Design Engineering, Inc. (DEI) has been a trusted brand in heat control products since 1995. They specialize in providing exceptional quality products primarily sold through the performance distribution system.

But what sets DEI apart is their ability to work with customers to solve their heat and sound control problems. With a dedicated in-house design team, DEI collaborates with customers to define their specific needs and design tailored solutions using the correct materials. They can quickly create prototypes for inspection and evaluation purposes.

Once the design is approved, production begins based on the customer's requirements. Over the years, DEI has developed custom solutions for various industries including aviation, powersports, racing, marine, and even locomotive. They have also undertaken build to spec contract work for commercial, industrial, and military-related businesses.

DEI was founded by industry veteran Dale Markley in Cleveland, Ohio. Under Dale's vision, the company expanded and relocated to a larger complex in 2004. Today, with Dale's son David leading the company, DEI continues to develop and improve products, ensuring they remain industry leaders.

At DEI, the customer is at the forefront of every decision they make. They strive to bring innovative, quality products that exceed expectations. In the rare event of an error, DEI is committed to making it right immediately, because without their customers, they are nothing
