Hybrid Mullion Seal Design: Sponge + Solid EPDM
In door and window systems, mullion seals are key to airtightness, acoustic control, and thermal efficiency. This profile combines a closed-cell EPDM sponge core with solid EPDM edges, delivering both flexibility and dimensional stability. Key Engineering Advantages:• Lower closing force with high elastic recovery thanks to the sponge core.• Secure fit & stability from solid …
