Proglaze® ETA

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.

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 corners are flashed by trimming the silicone extrusion's dart back approximately 1" (2.54cm) to allow for overlapping or proper shingling at the molded corner. Reference the installation instructions for detailed, specific information on creating this transition.

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. For custom color inquiries please contact Tremco's Customer Service in Ashland, Ohio at 1-800-321-6357.

Yes. Please provide shop drawings for the design group's review.

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.

If individual Proglaze ETA components are needed, contact Tremco's Customer Service in Ashland Ohio at 1-800-321-6357 for assistance.

If Proglaze ETA is accidentally torn or cut while being installed or while in service, it can be easily repaired.  The process for repairing the ETA gland is detailed out in our installation instructions.  For additional assistance, contact the Design Engineering Group in Ashland at 800-321-6357.

The metal adaptor allows the Proglaze ETA System 1 or System 2 silicone rubber extrusion to cross over open-ended mullions. This is detailed in our installation instructions. The mechanical fasteners only need to be placed every 12 inches on center. This allows the metal adaptor to span a good distance before it needs to be mechanically supported and should easily span across the open-ended mullion. Many wall systems do apply a metal end cap to allow the caulker to seal the open end of the mullion. By using the metal adaptor, they may not need to apply this end cap.It is up to the wall/window manufacturer, though, to make this decision since they may need to seal their metal for proper water drainage management.

Proglaze ETA System 1 & 2 metal adaptors must not interfere with these supports. It is important that the window and/or wall manufacturer review these conditions with the installer and approve the location of Proglaze ETA and its connection with their window system. To avoid interference with shims and/or anchors, Proglaze ETA System 3 or ribbed silicone sheets may be a better choice.

It is generally the glazing contractor’s responsibility to complete the tie-in and will be part of their bid package. The glazing contractor could always choose to sub this out to another trade.

We occasionally add different sizes and shapes to our standard offering of Proglaze ETA parts.  We currently offer 3”, 4”, 6”, and 8” (76, 102, 152 and 203mm) gland extrusions.

Yes.  These components are referred to as Proglaze ETA Connections.  We have 3D molded corners for inside and outside corners of the wall system in addition to  translucent silicone extrusions in various widths.  These additional components extend the installation capabilities for other complex connections.  Contact Design Engineering in Ashland, Ohio at 800-321-6357 for recommendations as to which materials will best suit the needs of your specific project.

In designing the Proglaze ETA systems, Tremco consulted with a variety of window manufacturers.  Common feedback was a preference for an adaptor length that could be easily handled in the field by a single contractor.  Lengths longer than 60" (1.52m) become cumbersome and may require multiple contractors.  Additionally, 60" (1.52m) lengths are easily packaged and shipped.  Irrespective of length, there is little to no waste of the Proglaze ETA adaptors as ends are easily butted thereby allowing use of shorter pieces that are cut to size in the field.

In most cases, the window system must be installed prior to Proglaze ETA. We have found that many general contractors have adjusted the installation sequence of their wall system to accommodate the use of Proglaze ETA. This will allow the installer to make sure the connection between the window and/or wall system can be made properly, and that our Proglaze ETA system allows them to visually inspect the connection. If the facade is already in place, contact Tremco's Design Engineering Group in Ashland at 800-321-6357 for assistance in determining other available options.
