History of Spray Foam Insulation

Otto Mayer – Polyurethane Foam 

In the 1940’s German scientist and chemist, Otto Mayer, invented spray foam polyurethane. The polyurethane foam was brought to the United States during the war for aviation and nautical purposes.

Walter Baughman – The “Blend-o-Meter”

The Blend-O-Meter was invented by Walter Baughman and allowed individuals to mix the foam easier.  It was a very complicated machine that allowed people to add the individual foam components to the chemical solution and create plastics.

Fred Gusmer -The Proportioner

Gusmer created the foam proportioner and the spray foam gun which allowed individuals to accurately proportion the a and b chemicals and mix foam correctly.
