Edward Scherrer

Chief Innovation Officer/Engineer

Better building has been a constant in his life. Ed started with custom home construction and continued on with Insulating Concrete Form (ICFs), radiant heating systems, and finally with InSoFast panels. Ed’s passion is continually looking for ways to improve how things are built.

When ICFs were introduced to Ed, he took it on with complete enthusiasm. While ICFs provide a superior structure, the actual construction process was very technical and difficult. Ed had to develop for homeowners and contractors, how to seminars and developed an engineering package to aid the building officials. Ed contributed to the patent for improving of a new ICF design which maximized sizing flexibility and reduced shipping costs.

InSoFast panels were born from his experiences – in the ICF industry. Ed took the benefits: continuous insulation and built-in studs; and eliminated the technical and difficult a that = InSoFast. A product that was easy for DIYers and still answered all the issues that concerned the building science community. Ed develops fail-safe-in-the-field products for the homeowner to the seasoned building science professional.
