          Trex Company Announces First Quarter 2006 Results

    WINCHESTER, Va.--(BUSINESS WIRE)--April 27, 2006--Trex Company,
Inc. (NYSE:TWP), manufacturer of Trex(R) decking and railing, today
announced financial results for the first quarter ended March 31,
2006.
    Net sales for the first quarter of 2006 totaled $105.3 million,
compared to net sales of $89.9 million for the first quarter of 2005,
which represented a 17.1% increase. The Company reported net income
for the 2006 first quarter of $4.2 million, or $0.29 per diluted
share, compared to net income of $8.4 million, or $0.56 per diluted
share, for the 2005 first quarter.
    Chairman and Chief Executive Officer Anthony J. Cavanna commented,
"The success of our 'early buy' program - designed to sell Trex
products into distribution before the deck-building season moves into
high gear each spring - got 2006 off to a good start for Trex. The
combination of strong product demand and low inventory levels at our
plants led to increased manufacturing utilization throughout the
period.
    "We made progress with the series of initiatives we implemented in
the fourth quarter of 2005 to enhance product quality and packaging
and to improve manufacturing efficiencies. However, our profitability
in the first quarter of 2006 was negatively affected by the increased
cost of plastic raw materials due to our use of resin to facilitate
the production of high quality product as we increased our
manufacturing plant utilization.
    "As we move through the second quarter, our consumer brand
building activities are picking up on schedule in order to help us
drive the conversion of the market from wood to composite decking and
extend Trex's pre-eminent position in the composite wood market. With
the expanded line of products we have introduced over the past two
years, Trex offers a full range of decking and railing at price points
that satisfy all segments of the market. We expect to further enhance
plant efficiencies and continue emphasizing product quality as the
year continues."
    The Company affirmed its previously announced guidance for the
first six months of 2006, which calls for net sales to range from $220
million to $230 million and earnings per diluted share to range from
$0.57 to $0.62. The results projected in this guidance compare to net
sales of $173 million and earnings per diluted share of $0.50 in the
first six months of 2005.
    Trex will hold a conference call to discuss its 2006 first-quarter
results on Thursday, April 27 at 11:00 a.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 simulcast at
