Two Layers of Protection, One Reliable Seal: Double-Layer Door Sealing Materials

The Double-Layer Door Sealing Material is the premium sealing solution for airtight cleanroom doors, medical ward doors, and observation windows — a dual-layer compression gasket that provides redundant sealing for enhanced airtightness and pressure integrity. Manufactured from high-resilience silicone or EPDM, the double-layer design ensures that even if one layer is compromised, the second continues to seal — delivering dependable containment of drafts, dust, and airborne particles. Chemical-resistant and easy to install, it is the trusted sealing material for GMP cleanrooms and medical facilities.

Dual-Layer Redundant Sealing
The double-layer design provides redundant sealing — even if one layer is compromised, the second layer maintains the airtight barrier — enhancing reliability.
Enhanced Airtight Performance
The two sealing layers work together to achieve enhanced airtightness — maintaining pressure differentials and preventing drafts, dust, and particle ingress.
High-Resilience Material
Manufactured from high-resilience silicone or EPDM — excellent compression recovery that maintains effective sealing over years of door operation.
Chemical & Disinfectant Resistant
Silicone and EPDM withstand common cleanroom and hospital disinfectants — VHP, alcohol, quaternary ammonium, and chlorine-based agents — without degradation.
Excellent Temperature Resistance
The sealing material performs reliably across a wide temperature range — suitable for cold storage, cleanrooms, and heated production areas.
Easy Installation & Replacement
Available as adhesive-backed or profile-mounted strips — simple installation and easy replacement for maintenance.
Wide Application
Suited to airtight cleanroom doors, medical ward doors, observation windows, pass boxes, and equipment access doors.
