Weatherstripping is the process of sealing openings such as doors, windows, and trunks from the elements. The term can also refer to the materials used to carry out such sealing processes.

The goal of weatherstripping is to prevent rain and water from entering entirely or partially and accomplishes this by either returning or rerouting water. A secondary goal of weatherstripping is to keep interior air in, thus saving energy on heating and air conditioning.

SRP can custom fabricate weatherstripping by combining a substrate such as rubber, foam, and sponge to the right adhesive to guarantee the perfect seal every time. Depending on the application there are a variety of materials used for weatherstripping applications.

Common weatherstripping materials:
  • PORON Urethane Foam
  • Silicone Sponge
  • PVC Foam
  • Closed Cell Sponge
  • Open Cell Sponge
  • Polyurethane Foam
  • Cellular Urethane
  • EVA
Common weatherstripping applications:
  • Doors + windows
  • Automotive components
  • Building + Construction
  • Home improvement
  • Outdoor appliances
  • HVAC equipment

Using a material such as PORON® Urethane, you are not only able to provide a tight seal from indoor and outdoor elements, but since the material inherently does not take a compression set, it is perfect for applications such as HVAC entryways that need to be removed for servicing. The gasket will stay in tact to be reused again and again.

By employing specialized equipment and providing full-service solutions—from design assistance and prototyping, to acquiring and working with cutting-edge, preferred materials—SRP stands out as a leader in custom gasket fabrication and die and die-less cutting services. Specifically for weatherstripping we utilize a combination of our advanced laminating and slitting technologies to provide high quality products at cost-competitive prices.

SRP’s dedicated engineers are available to provide their expertise to assist you with your next project and help you obtain top-quality materials for parts and components that meet your exact specifications.
