   Trex Company Announces Fourth-Quarter and Year-End 2006 Results

    WINCHESTER, Va.--(BUSINESS WIRE)--March 26, 2007--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, 2006.

    Net sales for the fourth quarter of 2006 totaled $32.1 million,
compared to net sales of $44.0 million for the fourth quarter of 2005.
The Company reported a net loss for the 2006 fourth quarter of $13.8
million, or $0.93 per diluted share, compared to a net loss of $10.9
million, or $0.73 per diluted share, for the 2005 fourth quarter.

    For the full 2006 year, Trex reported net sales of $337.0 million,
compared to net sales of $294.1 million for 2005, which represented a
14.6% increase. Income from operations for 2006 was $6.1 million,
compared to income from operations of $2.9 million for 2005. Net
income for 2006 was $2.3 million, or $0.16 per diluted share, compared
to net income of $2.3 million, or $0.15 per diluted share, for 2005.

    "Revenues for the fourth quarter, our seasonally slow period,
slightly exceeded our expectations, even as distributors and dealers
remained cautious about spending in a weakening building products
market," commented Chairman and Chief Executive Officer Anthony J.
Cavanna. "Considering the soft market conditions, we are particularly
pleased with our full-year top line growth, which illustrates the
success we have achieved in raising our product quality; the strength
of the Trex(R) brand, backed by our well-established reputation for
product innovation; the expansion of our distribution network; and the
initial traction we have gained with our newly introduced Trex
Seclusions(R) fencing product line."

    Mr. Cavanna continued, "Even though we produced strong top line
results, we fell short of our net income goals for the quarter and the
year. Higher manufacturing costs, reflecting increases in the cost of
plastic raw materials, increased plant overhead expenses and lower
plant productivity negatively impacted our bottom-line results. In
particular, we incurred higher plant labor costs, increased packaging
costs and lower production yields as we implemented our product
quality program.

    "Although we succeeded in improving product quality, our
corresponding goal of improving manufacturing efficiencies is taking
longer than anticipated. Delays in installing new equipment and in
improving processes are contributing to the extended timetable. In
2007, we are investing approximately $25 million in equipment to
improve manufacturing efficiencies and lower product cost. While we
still expect to begin realizing the benefits of these initiatives in
the second half of 2007, we expect to obtain the full impact in 2008."

    Mr. Cavanna concluded, "Positive responses to our quality programs
combined with our broad product offering and solid channel
relationships, position Trex for growth despite persistent weakness in
the home remodeling and renovation market. New products, including
Trex Contours(TM) and improved Trex Brasilia(R), in addition to our
recently introduced Trex Seclusions(R) product line, will contribute
to 2007 revenue growth. Finally, in 2007 we will continue to broaden
our distribution by having Trex(R) decking and railing products
stocked nationally in Home Depot and Lowe's stores as a complement to
the effective professional distribution channel we have developed over
the past 10 years. By being broadly represented in all distribution
channels, we can best continue to expand the market for composite
decking, build awareness for the Trex(R) brand and increase our
Company's sales.

    "In 2007, we believe market conditions will remain soft. As a
result, we are revising our 2007 guidance and now expect net sales in
the range of $350 to $370 million and earnings per diluted share
between $0.80 and $0.90. For the first half of 2007, we expect net
sales to be between $225 and $235 million and earnings per diluted
share in the range of $0.70 to $0.80."

    Trex will hold a conference call to discuss its 2006
fourth-quarter results on Monday, March 26 at 1:00 p.m. ET. A live
webcast of the conference call will be available to all investors at
the Trex Company website at www.trex.com. The call will also be
