Proglaze ETA Connections

Proglaze® ETA Connections are pre-engineered silicone materials used as a transition assembly between the window or wall system and adjacent air and vapor barrier materials. The assembly is comprised of a flat single or double ribbed silicone extrusion of varying widths, which are adhered to the building facade with Spectrem® 1 Silicone Sealant to ensure a durable connection and positive seal. The opposite end of the ribbed silicone extrusion will span unsupported onto the wall and/ or window system, which is adhered with Spectrem 1 Silicone Sealant. This connection will provide a long-term durable flexible connection between the two components.


  • Bridge continuously between the window and/or curtain wall and the adjacent air and vapor barrier materials
  • Absorb thermal movement and wind-loading stresses
  • Allow the material to span and seal across irregular window geometries
  • Allows the installer and/or inspector to see through the gasket to verify the recommended amount of sealant is properly applied to ensure an effective seal is achieved, while the ribs of the gasket’s design ensures a minimum sealant thickness
