EXHIBIT INDEX Exhibit Number Exhibit Description - -------------- ------------------- 99.1 Press release dated November 1, 2006

                                                                    Exhibit 99.1

          Trex Company Announces Third Quarter 2006 Results


    WINCHESTER, Va.--(BUSINESS WIRE)--Nov. 1, 2006--Trex Company, Inc.
(NYSE: TWP), manufacturer of Trex(R) decking and railing, today
announced financial results for the third quarter ended September 30,
2006.

    Net sales for the third quarter of 2006 totaled $78.1 million,
compared to net sales of $77.4 million for the third quarter of 2005.
The Company reported net income for the 2006 third quarter of $4.6
million, or $0.31 per diluted share, compared to net income of $5.2
million, or $0.35 per diluted share, for the 2005 third quarter.

    For the nine months ended September 30, 2006, Trex Company
reported net sales of $304.8 million, compared to net sales of $250.1
million for the nine months ended September 30, 2005. Net income for
the 2006 nine-month period totaled $15.9 million, or $1.06 per diluted
share, compared to $12.6 million, or $0.84 per diluted share, for the
2005 nine-month period.

    Chairman and Chief Executive Officer Anthony J. Cavanna commented,
"In an increasingly difficult market environment, Trex's revenue rose
1% in the third quarter as favorable pricing trends offset slowing
sales. For the first nine months of 2006, our revenue increased 22%,
reflecting strong demand for Trex composite decking and, based on
preliminary data, share gain in both the professional and retail
channels. During the quarter, we maintained our focus on product
quality and continued to produce to our higher standards even though,
in the short term, these initiatives have negatively impacted labor
costs and production yields.

    "The fourth quarter is always a slower period for our industry,
and Trex typically reports a loss due to the highly seasonal nature of
deck installations. We expect these trends to be even more pronounced
than usual in 2006, as distributors and dealers reduce their overall
inventories in response to current market conditions. In anticipation
of this slowdown, we plan to temporarily shut down certain
manufacturing lines.

    "As a result of these factors, we are revising our financial
guidance for 2006, and now expect full-year net sales of approximately
$320 to $330 million and earnings per diluted share in the range of
$0.35 to $0.45. This compares to net sales of $294.1 million and
earnings per diluted share of $0.17 in 2005."

    Mr. Cavanna continued, "We believe Trex is well-positioned for
2007 due to the many meaningful new product, manufacturing efficiency
and cost savings initiatives we now have underway. As part of our
effort to offer compelling products that satisfy all segments of the
market, we are adding Trex Contours(TM) to our decking line. Featuring
a bold new grain pattern and structured profile that can be
manufactured at a lower cost while offering the same trusted Trex(R)
quality, Trex Contours(TM) will represent an exceptional value to
consumers.

    "Another contributor to growth is our improved Trex Brasilia(R),
our top-of-the-line decking, which will feature a trimmer profile and
improved 'streaking' to enhance its tropical hardwoods look.
Responding to demand from contractors, we will also add 4 x 4 hollow
post sleeves and boxed railing kits to our product line-up, both of
which will facilitate the installation of Trex(R) products.

    "In addition, we will begin a regional roll-out of Trex
Seclusions(TM), the new privacy fencing system that we have been
testing in 2006 with great success. Contractors and consumers have
been extremely enthusiastic about not only the product's aesthetics,
but also its functionality and ease of installation.

    "On the cost side, we have a wide array of manufacturing and R&D
initiatives underway that we also expect to positively impact the
Company's 2007 results, particularly in the second-half of the year.
These include investments in the handling and processing of raw
materials that will provide more control over plastic streams and
improve production yields. We are also making investments in several
other manufacturing processes that will result in significant cost
savings."

    "Product innovation and leadership in low cost have always been
vital to Trex's long-term success," Mr. Cavanna concluded, "and we are
especially excited about our expanded decking, railing and fencing
offerings. Combined with the manufacturing efficiency initiatives we
have underway, we expect these to make 2007 a successful year for
Trex. We estimate that revenue will be in the range of $370 to $390
million and earnings per share in the range of $1.05 to $1.25."

    Trex will hold a conference call to discuss its 2006 third-quarter
results on Wednesday, November 1 at 10:30 a.m. ET. A live webcast of
the conference call will be available to all investors at the Trex
