About WNC Foam


Walter N. Coffman is a leader in quality fabrication of EPS foam shapes (Expanded Polystyrene) for nearly any interior or exterior architectural design element.  Our foam creations are a smart alternative to work done in metal, wood or concrete. Each piece is molded and finished to replicate most any finish including painted wood, stone, and other precast materials.

Walter N. Coffman has been involved in the plastering industry since 1946, becoming a contractor in 1956. Over the years the plastering industry evolved in many directions with the biggest change being foam shapes. We began creating foam shapes for in-house plaster projects. We gradually gained experience to the point that our reputation for high quality products led to opening our doors to the public.
