CHICOPEE, Mass. -- Menck USA has closed its high-tech window manufacturing operation and a buyer is being sought. According to MassLive, Menck shut down the factory in mid-January after investors decided not to put more money into the enterprise, according to a letter to creditors released to The Republican and MassLive by attorney Michael B. Katz of the Bacon Wilson law firm.

German window manufacturer Menck relocated a planned $20 million window plant from Vermont to Chicopee, MA. Plans to use European woodworking machinery voided the Vermont factory.
