Top Facade Gaskets & Global Standards | BP Materials UK USA

Introduction In the aluminium facade industry, the gasket is the unsung hero. While the aluminium profiles provide the structure and the glass provides the view, the gaskets ensure the system remains airtight, watertight, and energy efficient. Choosing the right material—be it EPDM or Silicone—is vital for meeting modern building codes. Why Material Selection Matters For aluminium systems, gaskets must withstand “thermal bridging” and extreme wind loads.

• EPDM Gaskets: Known for their durability and “mechanical” engagement into aluminium raceways. They are the workhorse of the industry, offering excellent resistance to weather and aging.
• Silicone Gaskets: When projects demand high-temperature resistance or specific colours to match the facade, silicone is the premium choice. It is also the preferred material for setting blocks to prevent direct glass-to-metal contact.

Navigating Global Standards When specifying gaskets for international projects, compliance is non-negotiable. Look for materials that meet:

1. ASTM C864: For dense elastomeric seals.
2. DIN 7863: The German standard for glazing and panel gaskets, often used as a benchmark in Europe and the Middle East.
3. BS 4255: The UK standard for weather exclusion gaskets.

BP Materials UK: Innovation in Extrusion As a leader in performance materials, Berzelius Performance Materials UK offers advanced Co-Extrusion Profiles. By combining different hardnesses of silicone or EPDM in a single profile, we help fabricators reduce installation time while improving the compression seal. Our gaskets are designed to be compatible with all major aluminium systems, ensuring weathertight joints in windows, doors, and skylights. Conclusion The future of sustainable architecture depends on the “tightness” of the building envelope. By using high-grade gaskets from BP Materials, you ensure your aluminium facade system performs at its peak for decades.
