National Gypsum to expand cement board operations

National Gypsum Co. announced it is expanding its PermaBase cement backerboard production near Montreal, Quebec. The addition will increase capacity at the Canadian plant by 50 percent.

In 1998, the company acquired Unifix Inc., a Canadian manufacturer of cement backerboard with operations in Bromont, Quebec. After the purchase, National Gypsum completed a plant near Jacksonville, Fla., and built two additional plants, one near Dallas and the other in Clinton, Ind.
