                WAUSAU PAPER ANNOUNCES SECOND-QUARTER EARNINGS


MOSINEE, WIS..JULY 25, 2005..Wausau Paper (NYSE:WPP) today reported a net loss
for the second quarter of 2005 of $2.7 million, or $0.05 per share, compared to
earnings of $3.7 million, or $0.07 per share, last year.  Net sales rose 4
percent to $275.3 million, and shipments increased less than 1 percent to
222,000 tons.

Second-quarter operating results included after-tax charges of $6.0 million, or
$0.12 per share, related to the previously announced closure of Printing &
Writing's sulfite pulp mill in Brokaw, Wisconsin, and after-tax losses of $2.4
million, or $0.05 per share, related to operation of its recently acquired
paper mill in Brainerd, Minnesota.  Also included in the current quarter were
after-tax stock incentive credits of $0.5 million, or $0.01 per share, compared
with charges of $1.3 million, or $0.02 per share last year.

For the first half of 2005, the Company reported a net loss of $0.8 million, or
$0.01 per share, compared with net earnings of $7.2 million, or $0.14 per
share, during the comparable period in 2004.  In addition to sulfite pulp mill
closure costs of $0.12 per share, results for the first half of 2005 included
after-tax losses of $5.6 million, or $0.11 per share, for the Brainerd mill,
and stock incentive credits of $0.03 per share, compared with charges of $0.03
per share last year.  Net sales increased 5 percent to $543 million while
shipments increased 2 percent to 443,000 tons.

In regard to second-quarter results, Thomas J. Howatt, president and CEO,
stated, "Top-line growth was achieved despite challenging business conditions,
demonstrating the value of our niche market strategy.  Our focused product
development efforts -- and the continued introduction of new products such as
Towel & Tissue's OptiCore{trademark} tissue and dispensing system and Printing
& Writing's Exact Ice{trademark} high-brightness paper -- resulted in revenues
from products developed within the last three years exceeding our corporate
target of 25 percent."

Specialty Products reported second-quarter operating profits of $3.8 million,
compared with $4.8 million last year.  Net sales and shipments declined 4
percent and 8 percent, respectively.  "Selling price increases and mix
enhancement could only partially offset the impact of reduced sales volume and
higher manufacturing costs -- most notably market pulp and energy," Mr. Howatt
explained.  He pointed out that 2004 shipments were a record for any quarter.

Printing & Writing reported second-quarter operating losses of $13.1 million,
compared with operating profits of $0.6 million last year.  Net sales and
shipments increased 8 percent and 10 percent, respectively.  Second-quarter
results included pre-tax pulp mill closure charges of $9.5 million, consisting
primarily of non-cash charges related to the write-down of inventory and
accelerated depreciation of long-lived assets.  In addition, second-quarter
results included operating losses of $3.8 million at Brainerd.  "Our Printing &

Writing business continues to face weak market conditions as uncoated freesheet
demand declined in each of the first six months of 2005," Mr. Howatt commented.
"Despite this weakness, we grew market share while increasing shipments by 10
percent, remaining focused on building the sales volume and product mix
necessary to profitably position Brainerd.  Success in developing new products
and reducing costs are critical to improving Printing & Writing's financial
performance.  We are actively pursuing both -- as evidenced by the recent
introduction of Exact Ice and the announced changes at Brokaw -- to help
achieve this improvement."

Towel & Tissue's second-quarter operating profits increased 22 percent to $9.9
million from $8.1 million last year.  Net sales and shipments increased 16
percent and 7 percent, respectively.  "Despite only modest market growth, our
Towel & Tissue business posted impressive sales gains in the first half of 2005
including a 5 percent increase in total shipments and 9 percent gain in higher-
margin value-add products," Mr. Howatt said.  "Together with improved selling
prices, these gains more than offset higher purchased parent roll costs,
helping drive operating profits to record second-quarter levels."

Looking to the third quarter, Mr. Howatt noted, "Towel and tissue market
conditions remain solid while demand for specialty products and printing papers
has clearly softened.  Uncoated freesheet markets remain the industry's weakest
segment with no sign of near-term improvement and, although market pulp costs
have eased slightly, energy and chemical costs remain at elevated levels.  We
expect third-quarter earnings, assuming continued improvement at Brainerd, to
only modestly exceed second-quarter levels of $0.06 per share, excluding
sulfite pulp mill charges."

on Tuesday, July 26, and can be accessed through the company's Web site at

Note 1. Balance sheet amounts at June 30, 2005, are unaudited.  The December
        31, 2004, amounts are derived from audited financial statements.

Note 2. Pulp Mill Closure
        In July 2005, the Company announced plans to permanently close the
        sulfite pulp mill at its Brokaw, Wisconsin, facility.  The pulp mill
        closure is expected to be substantially completed by the end of 2005
        and will result in the elimination of approximately 60 jobs, or 11
        percent of the facility's workforce.  The related long-lived assets
        will be abandoned.  The cost of sales for the period ended June 30,
        2005, as reflected in the Condensed Consolidated Statements of
        Operations, include $9.3 million in pre-tax charges for accelerated
        depreciation and an adjustment of pulp mill inventory to net realizable
        value.  Restructuring expense for the period ended June 30, 2005,
        reflects a pre-tax charge of $0.2 million for certain assets disposed
        as a direct result of the closure.  Additional pre-tax closure charges
        of approximately $35 million are expected to be recognized over the
        next 12 months, with $23 million in the third quarter of 2005, $11
        million in the fourth quarter of 2005, and $1 million in the first half
        of 2006.

Note 3. Interim Segment Information
        The Company has reclassified certain prior-year interim segment
        information to conform to the 2005 presentation.  The reclassification
        is the result of a reporting change, effective January 1, 2005, for two
        converting facilities from the Printing & Writing segment to the
        Specialty Products segment.

        The Company's operations are classified into three principal reportable
        segments: Specialty Products, Printing & Writing, 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.

        Specialty Products produces specialty papers at its manufacturing
        facilities in Rhinelander, Wisconsin; Mosinee, Wisconsin; and Jay,
        Maine.  Specialty Products also includes two converting facilities that

        produce laminated roll wrap and related specialty finishing and
        packaging products.  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 a converting facility that converts
        printing and writing grades.  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.
