In many cavity wall-to-window and air barrier-to-window applications, window framing design and wall construction present many challenges associated with effective connection of these systems with a conventional sealant bead.  Bond line surface areas, incompatibility of components, adhesion between products and ultimate movement capability are all concerns.  Proglaze ETA addresses all of these concerns thereby minimizing long-term risk and ensuring designed performance requirements.  Contact your local Tremco Sales Representative for your job-specific requirements.

Proglaze ETA was not designed for these types of windows.  Tremco would be happy to review your specific project requirements and assist in developing a solution to address this connectivity for your application.  Contact the Design Engineering Group in Ashland, Ohio at 800-321-6357 for assistance.

Non-standard corners may be designed but will have longer lead times and minimum production quantities.  The cost for tooling can be over $10,000, so custom designs will be addressed as needed. In designing the standard systems, Tremco has tried to anticipate several common job issues that can be addressed through slight modification or adaptation of standard parts.  Contact the Design Engineering Group in Ashland, Ohio at 800-321-6357 for job-specific requirements and recommendations.

Yes. Given the many possible variables associated with selection and use of Proglaze ETA, the Design Engineering Group in Ashland, Ohio (800-321-6357) should be contacted for assistance.  Please provide shop drawings and the design group will work with you to develop an appropriate Proglaze ETA solution for your specific project.

Tremco offers a variety of ETA systems to address variations in window design and placement on the building facade. There are three standard Proglaze ETA systems. These can be viewed through website links for application details. The standard Proglaze ETA systems are as follows: System 1 – 6” wide extrusion (requires Extruded Aluminum Adaptor) System 2 – 6” wide extrusion with off-set dart (requires Extruded Aluminum Adaptor) System 3 – 8” wide extrusion developed for Pressure Bar Systems (does not require Extruded Aluminum Adaptor)

Weeps need to be kept open to prevent accumulation of water in the system.  The original Proglaze ETA System 1 is applied at what some would call the wet-line. This is where the primary seal connects the window and/or wall frame to the façade covered with the air barrier product. Proglaze ETA System 2, with off-set dart design, has the ability to seal the outer surface of the window and/or wall system from the cavity. This would then prevent any water from penetrating any metal-to-metal joinery not properly sealed. It would also prevent water from entering the glazing pocket and penetrating around improperly sealed metal-to-metal joinery.

Proglaze ETA has been installed successfully with other air barrier manufacturers' products.  Tremco will not be able to offer the 5-year air-and-moisture connection performance warranty in this case, however, as it is only available when Proglaze ETA is used in conjunction with Tremco's ExoAir Air Barrier Systems.  The 5-year connection warrants that air or water shall not pass through the Proglaze ETA system as long as the system has been installed consistent with Tremco's installation instructions.

Yes, Tremco Proglaze ETA can be extruded in colors other than the standard transluscent sheet.  ETA is extruded from transluscent silicone in order to provide on-site quality control measures as effective and continuous wet out of the sheet onto the perimeter substrate using Tremco Spectrem 1 silicone sealant can be monitored.  Use of a pigmented silicone would negate this QC opportunity.

Yes.  Proglaze ETA has passed industry-standard air and water performance testing when installed under a stucco façade.  Additionally, the Proglaze ETA system was specified and installed during the refurbishment of our corporate headquarters building in Beachwood, Ohio in conjunction with an EIFS system.
