Proglaze® ETA 3-D Molded Corner Connections are engineered from 40 Durometer Dense Translucent Silicone used for making connections to our ExoAir® Air Barrier Membrane systems with Spectrem® 1 Silicone Sealant. The 3-D molded corners have been designed in such a way so that they may be used to overlap one another or used in conjunction with other Proglaze ETA components to accommodate complex transitions.
