      Kadant's Composite Building Products Business Achieves Profitability


ACTON, Mass., April 10, 2003 - Kadant Inc. (AMEX:KAI) announced that its Kadant
Composites Inc. subsidiary will report operating income of approximately $80,000
for the first quarter of 2003, on approximately $4.3 million in sales of
composite building products. This marks the first profitable quarter for the
composites business, a result of efforts within the past year to broaden product
distribution, primarily of its decking systems. Kadant plans to announce first
quarter results for the total company on April 30, 2003.

         "We're pleased to have met our goal of profitability during the first
quarter of 2003 in the composites business," said William A. Rainville, chairman
and chief executive officer of Kadant. "While we still have much work ahead,
including expanding the distribution of our GeoDeck(TM) products to the West
Coast and increasing production capacity, this represents an important milestone
in our development of this business."

         Kadant Composites Inc. develops, manufactures, and sells composite
building products - primarily decking systems and roof tiles - made from
recycled fiber, plastic, and other materials.

         Kadant Inc. is a leading supplier of a range of products for the global
papermaking and paper recycling industries, including stock-preparation
equipment, water-management systems, and papermaking accessories. The company
also develops and manufactures composite building materials produced from
recycled fiber and plastic. Kadant, based in Acton, Massachusetts, reported $186
million in revenues in 2002 and employs approximately 1,100 people worldwide.
