XHM205F

The XHM205F is engineered for high-precision architectural environments where traditional, bulky seals would interfere with the tight tolerances of premium door sets. This 11 mm wide profile is the invisible guardian of your doorway, providing a minimalist aesthetic without sacrificing industrial-strength fire protection.

Precision Gap Management: Designed specifically for the most demanding tolerances, the XHM205F addresses the “micro-gaps” (1.2 mm to 1.8 mm) found in high-end swinging and sliding doors. In standard operation, the coated polyurethane foam acts as a high-performance weather strip, blocking drafts and dust while providing a luxury cushioned closure. This helps preserve the door’s finish by preventing the harsh metal-on-wood or metal-on-metal contact common in commercial settings.

Active Life-Safety Shielding: When disaster strikes, the XHM205F transforms. Upon reaching critical temperatures, the hidden intumescent core triggers a powerful expansion phase. It swells to three times its thickness, effectively turning the tiny door clearance into a solid, fire-resistant wall of carbonaceous char. This physical barrier is crucial for compartmentalization, ensuring that a fire localized in one room cannot “inhale” oxygen from the rest of the building or “exhale” dangerous flames through the door perimeter.

Uncompromising Barrier Integrity: Smoke is a silent killer, and the XHM205F is built to stop it. Rigorous 90-minute testing proves that this seal maintains a vacuum-like integrity against smoke migration, even when the surrounding frame is under intense thermal stress. Its ability to withstand temperatures up to 980°C without turning to ash means the seal remains active and functional long after standard gaskets would have failed, providing safe passage for occupants and protection for property.
