This flexible rubber door and window sealing strip is specifically engineered for aluminum extrusion profiles. Its elastic structure conforms to compatible frame surfaces while maintaining a flexible sealing interface that adapts to movement and environmental conditions.

When properly installed, the strip effectively closes gaps between aluminum profiles and adjacent components, reducing air movement, dust penetration, and drafts while providing essential cushioning between surfaces. The flexible profile is ideal for systems where doors or windows experience repeated movement and operation.

Our product range includes multiple cross-sectional designs, allowing selection of different profiles for various aluminum extrusion grooves. Hollow structures provide additional flexibility, while other profiles are optimized for edge sealing or surface-mounted applications.
