Thermal > Curtain Wall



Reliance™ is a thermally broken, zone glazed, pressure-equalized curtain wall system offering both captured and structural silicone glazed vertical mullions with multiple system depths and glazing infill options.

Reliance™ Cassette

Reliance™ Cassette Curtain Wall is a 4-sided structurally glazed system that allows the installer to shop glaze the infill onto "cassette frames" using 3M™ VHB™ structural Glazing Tape or Structural Silicone. These pre-glazed frames are then taken to the field and applied to a structural grid of standard Reliance™ or Reliance™-SS curtain wall framing providing a 4-sided structurally glazed appearance with an overall system depth of 6-3/4", 8" or 10-1/2". This system can be used in either new construction or retrofit onto existing Reliance™ or Reliance™-SS installations.


To meet demands for more stringent thermal performance criteria, the Reliance™-HTC curtain wall system was developed by Oldcastle BuildingEnvelope®.


Reliance™-LT is thermally broken utilizing an EPDM push-in thermal isolator. A polyamide pressure plate is available to meet even more stringent thermal performance requirements.


Our Reliance-SS Curtain Wall system is an outside glazed, front set pressure wall curtain wall system that offers screw spline assembly of frames and the ability to shop seal the frame before shipping to the project site.


Energy efficiency has become a critical part of the design process in modern construction. With this in mind, Oldcastle BuildingEnvelope® has developed the Reliance™-TC Thermal Composite Pressure Wall Curtain Wall system.

Reliance™-TC IG

To complement the popular Reliance™ Curtain Wall platform, Oldcastle BuildingEnvelope® has developed a thermal composite inside glazed curtain wall system, Reliance™-TC IG.
