MFM Building Products
A Deep Tradition of Excellence to the Construction Industry
MFM Building Products, founded in 1961 by Robert E. Simpson, offers the construction industry more than 57 years of knowledge and expertise in the manufacture of waterproofing and weather barrier products. From humble beginnings, this family-owned manufacturing company has continued to grow and foster new product development, improved product performance, and help reduce overall costs with a value-based philosophy.
In 2017, the company became an employee-owned ESOP company with a bright future of continuing the tradition that the company was founded upon: pride in workmanship to provide the highest quality products for our customers. MFM products are proudly manufactured in the United States.
