Weather-Resistant Exterior Expansion Joint System with Integrated Moisture Barrier

Product Description

The Aluma-Flex Exterior Expansion Joint System is a multi-component architectural joint assembly designed for vertical and horizontal exterior applications. It features a robust aluminum frame paired with a high-movement Santoprene or EPDM seal, specifically engineered to maintain structural integrity and aesthetic continuity while allowing for significant thermal expansion and seismic movement.

Key Features

• Total Weather Seal — Provides a 100% watertight barrier against rain, wind, and debris.
• Multi-Directional Movement — Accommodates expansion, contraction, and lateral shear forces.
• UV & Ozone Resistant — Durable elastomeric seal designed to withstand prolonged sun exposure without cracking.
• Flush Finish Design — Minimizes visual impact on the building façade while remaining maintenance-free.
• Integrated Vapor Barrier — Includes a secondary moisture membrane to prevent internal wall condensation.
