To do this, the company converted the former Hundson Motor Car Plant in Detroit. (The thickness of Dow's panel was the same 57 mm as Wright's panel, but in this case, 40 mm was taken up by the insulation.) The material was used in the construction of Dow's own house in Michigan, which became a showcase for SIP panels. As a result, a prototype of an improved SIP panel appeared - a "sandwich" with two layers of glued plywood and polystyrene insulation in between. Dow, a student of Wright and brother of the CEO of Dow Chemical, continued his experiments in creating structural and insulation materials and created ergonomic three-layer sandwich panels with polyester and plywood covering. In 1951, there was a real revolution in the production of SIP panels, namely the introduction of Styropor (expanded polystyrene), an insulating material, by the German chemical concern BASF. The material gained wide publicity, and even the First Lady of the United States at the time, Eleanor Roosevelt, took notice.įrom 1947, mass testing of variations of sandwich panels began, including panels made of plywood and corrugated cardboard. In 1937, in the same state of Wisconsin, the first administrative building was constructed using sandwich panels, which later became one of the buildings of the University of Wisconsin-Madison. The total thickness of the panel was 57 mm and consisted of three layers of glued plywood and two layers of tar paper. It is worth noting that this house still stands. In 1935, the American architect Frank Lloyd Wright used sandwich panels with a cellular filler in the design of the one-story Unsonian cottage, which was intended as an example of affordable housing. The first prototype of a modern SIP panel was developed at the US Forest Products Laboratory (FPL) in Madison, Wisconsin, in the early 1930s. However, it was in Canada where the technology was perfected, and buildings constructed using SIP panels are now referred to as Canadian. In fact, their production was first launched in the United States in the 1930s. SIP panels are often associated with Canadian construction technology.
