TREX COMPANY, INC. Date: May 4, 2007 /s/ Anthony Cavanna ------------------------- Anthony Cavanna Chairman and Chief Executive Officer

                                                                    Exhibit 99.1

          Trex Company Announces First Quarter 2007 Results

    WINCHESTER, Va.--(BUSINESS WIRE)--May 4, 2007--Trex Company, Inc.
(NYSE: TWP), manufacturer of Trex(R) decking, railing and fencing,
today announced financial results for the first quarter ended March
31, 2007.

    Net sales for the first quarter of 2007 totaled $115.9 million,
compared to net sales of $105.3 million for the first quarter of 2006.
The Company reported net income for the 2007 first quarter of $3.7
million, or $0.25 per diluted share, compared to net income of $4.1
million, or $0.27 per diluted share, for the 2006 first quarter.

    Chairman and Chief Executive Officer Anthony J. Cavanna commented,
"Our 'early buy' program was successful in the first quarter, and
fulfilled our goal of positioning Trex well for the coming decking
season. During the quarter, we also began shipping our new Trex
Contours(TM) line of decking and Trex Seclusions(R), our new privacy
fencing system.

    "While we are pleased with our shipment volume in the first
quarter, our bottom-line results were negatively impacted by
lower-than-expected plant productivity and higher-than-expected plant
overhead expenses as we continue to emphasize quality and introduce
new products. Selling, general and administrative expenses were
favorably impacted as a result of a $3.25 million legal settlement.
Increased interest expense, driven by higher debt levels reflecting an
increase in working capital, also negatively affected our results.

    "As we move through the second quarter, we are accelerating our
consumer brand-building activities to expand Trex's market share in
all of our distribution channels. We believe we are positioned to have
a successful year with our big box channel partners as a result of
improved merchandising and the expanded number of stocking stores. We
remain focused on completing our strategic productivity projects by
mid-year, after which we expect to begin realizing the benefits in the
form of improved quality product at lower manufacturing cost. We also
look forward to building out our distribution network for Trex
Seclusions during the remainder of 2007.

    "Despite these many positives, we remain cautious about market
conditions for 2007 due to uncertain economic conditions related to
the overall activity in the homebuilding and remodeling sectors. We
have therefore reviewed and adjusted our guidance for 2007. For the
full year 2007, we now expect net sales to be in the range of $340 to
$360 million and earnings per diluted share to be between $0.65 and
$0.75. For the first half of 2007, we expect net sales to be in the
range of $220 to $230 million and earnings per diluted share to be
between $0.60 and $0.70."

    Trex will hold a conference call to discuss its 2007 first-quarter
results on Friday, May 4 at 10:00 a.m. ET. A live webcast of the
conference call will be available to all investors at the Trex Company
