Plant Closures [Abstract]
Plant Closures	16. Plant Closures In June 2011, as a result of excess capacity in the PVC pipe market and in an effort to reduce costs and optimize operations, the Company closed its Springfield PVC pipe facility and fully impaired the associated assets. Asset impairment costs and severance and other costs related to the PVC pipe facility closure recorded in 2011 were $1,975 and $1,389, respectively. The fair value of the impaired assets were determined using internally developed, unobservable inputs (Level 3 inputs in the fair value hierarchy of fair value accounting) based on the projected cash flows of the pipe facility. In October 2009, as a result of excess capacity due to the weak construction market and in an effort to reduce total costs, the Company closed its Bristol, Indiana PVC pipe facility and moved the production to the Company's other PVC pipe facilities. Asset impairments and severance and other costs related to closed PVC pipe facilities, including the Bristol facility, were $3,898 and $457, respectively, for the year ended December 31, 2009. The Company determined the fair value of the impaired assets using internally developed, unobservable inputs (Level 3 inputs in the fair value hierarchy of fair value accounting) based on the projected cash flows of the closed plants. The remaining carrying value of these assets after impairment was $2,167.
