Door & Window Profiles
High-performance architectural and automotive door and window rubber profiles engineered to block drafts, driving rain, acoustic noise, and extreme thermal transfer. Extruded with precision retaining feet that snap-lock securely into aluminum, PVC, and steel mullion channels.
Types & Configurations of Door & Window Profiles
Acoustic Perimeter Door Seals
Tear-resistant hollow bulb seals providing soft closure feel and high acoustic STC rating.
Glazing Wedge Gaskets
Tapered push-fit EPDM wedge gaskets securing double-glazed insulated glass units.
Sliding Door Brush-Backing Profiles
Extruded elastomer base channel designed to retain polypropylene brush filaments.
Curtain Wall Structural Profiles
Heavy-duty weather barrier gaskets accommodating structural wind load deflection.
Automotive Door Primary & Secondary Seals
Co-extruded sponge bulb with solid base and internal metal clip retention.
Key Industrial Applications
