorbed in
the second half, as we slow our production rate to achieve the optimal
finished goods inventory level at year-end.
    "Beyond working to maximize results in the second half of 2005, we
are vigorously pursuing initiatives to strengthen Trex Company for
2006. We intend to continue to set the standard for market-based
innovation in the category, building on our recent success with Trex
Accents, Trex Brasilia, and the new Trex Artisan Series Railing(TM).
In particular, we will continue to leverage our leading brand to
create product awareness, assurance, and interest."
    The Company confirmed its most recent guidance for 2005, announced
on June 22, 2005, which called for net sales to range from $270
million to $280 million and diluted earnings per share to range from
$0.50 to $0.60.
    The Company has scheduled a conference call for 10:00 a.m. ET on
July 28, 2005 to discuss its second-quarter 2005 results. A live
webcast of the conference call will be available to all investors at

August 3, 2005. To listen to the telephone replay, dial 706-645-9291

    The statements in this press release regarding the Company's
expected sales performance and operating results, its projections of
net sales, net income, earnings per share and costs, its anticipated
financial condition and its business strategy constitute
"forward-looking statements" within the meaning of Section 27A of the
Securities Act of 1933 and Section 21E of the Securities Exchange Act
of 1934. These statements are subject to risks and uncertainties that
could cause the Company's actual operating results to differ
materially. Such risks and uncertainties include the extent of market
acceptance of the Company's products, the sensitivity of the Company's

and Exchange Commission on March 16, 2005 and its subsequent filing on
Form 10-Q for the first quarter of 2005 discuss some of the important
factors that could cause the Company's actual results to differ
materially from those expressed or implied in these forward-looking
statements. The Company expressly disclaims any obligation to update
or revise publicly any forward-looking statements, whether as a result
