In 1997, the state of Wisconsin came out with a new code for measuring R-values in masonry. This effected masonry wall systems tremendously. With this in mind, officers of Ed Prager and Sons attended a masonry conference in which they came across PolyMaster foam insulation. As it turned out PolyMaster had an injected foam insulation which increased the R-value by 43% over any other masonry insulations on the market. Realizing the impact on our market, MasterFoam Insulation was born in April of 1997.

Since 1997, MasterFoam has acquired vast experience in this relatively new field. Having foamed with three different brand names, MasterFoam has found out which brands work the best in our area as well as problems associated with others. With this experience we are called on regularly for technical and problem solving information.

With heat costs rising and a demand for the highest quality insulation products, MasterFoam has expanded into the spray foam market. These products offer a next generation of insulating and sealing components as you will discover in this web site. We know you will be intrigued with our company and products, so we invite you to travel on our tour through our web site.


MasterFoam provides residential and commercial foaming products. We have two injection trucks and two urethane spray foam rigs. We own our own boom lift and scissors lift. Our projects list will give you an idea the size of work we can handle!
