Tremco Proglaze® ETA – Engineered Transition Assembly
Proglaze ETA reference chart
TDS
Proglaze ETA is a pre-engineered silicone rubber extrusion that seals the transition between window or curtain wall systems and the adjacent air/vapor barrier. It creates a continuous, flexible air- and watertight connection at the spots where leaks most often start, including joints affected by construction tolerances, movement and irregular geometry.
Features
- Bridges wide and irregular gaps that a sealant bead can’t
- Absorbs thermal movement and wind-load stresses
- Integral dart makes installation easier
- Translucent silicone lets you visually confirm proper sealant wet-out
- Available in a range of widths, profiles and molded corners
- Ozone resistant (ASTM D1149)
Best For
- Window-to-air barrier connections
