Top Load Seals | Plastic Extrusion Profiles

Top load vinyl seals provide sealing and insulation along the tops of glass windows and doors. Although they are easy to install, these door and window seals may not be the right choice for some environments. For example, in schools, daycares, and residential settings, children may pluck these extrusions loose, which can result in premature seal failure.

Top Load Seal Materials

Most top load door seals and top load window seals are made from 70-durometer EPDM or Santoprene. Flexible polyvinyl chloride (PVC) is not a good choice because of the size and thickness of these extrusions. Door seals and window seals are exposed to sunlight, and PVC is subject to compression set under these conditions. When a gasket over-compresses, leaking can occur.

EPDM Top Load Seals

EPDM is a good choice for these rubber glazing seals. A synthetic elastomer, EDPM provides excellent resistance to wind and water. It also resists exposure to ozone, sunlight, and severe weather conditions, including a range of warm weather and cold weather temperatures.

Santoprene Top Load Seals

Santoprene is a thermoplastic vulcanizate (TPV) and thermoplastic elastomers (TPE) that combines the processing properties of thermoplastics with the performance characteristics of vulcanized rubber. This TPV has elastomeric properties that are similar to EPDM but is longer-lasting. Santoprene costs more but is a good choice for applications for applications where doors and windows need to last for decades.
