Structural Design
Description
The AlumaSeal L-Series is a high-performance, L-shaped expansion joint system designed specifically for perimeter conditions where a horizontal floor slab terminates at a vertical wall or column. Utilizing robust extruded aluminum side profiles and a high-quality EPDM elastomeric insert, this system provides a secure, flexible bridge that accommodates significant structural movement.
The "L" configuration allows for one-sided anchoring, making it ideal for joints that require a clean, flush finish against vertical surfaces. The multi-ribbed EPDM insert is engineered to absorb thermal expansion and seismic shifts while preventing the accumulation of dirt and moisture within the structural gap.
Performance Core
Key Features
- Asymmetrical "L" Profile — specifically engineered for perimeter joints at wall-to-floor junctions.
- High-Strength Aluminum Frames — extruded alloy side members provide excellent edge protection for concrete slabs.
- Replaceable EPDM Insert — multi-ribbed rubber seal offers high flexibility and is easily maintained or replaced if damaged.
- Seamless Integration — low-profile design allows for a flush transition with various floor finishes like tile, epoxy, or stone.
- Seismic & Thermal Movement — handles multi-directional displacement caused by structural settling and temperature changes.
- Durability & Resistance — EPDM component is highly resistant to UV, ozone, and common cleaning chemicals.
