FlexClad-400™ is the flexible, weatherproof, economical, and easy-to-install protective solution for pipe and duct applications.

To protect your costly investment of your piping or ductwork system , and significantly extend its service life, specify FlexClad-400 sealing system from MFM Building Products. Why?

FlexClad-400 is a patented, water and weather-resistant, pre-fabricated, self-adhering, sheet-type protective membrane. The top surface is UV-resistant embossed aluminum that reflects heat and can aid in reducing energy costs.

It is bonded to extremely tough, high-density polyethylene reinforcement material that is backed by a layer of aggressive, rubberized asphalt.

Available in four colors: aluminum, white, gray and tan. Self-sealing around punctures, pins, screws, flanges and banding, FlexClad-400 resists water leaks and vapor transmission, reflects sunlight to reduce interior temperature, and preserves the efficiency and integrity of thermal insulation.

And because it provides superior protection for most pipe or duct systems, plenums and storage tanks, it saves time, material, labor, and future utility costs.
