Mechanical & Plumbing

Your Tough Standards,

Made Flexible

Customer success stories in the world of high-performance building drive us.  At REHAU, we manufacture polymer components for mechanical and plumbing systems.  Our goal is to help you build your legacy, because moving energy well with water is a beautiful thing. 

The REHAU Advantage

According to the U.S. Energy Information Administration, residential and commercial buildings account for about 40% of total U.S. energy consumption.  At REHAU, we manufacture polymer products for mechanical and plumbing systems that can play a large part in energy-efficient heating and cooling design and waste-free clean water distribution. We are not a single-use plastic product manufacturer.  We build polymer products that are built for the long-term, which has always been part of our story.
