MFM Building Products, a manufacturer of a full envelope of waterproofing and weather barrier products for the building industry, turns 55 years old this year.

MFM Building Products was founded in 1961 by Robert E. Simpson. Initially, the company manufactured products used for wrapping underground pipes to protect them from water penetration and to prevent pipe contents from becoming contaminated. MFM expanded this technology to develop sealing and waterproofing products for use within the general construction industry.

Today, MFM manufactures a wide array of weather barrier products that include door and window flashing tapes, low-slope roofing membranes, roofing underlayments, multi-purpose waterproofing membranes, specialized waterproofing tapes, and HVAC duct and pipe wrap. These exterior waterproofing membranes are self-adhering and self-sealing for ease of installation and complete waterproofing protection. MFM products are manufactured in the U.S. and sold through an extensive distributor network around the globe.
