LYDALL ANNOUNCES RETIREMENT OF CEO DAVID FREEMAN AND APPOINTMENT OF DALE G. BARNHART AS SUCCESSOR

MANCHESTER, CT, AUGUST 3, 2007 – Lydall, Inc. (NYSE:LDL)—The Board of Directors of Lydall, Inc. today announced that David Freeman has decided to retire as President and Chief Executive Officer of the Company, a position he assumed in July 2003. Following a transition period, Mr. Freeman will retire at the end of October. The Board also announced that Dale G. Barnhart has been appointed as President and Chief Executive Officer to replace Mr. Freeman. Barnhart will begin on August 27, 2007.

Freeman, a member of Lydall’s Board since 1998, came out of retirement in mid-2003 to become the Chief Executive Officer of the Company. Before joining Lydall, he was Chairman and CEO of Loctite Corporation until 2000. Following his retirement from Loctite, he was a Professor of International Business at Central Connecticut State University.

Freeman commented, “My time at Lydall has been a challenging and rewarding experience. When I accepted the position to lead Lydall four years ago, one of my first priorities was to strengthen the organization and the depth of our management team. With this accomplished, we directed our attention to renewing our focus on innovation through new-product development and on marketing efforts. And, finally, we tackled reducing costs and improving quality through our Lean Six Sigma program. I’m pleased with the progress that management and all employees have made on these fronts.

“The Board and I have been discussing the next phase of Lydall’s strategic growth for several months. I believe that whoever crafts the plan should be around to implement the plan, and I was not able to commit to this time frame. As a result, a search was begun for the next CEO of Lydall. That now being completed, I am happy to turn the leadership reins of Lydall over to Dale Barnhart. I have every confidence in Dale’s ability to take the Company to the next plateau, and I will assist him in any way I can. He has over 30 years of international business experience which will be very important to Lydall’s future growth. He also has proven strategic planning and implementation skills, as well as extensive knowledge of the markets that Lydall serves.

“I look forward to re-retiring, however, I will very much miss working with Lydall’s employees. They are a fine group of dedicated and talented people.”

Barnhart also complimented Lydall’s employees, “I’m looking forward to working with David Freeman and the management team at Lydall to ensure a smooth transition. I’ve heard great things about the employees of Lydall, both from the Board and from the market place. I’m fortunate to be joining the Company on the threshold of its next stage of growth, and I look forward to being a part of it.”

Barnhart (age 55) comes to Lydall from Synventive Molding Solutions where he has served as Chief Executive Officer since 2004. Synventive is a provider of hot runner systems, machine nozzles, temperature controllers and sprue bushings for the injection molding industry.
