Citing increased raw materials and energy costs, Congoleum announced it plans to institute a 2 percent price increase across all products except commercial tile. The resilient flooring maker said the new pricing structure will take effect Sept. 1.

Dennis P. Jarosz, vp sales and marketing for Congoleum, said the price increases were necessary in light of rising raw material costs.

"While raw materials have not risen as dramatically as they did a year ago, there have been increases," he noted. "For instance, the plasticizer we use has risen significantly in cost over the past several months."

"The price we all pay for the energy we use has risen dramatically over the past two years," he added.
