KRAIBURG TPE, a global TPE manufacturer of a diverse range of thermoplastic elastomer products and custom solutions for a variety of industries, offers the EX and FR2 series of compounds for applications in door and window seals.

Well-sealed doors and windows are important for more than just security. They improve a building's energy efficiency by keeping cool air in and limiting warm air entry during heat waves or draughts in the winter.

If a door or window is properly sealed, it can keep out of a building dust, bugs, noise and unwanted substances, making it a clean, safe and comfortable environment.

KRAIBURG TPE’s EX and FR2 series of compounds are suitable for applications in door and window seals.

For both residential and commercial use, door seals such as weather-stripping seals, door bottom seal brushes, and others are available. However, not all sealing materials are created equal.
