While affirming the district court's denial of coverage under policies that defined occurrence as an accident, the Third Circuit remanded for further consideration of the policies containing an expected and intended definition of occurrence. Sapa Extrusions, Inc. v. Liberty Mut. Ins. Co., 2019 U.S. App. LEXIS 27668 (Sept. 13, 2019).
Sapa manufactured aluminum extruded profiles which were used for door and window frames. A pretreatment coating process was used in several aluminum clad windows and doors. Several stages were involved including cleaning and degreasing to remove organic and inorganic materials, chemical etching, and chemical coating to assist with paint adherence. For decades, Sapa supplied profiles to Marvin Lumber and Cedar Company. Marvin incorporated these extrusions with other materials to manufacture aluminum doors and windows. If an extrusion was defective, the whole window or door would have to be replaced. Between 2000 and 2010, Sapa sold 28 million windows and doors.
