                WAUSAU PAPER 2004 EARNINGS INCREASE 29 PERCENT


MOSINEE, WIS..JAN. 26, 2005..Wausau Paper (NYSE:WPP) today reported
fourth-quarter earnings of $5.1 million, or $0.10 per diluted share, compared
with $5.3 million, or $0.10 per diluted share, in the fourth quarter
of 2003.  Fourth-quarter 2004 earnings include after-tax losses of $0.02 per
diluted share related to the start-up and operation of Printing & Writing's
newly acquired Brainerd mill, and stock incentive charges of $0.01 per diluted
share.  Prior-year fourth-quarter earnings included stock incentive charges of
$0.01 per diluted share.  Net sales increased 10 percent to $262.4 million from
$239.3 million last year while shipments increased 3 percent.  Average selling
price improved in each of the company's three business segments with the most
significant gains occurring within Towel & Tissue and Specialty Products.

Net earnings for the year increased 29 percent to $20.4 million, or $0.39 per
diluted share, from $15.9 million, or $0.31 per diluted share, in 2003.  Net
sales increased 7 percent to $1,040.7 million from $971.4 million last year
while shipments increased 2 percent.  Current-year results include after-tax
losses of $0.02 per diluted share related to the start-up and operation of the
Brainerd mill and stock incentive charges of $0.03 per diluted share.  Prior-
year earnings included stock incentive charges of $0.02 per diluted share.

"Wausau Paper made strong progress in 2004 despite only modest improvement in
market conditions," commented Thomas J. Howatt, president and CEO.  "Full-year
earnings increased nearly 30 percent, with profit improvements in two of our
three business segments, and net sales exceeded $1 billion for the first time
in company history.  Much of this improvement can be attributed to continuing
progress in our strategic initiatives - new product development, pursuit of
niche markets, operational excellence, and benchmark service to our customers,"
Mr. Howatt continued.  "Revenues from products developed within the last three
years substantially exceeded our corporate goal of 25 percent; productivity
increased 2 percent, double our goal for the year; and cost-reduction results
exceeded our goal of 2 percent of prior year cost of sales."

In the fourth quarter, Specialty Products achieved its 10th consecutive quarter
of year-over-year improvement with operating profits of $6.4 million, more than
double the $2.6 million earned a year ago.  Net sales and shipments increased
13 percent and 4 percent, respectively.  "Selling price increases, sales mix
improvements and operational efficiency gains helped drive quarterly profits to
their highest level in more than five years," Mr. Howatt said.  "Crisp
execution over the last three years has created strong momentum, positioning
Specialty Products as a solid profit contributor."

Printing & Writing reported fourth-quarter operating profits of $0.4 million,
compared with $3.4 million last year.  Current-year results included fiber and
energy cost increases of more than $4 million and pre-tax operating losses of
$1.9 million related to the mid-November start-up and fourth-quarter operation
of the Brainerd mill.  Net sales and shipments increased 8 percent and 5
percent, respectively.  "Despite soft fourth-quarter demand and highly
competitive pricing, Printing & Writing gained share in its target markets,
with consumer products and premium paper shipments increasing 32 percent and 12
percent, respectively," said Mr. Howatt.  "While quarterly profits were
unfavorably affected by start-up expenses, the acquisition of the Brainerd mill
will allow us to expand our sales of higher-margin premium papers and improve
long-term profitability."

Towel & Tissue reported fourth-quarter operating profits of $7.9 million,
compared with $8.7 million last year.  Net sales increased 8 percent while
shipments declined 2 percent.  "Selling price increases and mix improvements
could only partially offset higher costs in the quarter including wastepaper,
purchased paper, and downtime associated with the planned replacement of a
paper machine hood at the Middletown mill," Mr. Howatt explained.  For the
year, net sales and shipments increased 6 percent and 1 percent, respectively.
"Shipments of our higher-margin value-added products increased 11 percent for
the year," commented Mr. Howatt.  "With only modest growth in the
away-from-home towel and tissue market, this increase demonstrates the value of
our niche-market focus."

Commenting on the outlook for 2005, Mr. Howatt said, "Market conditions remain
mixed with uncoated freesheet demand lagging towel and tissue and specialty
markets.  We have proven our ability to gain market share and increase earnings
in challenging market conditions and will once again leverage our strategic
initiatives to drive improvement and fuel growth.  Despite expected higher
fiber prices and natural gas costs well above historical averages, we expect
first quarter earnings to modestly exceed prior year results of $0.07 per
share, assuming a first quarter impact from Brainerd operations comparable to
the fourth quarter."

Wausau Paper's fourth-quarter conference call is scheduled for 11:00 a.m. (EST)
on Thursday, January 27, and can be accessed through the Company's web site at
www.wausaupaper.com under "Investor Information."  A replay of the webcast will

Note 1. Effective March 3, 2003, the Company acquired certain assets of a
        laminated papers producer.  The acquisition was accounted for as a
        purchase business combination and, accordingly, the purchase price has
        been allocated using the fair values of the acquired receivables,
        inventory, machinery and equipment, and identifiable intangible assets.
        No goodwill was recorded as a result of this acquisition. The acquired
        assets are included in the Printing & Writing business segment.

Note 2. During the second quarter of 2003, the Company's Towel & Tissue Group
        reached a settlement of all claims of the parties in its previously
        announced patent litigation.  As a result of the settlement, the
        Company recognized $4.2 million in pre-tax income as a fee for
        licensing certain patented dispenser technologies.

Note 3. On October 21, 2004, the Company acquired the assets of the Brainerd,
        Minnesota paper mill of the Missota Paper Company, LLC, for
        approximately $9.9 million.  The purchase price has been allocated
        using the fair values of the acquired property, plant, and equipment.
        The Company assumed no liabilities of the mill.  No goodwill or other
        intangible assets resulted from the transaction. The acquired assets
        are included in the Printing & Writing business segment.

Note 4. Interim Segment Information
        The Company's operations are classified into three principal reportable
        segments:  Printing & Writing, Specialty Products and Towel & Tissue,
        each providing different products.  Separate management of each segment
        is required because each business unit is subject to different
        marketing, production and technology strategies.

        Printing & Writing produces a broad line of premium printing and
        writing grades at manufacturing facilities in Brokaw, Wisconsin;
        Groveton, New Hampshire; and Brainerd, Minnesota.  Printing & Writing
        also includes two converting facilities that produce laminated roll
        wrap and related specialty finishing and packaging products, and a
        converting facility that converts printing and writing grades.
        Specialty Products produces specialty papers at its manufacturing
        facilities in Rhinelander, Wisconsin; Mosinee, Wisconsin; and Jay,
        Maine.  Towel & Tissue  produces a complete line of towel and tissue
        products that are marketed along with soap and dispensing systems for
        the "away-from-home" market.  Towel & Tissue operates a paper mill in
        Middletown, Ohio, and a converting facility in Harrodsburg, Kentucky.

        Sales, operating profit, and asset information by segment is as
